R-help,
I have a list of several data frames.
I want to compute the "rowSums" of the columns of these data frames but first one.
... "but first data.frame" or "but first column"?
"but first data.frame": lapply(my.list[-1], rowSums)
"but first column": lapply(my.list, function(x) rowSums(x[,-1]))
Uwe Ligges
Something like this
lapply(my.list,rowSums)
Thank you
