I'm tryin to make a contingency table on R using the Melanoma data set from MASS package using Rcmdr.

local({
    .Table <- xtabs(~sex+status+ulcer, data=Melanoma)
     cat("\nFrequency table:\n")
     print(.Table)
})

Every time i try to make a contingency table (also with other data sets) R tells me that the "numb" agument is invalid and it doesn't have a predefined value.

Works okay in R (after `library(MASS)`) - so seems a Rcmdr issue. – user20650 Oct 28 '17 at 18:51
It also works fine for me. – nghauran Oct 28 '17 at 19:22
should I update rcmdr? – Giuseppe Minardi Oct 28 '17 at 20:34
@GiuseppeMinardi ; possibly. I just installed Rcmdr v2.4.1, using R3.4.2. When I started Rcmdr from the terminal, your code ran without error. – user20650 Oct 28 '17 at 22:36
I uploaded all the packages and it doesn't work – Giuseppe Minardi Oct 29 '17 at 09:23
I mean i have R 3.4.2 and Rcmdr v2.4.1 and it still gives me an error – Giuseppe Minardi Oct 29 '17 at 09:26
I can't reproduce, but maybe someone else can. Can you add the results of `sessionInfo()` to your question please, and mention your workflow - using rstudio, conda etc – user20650 Oct 29 '17 at 11:20
