data.frame indexing
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.
