Here's a reproducible bug in barplot in 1.9.0 (based on an email I got this morning from Richard Rowe): x <- table(rep(1:5,1:5)) barplot(x) The problem is that table() produces a one dimensional array, and barplot() doesn't handle those properly now. The offending line is this one: $ cvs diff -r 1.3 barplot.R [junk deleted] 43c43 < width <- rep(width, length.out = NR * NC) --- > width <- rep(width, length.out = NR) In the example above, x gets turned into a matrix with NR=1 row and NC=5 columns so only one bar width gets set.
