Release 3.1.0 - 2020-09-12

Major change:

  • Removed gdata from imports by bringing into the package the functions nobs and reorder.factor.
    • Removed the gdata package from “imports” since it is currently broken and is scheduled to archive in 2020-09-25 (leading to gplots to be archived as well, unless this is resolved). By removing this connection, gplots will be able to remain safely on CRAN. In prectice, I’ve moved reorder.factor and nobs into this package, as well as removed the use of ‘nobs’ from some examples.
    • Added the reorder.factor and nobs function (from gdata)

Release 3.0.4 - 2020-07-05

Bug Fixes:

  • Fix “no visible global function definition for ‘%||%’”: The package imports .memberDend and .midDend from stats in an unsafe way (i.e. using :::). I’ve moved to manually copy-pasting the functions into the package in order to keep it a bit safer. It has the downside of not using whartever improvements/bugfixes are intrudced to these functions moving forward. But for the time being, it’s a reasonable solution.

Release 3.0.3 - 2020-02-26


  • Tal Galili took over to make sure the package stays on CRAN.
  • Moved to knitr

Release 3.0.1 - 2016-03-30

Bug Fixes:

  • An error in plotLowess() prevented it from finding objects in the caller’s environment.

  • The manual page for heatmap.2() stated the incorrect type for the ‘layout’ element of the return list. It is a named list, not a named numeric vector.

Release 3.0.0 - 2016-03-28

New Features:

  • venn():
    • now support matrices of indicator values. Previously indicator values were only supported when supplied as a dataframe.
    • The ‘intersections’ attribute returned from venn() has been improved so that goups are labeled using set names instead of indicators, and are ordered from simplest to most complex set intersection.
  • New angleAxis() function to create axis labels with rotated text.

  • heatmap.2():
    • heatmap.2() can now be used to plot subsets of a previous heatmap.
    • Decrease the granularity of the carpet in heatmap.2()’s color key to avoid visual artifacts.
    • Returned object now includes ‘layout’ element that contains layout information. (Patch provided by Jenny Drnevich.)
  • lowess():
    • New function plotLowess() to display a scatter plot with a superimposed lowess curve.
    • The lowess() functions now returns a list object of class ‘lowess’
    • A new lowess method for plot() method for ‘lowess’ objects that generates a scatterplot of the raw data with a lowess curve superimposed.

Bug Fixes:

  • Defunct message for boxplot.n() was recommending the wrong function.

  • heatmap.2():
    • Remove debugging print() statement.
    • Now properly sets ‘srtCol’ default if missing and ‘colCol’ is specified.
    • Corrected a bug causing “Error in : figure margins too large” to occur when ‘key=FALSE’. (Reported and patch provided by Sveinung Gundersen.)
    • Corrected a bug causing an error when “Rowv=FALSE” or “Colv=FALSE”.
    • Corrected message when “Rowv=FALSE” or “Colv=FALSE” and the the “dendrogram” argument requested the corresponding dendrogram.
  • venn():
    • Fix warning message that was missing spaces between words.

Other Changes:

  • The smartlegend(), plot.lm2(), and boxplot.n() functions are now defunct. Please use grephics::legend(), lmplot2() or boxplot2() respectively.

Release 2.17.0 - 2015-05-01

New Features:

  • heatmap.2() has two new arguments, ‘colRow’ and ‘colCol’ to control the color of row and column text labels. See the man page for examples.

  • heatmap.2() has been modified to make it easier to extract and plot subclusters from a large heatmap. Simply pass the dendrogram of the subcluster together with the full data matrix and, optionally, the breaks of the full heatmap in order to obtain the same color scaling. (Suggestion and patch contributed by Ilia Kats.)

  • venn() now returns a list of the members of each set intersection in the attribute ‘intersections’. This can be disabled using the argument ‘intersection=FALSE’ (Patch by Steffen Möller.)

Bug Fixes:

  • In heatmap.2(), the color key now properly handles color breaks that are not equally spaced. (Issue reported by Tim Richter-Heitmann.)

  • In heatmap.2(), row/column traces in could be plotted on the wrong row/column.

  • plotCI() now properly respects the ‘type=’ argument. (Bug report and correction by Wiktor Żelazny.)

  • Remove stray browser() call from overplot()

  • In the balloonplot() examples, explicitly specify the ‘neworder’ argument to gplots:::reorder.factor to prevent errors.

Other Changes:

  • smartlegend() is now deprecated because the relative positioning feature (‘top’, ‘right’) has been added to graphics::legend(). Calling smartlegend() will generate a warning.

  • boxplot.n() and plot.lm2() are defunct have been removed. Use of these functions will now generate an error.

  • Update out-of-date URLs in man pages.

Release 2.16.0 - 2015-01-02

New Features:

  • plotmeans() has a new argument, ‘text.n.label’ which specifies the text used for labeling the number of elements in a group.

Bug Fixes:

  • plotmeans() now respects (optional) graphical arguments captured in ‘…’ when drawing the x axis.

Release 2.15.0 - 2014-12-01

New features:

  • Convert bandplot() to S3-method dispatch and add method for class formula, so that ‘bandplot( y ~ x, data=dataframe )’ now works as expected.

Other changes:

  • heatmap.2() now uses a local non-byte-compiled copy of plot.dengrogram, because the byte-compiled stats:::plot.dendrogram uses a recursive algorithm that generates a ‘node stack overflow’ error for deeply nested dendrograms and the node stack size cannot be changed at execution time. Instead, tne local non-byte-compiled gplots:::plot.dendrogram will trigger a recursion limit for such dengrograms. heatmap.2() will detect this error and recommend that the user increase the recursion limit (via, e.g. ‘options(“expressions”=20000)’ ) and rerun.

Release 2.14.2 - 2014-09-17

Bug Fixes:

  • heatmap.2() was not respecting key.title=NA when“none”.

  • Correct the man page for heatmap.2 to state that the default color for ‘notecol’ is cyan.

  • In heatmap.2(), modify default arguments to ‘symbreaks’ and ‘symkey’ to make the logic more evident by replacing min(…) with any(…). (The previous code executed properly, but relied on implicit coercion of logicals to numeric, obscuring the intent.)

  • Calling heatmap.2 with deeply nested dendrograms could trigger a ‘node stack overflow’ error. Now, this situation is deteceted, and a message is generated indicating how to increase the relevant recursion limit via options(“expressions”=…).

Release 2.14.1 - 2014-06-30

Bug Fixes:

  • Correct heatmap.2() bug in Colv dendrogram object dimension checking introduced in 2.14.0. (Reported by Yong Fuga Li.)

Release 2.14.0 - 2014-06-18

Bug Fixes:

  • heatmap.2(): Fix typo in heatmap.2() that caused an error when ‘Rowv=FALSE’. (Reported by Yuanhua Liu.)


  • heatmap.2(): Add new ‘reorderfun’ argument to allow the user to specify an alternative function to reorder rows/columns based on row/column dendrogram. (Suggested by Yuanhua Liu.)

  • heatmap.2(): Center margin labels.

  • heatmap.2(): Check size of user-provided Rowv and Colv dendrogram objects to ensure they match the dimensions of the data.

  • Add references to man page for hist2d() and ci2d() to the new r2d2 package which implements an improved algorithm for 2-dimensional emprical confidence regions.

Release 2.13.0 - 2014-04-04

Bug Fixes:

  • heatmap.2 was not properly handling row trace reference line (‘hline’). Patch submitted by Ilia Kats.


  • In heatmap.2, when the row or column trace is enabled, show the corresponding reference line in the color key.

  • In heatmap.2, a new ‘extrafun’ argument is provided that allows the user to specify a function to be called before the function returns. This allows the user to add additional plots to the page.

Release 2.12.1 - 2013-10-14

API Changes:

  • boxplot.n() has been renamed to boxplot2() to avoid potential S3 method calling issues.

  • plot.lm2() has been rename to lmplot2() to avoid potential S3 method calling issues.


  • Add heatmap.2() parameters to control row and column label rotation (‘srtRow’, ‘srtCol’), justification (‘adjRow’, ‘adjCol’), and space from plot edge (‘offsetRow’, ‘offsetCol’).

Bug Fixes:

  • Fix error in in venn() when all groups contained the same number of TRUE cases.

  • Correct error in overplot() when that occured when a group-category contained no finite values.

Other Changes:

  • Changes to overplot() to avoid warnings from upcoming enhancements to R CMD check.

  • Move several packages from Depends to Imports or Suggests.

  • Packages caTools and KernSmooth now have namespaces, so import needed functions in NAMESPACE.

  • Mark one example in manual page for ci2d ‘dontrun’ to avoid timing warning in R CMD check.

Release 2.11.3 - 2013-06-27


  • Modify sinkplot() to use a local environment rather than the global environment, to conform to CRAN policies.

Bug Fixes:

  • Fixed typo/spelling error in plotmeans() man page.

Release 2.11.2 - 2013-03-24


  • Add ci.width argument to barplot2() to allow varying the length of the ‘t’ at the end of confidence interval bars.

Bug Fixes:

  • Fix error in heatmap.2 when colsep argument had length 1.


  • Update manual page for lowess.default() to match changed argument list for lowess() in R 3.0.0

Release 2.11.1 - 2012-12-14

Bug Fixes:

  • Replace corrupted BalloonPlot.pdf in inst/doc.

Release 2.11.0 - 2012-06-08

New Features:

  • Objects returned by hist2d() have been changed: 1) $x and $y now contain the n midpoints of the bins in each direction 2) $x.breaks, $y.breaks now contain the n+1 limits of the bins in each direction.

  • Add lwd argument to plotmeans().

Bug Fixes:

  • Correct error in handling binning in hist2d(): (N+1)x(N+1) bins were being created instead of NxN bins, and the highest row/column in each direction was being omitted from the results and plot.

  • Changes to fix R CMD check warnings

Release 2.10.1 - 2011-09-02

New features:

  • Make results of hist2d() and ci2d() into objects, and add print() methods to display them.

Release 2.10.0 - 2011-08-26

New Features:

  • New ci2d() function to create 2-dimensional empirical confidence intervals utilizing KernSmooth:bkde2D and gplots::hist2d(). See ?ci2d for details.

  • Add ‘alpha’ argument to rich.colors() to control transparency.


  • Accellerate hist2d by replacing for() loop with tapply(), and allow user to specify summary function applied (per suggestion by Peter Hagedorn).

Bug Fixes:

  • Correct error in heatmap.2() that arises when data includes NA values (identified by Melissa Key).

Release 2.8.0 - 2010-06-10


  • venn() now returns an object of class venn() and a plot method for this class is provided.

  • Manual page for venn has been improved, based on contributions by Steffen Moeller

Release 2.7.5 - ??


  • Performance of ‘hist2d’ improved thanks to a suggestion from Joerg van den Hoff.

Release 2.7.4 - 2009-11-12

Release 2.7.2 - 2009-05-08

Bug Fixes:

  • Correct bug reported by Ken Lo: cox2hex() had blue and green components swapped.

Release 2.7.1 - 2009-05-08

New Features:

  • Enhancements to heatmap.2()

    • New arguments ‘lmat’, ‘lhei’, and ‘lwid’ that allow controlling component plot layout. Users can now resize and rearrange plot components.

    • heatmap.2() will now compute color breakpoints that are symmetric about 0 when the new ‘symbreak’ parameter is TRUE. This parameter, as well as the symkey parameter now default to TRUE whenever negative values of x are present, and to FALSE othewise.

    • the heatmap.2() return value now includes additional useful information, including: call, rowMeans, rowSDs, colMeans, colSDs, carpet (reordered and scaled ‘x’ values), rowDendrogram, colDendrogram, breaks, col, vline, hline, and colorTable. Of these, the most useful are breaks, col, and colorTable. The latter is a three-column data frame providing the lower and upper bound and color for each bin.

    See the manual page for complete details and examples.

  • New function venn(), contributed by Steffen Moeller (Thanks Steffen!) to generate Venn diagrams for up to 5 sets. See ?venn for details.

  • Performance of bandplot() has been dramatically improved, in part by using runsd() and runmean() from the caTools package. As a consequence, gplots now depends on the caTools package.

  • Improved performance of gplots::plot.lm for large lm objects by using the new bandplot() and by using fitted() instead of predict() to obtain y-hat.

  • Add ‘scale.range’ argument to balloonplot(), option to scale balloons so [min,max]->[0,1] (‘relative’) or [0,max] -> [0,1] (‘absolute’).

Bug Fixes:

  • balloonplot() now properly handles dimension labels provided by ‘xlab’ and ‘ylab’

  • plotCI now properly handles ‘NULL’ and ‘NA’ values for ui, li, uiw, and liw.

  • Corrections of minor typos in man pages
