Hi,
I seemingly have a simple problem, but I've spend hours reading guides &
posts on this forum and I can't seem to piece together what I need.
I have a dataframe where I want to divide it into two subsets: a sample, and
the remainder of the dataframe in a new frame.
I've tried this:
split(df, sample(nrow(df), size=100, replace=FALSE))
another way would be to make a new dataframe of my sample and (something I
can do in SQL but not R) then select rows that are NOT in the sample
dataframe.
Thanks for any help!
