Dear R users,

How can I do this in R?
Hi catalin,
If I understand your question, which I think is:
I want to extract columns from different data frames with differing
numbers of rows and store them in a single object.
The answer is probably to use a list:
datalist<-list()
datalist[[1]]<-dataframe1[,"variable1"]
datalist[[2]]<-dataframe2[,"variable3"]
...
where each element of "datalist" may have different numbers of values.
Jim
