signif(c(pi,exp(1)), 3)
?signif # and others in that page

Depending on what you want to do, use 'sprintf':
x <- 1.23456789
x
[1] 1.234568
as.character(x)
[1] "1.23456789"
sprintf("%.1f %.3f %.5f", x,x,x)
[1] "1.2 1.235 1.23457"

Hi,
I was wondering how to specify the number of decimal numbers in my
computation using R? I have too many decimal numbers for my result,
when I
convert them to string with as.character, the string will be too
long.
Thanks and regards!
