Hi there,
I just installed ActivePerl (ActiveState Software ActivePerl 5.20.2001) but it doesn't seem to communicate with my R Studio program since I get this message everytime I try to run the command "library(gdata)" after I have installed the gdata package. Do you know what I am doing wrong?
Thanks a lot!!
Here's what R Studio says:
"> install.packages('gdata')

... I am sorry for the last bit that is in Danish, but I hope it still makes sense.
Best regards
