Hello R User, I am new in R and trying to migrate from SAS. I have to convert a table that look like this
YEAR FIRM ID_NAME VALUE 1994 Microsoft John Doe 5 1994 Microsoft Mark Smith 3 1994 Microsoft David Ring 2 In this: YEAR FIRM ID1 vALUE ID2 VALUE 1994 Microsoft John Doe 5 Mark Smith 3 1994 Microsoft John Doe 5 David Ring 2 1994 Microsoft Mark Smith 3 David Ring 2 I have to do it for all the possible pair combination of ID_Name linked to the same firm for any given year in my sample. Do you have any suggestion? Thank you very much, Matteo -- View this message in context: http://r.789695.n4.nabble.com/Data-permutation-tp3085707p3085707.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.
