‘hist()’ for ‘"Date"’ or ‘"POSIXt"’ objects would sometimes give misleading labels on the breaks, as they were set to the day before the start of the period being displayed. The display format has been changed, and the shift of the start day has been made conditional on ‘right = TRUE’ (the default). (PR#16679)
The ‘as.hclust’ method for ‘"dendrogram"’s failed often when there ties in the heights.
