[R] Rounding fractional numbers to nearest fraction

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
