dividing items into bins and retrieving the counts in each bin

I have a vector of continuous observations like so:

x = c(0,0.001,0.03,0.8,0.005,0.6,0.12,0.3,0.75,0.9,0.043,0.81,0.5,0.21,0.27,0.17,1,0.9)

I divide it to twenty bins like so:

cut(x, breaks=seq(0,1,by=0.05),include.lowest = TRUE)

How do I retrieve the number of elements that "fell" in each bin? For example, how can I tell there are 5 items in the bin [0,0.05]?

Many thanks!!

N.M

Try `table(cut(x, breaks=seq(0,1,by=0.05),include.lowest = TRUE))` – Simon O'Hanlon Jan 13 '14 at 16:29
Thanks but how do I get a vector with these counts? Sorry for the idiotic question... new to R... – N.M Jan 13 '14 at 16:32

It *does* give a vector with those counts. It is a named vector. `res <- table(cut(x, breaks=seq(0,1,by=0.05),include.lowest = TRUE)); attr(res,"names") <- NULL`. – Simon O'Hanlon Jan 13 '14 at 16:33

`dimnames(res) <- NULL` – rawr Jan 13 '14 at 16:36
@rawr thanks, that was what I meant. I was wondering why `names(res)<-NULL` wasn't working – Simon O'Hanlon Jan 13 '14 at 16:37
This worked for me: unname(res) Thanks everybody!! – N.M Jan 13 '14 at 16:38

@SimonO'Hanlon you should probably cut and paste this as an answer so it can be accepted – rrs Jan 13 '14 at 17:11
@rrs I think it a duplicate and should be closed, but I can't be bothered to search for the dupe. Feel free to post it yourself if you want. – Simon O'Hanlon Jan 13 '14 at 17:21
