Maybe you can use "round" and "trunc" functions
For example if you have a vector like this:
x<- c(3.000 3.125 3.250 3.375 3.500 3.625 3.750 3.875 4.000)
and you want to round the numbers to 2 decimals you can use:
round(x,2)
[1] 3.00 3.12 3.25 3.38 3.50 3.62 3.75 3.88 4.00
if you want a n
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,
