one could also use the "Truncate"-methods of package distr; cf.

If the situation is extreme Peter Daalgard gave some sophisticated code at

Hi all,
I need to create 100 normally distributed random values (X) which can
not exceed a specific range (i.e. 0<X<Y).
With rnorm I cannot specify Max and min values among which values
have to stay, like in runif so does some other simple way exist to do
this with normally distributed random values?
Presumably you want a truncated normal distribution. Duncan Murdoch
posted some neat code on this list, back in the end of July this year,
to generate samples from such a distribution.
