Dear R Community, A simple problem (for some of you): I wish to index a data.frame by all elements NOT in my index E.g.: > a<-as.data.frame(matrix(rnorm(100),nrow=10,ncol=10)) > b<-which(a$V1>0.8) > b [1] 1 4 6 10 > a_indexb<-a[b,] > a_notIndexB<-a[!b,] > nrow(a_notIndexB) [1] 0
Indexing a on b is not a problem (a_indexb), but how can do get only the elements left if I take out the elements indexed with b? Thank you and wishing you a great day! Georg. **************************************** Georg Ehret Baltimore, US [[alternative HTML version deleted]] ______________________________________________ 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.
