Full_Name: Leo van Romunde Version: 2, 1, 0 OS: Win XP prof. sp1 Submission from: (NULL) (81.58.34.90) When we type the following R gives an error:
a = c(1, 2) b = c(1, 2) boxplot (a ~ b)
Error in list(a, b) : invalid 'envir' argument When we do exactly the same on another machine (Win2000) it works correctly. Any suggestions?
You probably have overwritten boxplot() or something with your own object. This works fine for me in 2.1.0 (but you should upgrade to 2.1.1 for other bug fixes). Duncan Murdoch
