Dear list,

I have a list of data.frames (generated by "by"), that I want to "stack" into a single data.frame.

I can do this by cbind, but only by subsetting the list explicitly like this:

cbind(l[[1]],l[[2]],l[[3]],l[[4]])

I find this ugly and not very general.

I tried
cbind(l)
cbind(l[[1:4]])
but they do not give the right result.

Please help!

Best regards
Thomas
