Hello,
Try the following.
classes <- function(x, n){
n*findInterval(x, seq(0, ceiling(max(x)), by = n))
}
c4 <- classes(d, 4)
table(c4)
sum(table(c4))
Happy new year,

Dear R users,
I want to group numerical values in classes with different size and count
the values for each classes.
My data is in this forma:
d 15 12,5 30,4 20,5 80,4 100,5 8,2 40,5 33 21 11
And I want the group them in classes with 4 (5,....etc) cm size like this:
class d 16 16 32 24 84 104 12 44 36 24 12
and final to count values for each class:
class d n 12 2 16 2 24 2 32 1 36 1 44 1
84 1 104 1 Total 11
Thank you!
