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.
