list of frames without first element
From: Luis Rideau Cruz
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.
Something like this
lapply(my.list,rowSums)
You're almost there: lapply(my.list, function(x) rowSums(x[-1])) Andy
