Hi, I have a question about the data handling. I have a dataset as following: ID snp1 snp2 snp3 1001 0/0 1/1 1/1 1002 2/2 3/3 1/1 1003 4/4 3/3 2/2
I want to convert the dataset to the following format: ID snp1 snp2 snp3 1001 00 AA AA 1002 GG CC AA 1003 TT CC GG thing to be done: 1) take the '/' off 2) replace the numbers with letters, 0 not change. 1=A, 2=G, 3=C, 4=T what is the most efficient way to do it? thanks you very much, karena -- View this message in context: http://r.789695.n4.nabble.com/questions-about-string-handling-tp2314335p2314335.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ [email protected] 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.
