Hello,
As for truncation, you can write a one line function:
dec_trunc <- function(x, digits = 0) trunc(x * 10^digits)/10^digits
As for approximation, maybe you're looking for ?signif.
Hope this helps,
Rui Barradas

What is the function to do the truncation to a certain decimal digit of a
number. And the function approximation?
Thanks.
