Hello,
And ?findInterval is faster than hist.
findInterval(x, c(-Inf, 500, 1000, 5000))
Also, before the cut code, the OP wrote
if value is between 1-100 do something
but in the breaks vector there's no 100. I guess this is not important,
though, only the function to bin the data is.
Hope this helps,
Rui Barradas
