Hi all, I'm kinda new in R programming and I need some help preparing a database to run logistic regression.
I have data in a tuple form: *id cat val* 1 A 2 1 C 4 3 B 1 5 A 2 6 A 3 6 B 5 6 C 2 8 B 5 8 D 2 9 D 3 and would like to have it like: *id catA catB catC catD* 1 2 0 4 0 3 0 1 0 0 5 2 0 0 0 6 3 5 2 0 8 0 5 0 2 9 0 0 0 3 Could someone help me? I have already tried table function, but it doesn't return row and column names. -- View this message in context: http://r.789695.n4.nabble.com/Rows-to-Column-tp4682245.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.
