[R] "bucketing" observations

[Dan Dube]

is there a better way to bucket observations into more-or-less evenly
sized buckets than this?  it seems like this must be a common operation:

dt = data.frame(points=rnorm(1000),bucket=NA)

breaks = quantile(dt$points,seq(0:1,.1))
for (i in 2:length(breaks)) {
	if (i == 2) {
		ind = which(dt$points >= breaks[i-1] & dt$points <=
breaks[i])
	} else {
		ind = which(dt$points > breaks[i-1] & dt$points <=
breaks[i])
	}
	dt$bucket[ind] = i-1
}

thanks!
