click_rotate(
  x,
  plot = TRUE,
  plot_after = plot,
  horiz = FALSE,
  continue = FALSE,
  ...

Examples

# create the dend:
dend <- USArrests %>%
  dist() %>%
  hclust("ave") %>%
  as.dendrogram() %>%
  color_labels()
if (FALSE) {
# play with the rotation once
dend <- click_rotate(dend)
dend <- click_rotate(dend, horiz = TRUE)
# keep playing with the rotation:
while (TRUE) dend <- click_rotate(dend)
# the same as
dend <- click_rotate(dend, continue = TRUE)
}
