me again, new to R, haven't programmed in a long time at all sorry to ask what is probably basic a while ago i asked how to remove an element from a list apparently what i am using is not a list but a vector, didn't realize there was a list data type could also use a matrix for what i am doing, is there a way to remove single elements from either of those? thanks for any help, if i was actually using a list as i said last time, the answers i received would have cleared things right up
You can use negative indices to remove entries from a vector; for example, > v <- 1:10 > v[-5] [1] 1 2 3 4 6 7 8 9 10 > v[-c(3,6)] [1] 1 2 4 5 7 8 9 10 Removing single elements from a matrix doesn't make sense -- what goes in the hole? You can, however, remove entire rows or columns with negative indices. (Indexing is discussed in all of the basic introductions to R and S of which I'm aware. It probably makes sense to read one of these -- you'll save time in the long run.) I hope that this helps, John -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
