[R] R intersect()

Hi all, I have the following df: licenseY :int 41006 41013 41044 41046 41067 41166 41202 41262 41274 41290 licenseZ :int 41006 41013 41018 41044 41046 41067 4 41200 41262 41272 I needed the common values in both license columns so I used : intersect(df$licenseY

I see how merge works now, and to answer my own question, I can have any number of columns of miscellaneous information I want. -- View this message in context: http://r.789695.n4.nabble.com/Intersect-2-lists-bring-extra-columns-tp4675136p4675146.html Sent from the R help mailing list archive

Re: [R] Intersect 2 lists+bring extra columns

Hi A.K. That is exactly what I was hoping to do. If you have the time, can you explain what the fruit[,-1] term means in the merge? Also, if I wanted to expand the number of columns to report to include a 4th column, let's call it flavor, how would I go about doing that? J.S. -- View this me

[R] Intersect 2 lists+bring extra columns

Re: [R] intersect() without discarding duplicates?

Try this one liner. The first argument of rep is the sorted intersection and the second argument is the calculated from the parallel minimum of the counts of elements in a that are also in b and the counts of elements in b that are also in a. rep(sort(intersect(a, b)), pmin(table(a[a %in% b]), ta

Thanks, but that doesn't quite work, since I'd want the result of b[b %in% a] to be symmetric with a[a%in%b] (so if there are two 2's in EACH vector, I'll get two 2's in the result, but if there are two 2's in only one vector, but one two in the other, the result will show only one 2. Consider: >
