How can I rbind a list of data frames using only specific columns? Something like do.call(rbind, data) works fine, but I dont't know how to exclude a vector of specific columns. Dropping unnecessary columns afterwards seems is ok, but maybe there is a cleaner way to do this?

1Do you want to `merge` or `rbind`? You need to get your definitions straight. – David Arenburg Feb 03 '16 at 12:35

Edit original post. I want to use `rbind`. – Matthias Preu Feb 03 '16 at 13:24

I can simply use subset (thanks to @Jaap):
do.call(rbind, lapply(data, subset, select=c("use_this", "and_this")))
