thanks for the great help! But I have one additional question (hope I can work alone then); I want to replace the values of a vector, like this: x <- c(1,2,2,3,3,4,4,4,5,1) x[x==1] <- c(12) x[x==2] <- c(13) x[x==3] <- c(17) x[x==4] <- c(20) x[x==5] <- c(22) is there a way to do that just in one or two code lines?
recode.mtx <- matrix( c(1,12, 2,13, 3,17, 4,20, 5,22), ncol=2, byrow=TRUE)
# could also use matrix( c(1:5, 12, 13, 17, 20, 22), ncol=2) x <- sapply(x, function(x) recode.mtx[x,2] ) > x [1] 12 13 13 17 17 20 20 20 22 12 -- David Winsemius
I tried x[x == c(1:5)] <- c(12,13,17,20,22) but that makes something totally different ... thanks for any help! ______________________________________________ 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.
