[R] append data

[ben@zoo.ufl.edu]

rbind(as.matrix(rawlist),matrix(0,ncol=3,nrow=4))

 will do it, although depending on what you're doing next you may want to
turn the result back into a dataframe after attaching the zeros.

  I can't quite figure out the logic that says why

rbind(rawlist,matrix(0,ncol=3,nrow=4))

(i.e., leaving rawlist as a dataframe) leads to a data frame with only one
row of zeros appended.
