Hi all,

I惴 trying to "recuperate" old files I wrotte and I惴 trying to execute on R
version 2.13.0 (2011-04-13), the thing is I execute my old file and nothing
happens...I suposse I need to install some library but there no appears no
message, no text telling "required grafics library" or something like that.
How can I see wich libraries need to execute a file?

Many thanks in advance﹛﹛

Do you recommend to work with the last avaliable CRAN R version?
