[R] Simple Binning of Values

[Martin Striz]

Hi, I just joined the list, but here's a suggestion.

x <- c(123, 48, 342, 442, 43, 232, 32, 129, 191, 147)

bins <- as.data.frame(table(cut(x, breaks=c(0, 100, 200, 300, 400, 500),
   labels=c("0-100", "100-200", "200-300", "300-400", "400-500"))))

colnames(bins) <- c("bins", "count")

> bins
     bins count
1   0-100     3
2 100-200     4
3 200-300     1
4 300-400     1
5 400-500     1

Subject: [R] Simple Binning of Values

Hello

I am very new to R.  I have an R task to complete that I have not been
able to find a straightforward answer to as of yet.  I have a list of
values. I would like to count the number of values that are in one
bin, the number that fall in the next bin, etc.

For example

My input file is:  123 48 342 442 43 232 32 129 191 147

I would like the output to be similar to:

0-100 3
100-200 4
200-3001
300-400 1
400-5001


Thus far I have tried working with hist, cut and split, but have not
gotten very far.

Thanks
Kat
