Thank you for your earlier help, I have a couple of related questions. With the lapply function, is it still possible to assign column names to each column of every data frame, again I have tried and it doesn't seem to like it..
and is it also possible to assign names to each data frame when I do lapply rather than each one being a subset of a larger frame (I don't seem to be able to attach these as individual objects).
