dec <- dec * 4 dec <- round(dec, 0) dec <- dec / 4 dec

}

...but it looks like as.integer(x.1*4)/4 or (round(x.1*4,0))/4 might be easier...

**>Hi all,
**>
**>I've got a matrix of fractional data that is all positive and greater than
**>zero that I would like to "loosely" classify, for lack of a better word. It
**>
**>looks something like this :
**>
**>1.07 1.11 1.27 1.59 0.97 0.76
**>2.23 0.98 0.71 0.88 1.19 1.02
**>
**>
**>What I'm looking for is a way to round these numbers to the nearest 0.25,
**>i.e. the above matrix would be transformed to :
**>
**>1.00 1.00 1.25 1.50 1.00 0.75
**>2.25 1.00 0.75 1.00 1.25 1.00
**>
**>
**>Anyone have a clever way to do this??
**>
**>Thanks in advance,
**>Ken
