Dear all, I have a question that is probably pretty stupid, so apologies in advance...
I do a simple > mydata.tab <- by(my.data.frame, my.data.frame$category, colMeans) ...works fine, but I need to output the results to some "flat" file (kind of table) to work with it in Excel etc. So I am doing now > capture.output(data.frame(unlist(mydata.tab)), file="mydata.txt") ...and process the result in Excel. Do you know a more pretty way to do this task? Perhaps something other than 'by()' to make a table of colMeans? Many thanks!
