I'm still not fully understanding exactly how R is handling data frames, but am getting closer. Any help with this one will likely go a long way in getting me there. Let's say I have a data frame, let's call it "a". Within that data frame i have two variables, let's call them "b" and "c", where "b" is a single numeric value per observation, while "c" is a LIST of numeric values. What I want to be able to do is perform an operation on each element in "c" by the single element in "b".
So, for example, if I wanted to subtract each element in "c" from the scalar in "b". For example, if i had > a$b [1] 1988 [2] 1989 … & > a$c [[1]] [1] 1985 1982 1984 [[2]] [1] 1988 1980 … I'm looking for a result of: a$new [[1]] [1] 3 6 4 [[2]] [1] 1 9 … I've tried a few different things, none of which have the desired result. Any help appreciated. thanks! jimi adams Assistant Professor Department of Sociology American University e: jad...@american.edu w: jimiadams.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
