R help - Apr 2005 - 'skewing' a normal random variable

Hi All;
The following question is directed more to statisticians on the list.
Suppose I have a normal random variable. Is there a transformation that I
can apply so that the new variable is slightly positively skewed. 
I greatly appreciate your help.

look at the sn package on CRAN --- skew normal distributions, m
and the web page of its author.

I think the box.cox function in package car can do this.

x <- rnorm(1000)
hist(x)
library(car)
hist(box.cox(x, p=0.5))

Play around with different powers.

Best,
