R help - Jan 2001 - By which function I can limit the precision of numbers??

Hi!
I want to plot some numerical results in a graphic. I use the function
text(x,y, result).
What i want is to limit the precision of the numbers stored in result to
2 decimal places for layout reasons. How to do it??
thx Witek

Use the function round(), e.g.:

[1] 3,141593
