Hi Lisa,
Here is one way (if i am right in what is a cumulative histogram), using the
existing possibilities
cumhist <- function(x, plot=TRUE, ...){
h <- hist(x, plot=FALSE, ...)
h$counts <- cumsum(h$counts)
h$density <- cumsum(h$density)
h$itensities <- cumsum(h$itensities)
if(plot)
plot(h)
h
}
R> x <- rnorm(100)
R> cumhist(x)
R> # hist(x, add=TRUE, col="cyan")
R> # if you want to overlay the original histogram
