Thank, Judit -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Thomas Adams Sent: Monday, December 12, 2011 3:22 PM To: Bert Gunter Cc: r-help@r-project.org Subject: Re: [R] Boxplot of multiple vectors with different lengths Bert, I may be mistaken, but I thought Ryan wrote "write code that automatically *imports data* from different files (with different lengths-just one variable)", so, I was referring to doing something with the data before it gets into R. I understand that one should not need to write out data and then re-read it in some way. As I said, those more experienced with R will probably offer better ideas.
