You don't need to go that far! Assuming you need to use hist() to construct the counts in the first place, you can then modify the $counts component of what it returns. Here is an example using uniform random data: X <- 5*runif(265) ## Have a look at it: hist(X,breaks=5) ## Now make a histogram with class frequencies divided by the factors: Factor <- c(105,50,60,150,200) H <- hist(X,breaks=5,plot=FALSE) H$counts <- H$counts/Factor plot(H) Is that the sort of thing you were after?
