Hello, There _is_ a function ?within. Maybe your function can be named 'between'

I want to cont how many times a number say 12 lies in the interval. Can anyone assist?Has anyone else ever wished there was a moderately general 'inside' or 'within' function in R for this problem? For example, something that behaves more or less like within <- function(x, interval=NULL, closed=c(TRUE, TRUE), lower=min(interval), upper=max(interval)) { #interval must be a length 2 vector #closed is taken in the order (lower, upper) #lower and upper may be vectors and will be recycled (by "<" etc) if not of length length(x) low.comp <- if(closed[1]) "<=" else "<" high.comp <- if(closed[2]) ">=" else ">" do.call(low.comp, list(lower, x)) & do.call(high.comp, list(upper, x)) } #Examples within(1:5, c(2,4)) within(1:5, c(2,4), closed=c(FALSE, TRUE)) within(1:5, lower=5:1, upper=10:14) S Ellison LGC ******************************************************************* This email and any attachments are confidential.
