[R] Simple Binning of Values

[arun]

Hi Kat,

Try this:

 x1<-c(123, 48, 342, 442, 43, 232, 32, 129, 191, 147)


  res<-cut(x1,breaks=seq(0,500,by=100))
library(reshape)
 res2<-melt(table(res))
 colnames(res2)<-c("bin","count")
> res2
        bin count
1   (0,100]     3
2 (100,200]     4
3 (200,300]     1
4 (300,400]     1
5 (400,500]     1

I am trying to figure out how to get rid of the brackets.  Otherwise, the results looks fine.

A.K.

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
