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.
