Hi there, I wish to merge a common variable between a list and a data.frame & return rows via the data.frame where there is NO match. Here are some details:
The list, where the variable/col.name = CLAIM_NO CLAIM_NO 20 83 1440 4439 7002 ... > dim(hrc78_clm_no) [1] 6678 1 The data.frame, where there exists a variable with the same name, CLAIM_NO. > dim(bestPartAreadmin) [1] 13068 93 I wish to merge the two together & only return a data.frame where there is NO match in the CLAIM_NO between both files. I've read & tried code via the "merge" function. If "merge" can do this, I'm missing something with the available options. I'm figuring something like: clm_no_nomatch <- merge(hrc78_clm_no, bestPartAreadmin, by = "CLAIM_NO", .. .. ..) Your help is most appreciated! -- View this message in context: http://r.789695.n4.nabble.com/Merge-function-Return-NON-matches-tp4590755p4590755.html Sent from the R help mailing list archive at Nabble.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.
