Bucketting data

Hi,

Am sure this is a trivial question but for some reason, haven't been able to figure it out.

I want to bucket data in a vector, and then iterate over the buckets.

Say the data set is:
cleandata[,4]
[1]  26  26  26  26  26  26  26  26  26  26  26  26  61  61  61  61  61  61  61  61  61  61  61  89  89  89  89  89  89  89 180 180 180 180 362 544 544 544
[39] 544 544 544 544 544 544 544

This has the buckets: 

26 61 89 180 362 544

I'd like something which gives me a vector of these buckets, i.e. bucket(cleandata[,4])=vector of 26 61 89 180 362 544

and length(bucket(cleandata[,4]))=6

Thanks,
Tolga

I'm not certain what "buckets" are, but based on your example try
?unique

try this:

unique(cleandata[, 4])
length(unique(cleandata[, 4]))

I hope it helps.

Best,
