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!

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

Since you say you
Thanks!
In my case, I need to deal with a lot of such results, e.g. elements in a
matrix. If using sprintf, does it mean I have to apply to each result
individually? Is it possible to do it in a single command?

It all depends on what you want to do with the result. Here are some
variations:
x - matrix(runif(16), 4)
x
[,1] [,2] [,3] [,4]
[1,] 0.2655087 0.2016819 0.62911404 0.6870228
[2,] 0.3721239 0.8983897 0.06178627 0.3841037
[3,] 0.5728534 0.9446753 0.20597457 0.7698414

Thanks to all of you!
Yes, I am generating a latex table in my report.

Yes, in various ways depending on how you

My mistake. I thought your concern was for the quality of the software
(quality of course being defined by a certain committee of one). But it

This happens also when you use C's fprintf and sprintf (at any rate
in my gcc):
r's printing routines (e.g., print, sprintf, cat, anything else?) seem
to rely on the underlying c sprintf, with no prior r-implemented
rounding. hence they import into r whatever
