Hello I want to make some variables with the ifelse-function, but i don't know how to do it.
I want to make these five variables; b2$PRRSvac <- ifelse(b2$status=='A' | b2$status=='Aa',1,0) b2$PRRSdk <- ifelse(b2$status=='B' | b2$status=='Bb',1,0) b2$sanVac <- ifelse(b2$status=='C' | b2$status=='sanAa',1,0) b2$sanDk <- ifelse(b2$status=='D' | b2$status=='sanBb',1,0) b2$totalvac <- ifelse(b2$status=='San',1,0) And b2$UGT <- ifelse(b2$status=='UGT',1,0) b2$KOM <- ifelse(b2$status=='KOM',1,0) But, as one from this forum told me, it doesn't work because the words is in a wrong format or something like that. I have attached the text-file i've used, and the R-kode. Hope anyone can help me? text-file; http://www.nabble.com/file/p21993098/allesd%2528uden%2Bf%25C3%25B8r%2529060209.txt allesd%28uden+f%C3%B8r%29060209.txt R-kode (just run from line 1-22) ; http://www.nabble.com/file/p21993098/PRRS%2B%2528med%2Ballle%2BSD%2529.r PRRS+%28med+allle+SD%29.r -- View this message in context: http://www.nabble.com/extracting-parts-of-words-or-extraxting-letter-to-use-in-ifelse-func.-tp21993098p21993098.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.
