Your question makes no sense as stated.  However, guessing at what you 
want, you should  perhaps consider the non-central chi-square density with 
1 df and ncp = u/a, i.e,

rchisq(100, df=1, ncp=u/a)

[R] Beta distribution approximate to Normal distribution


I need to generate 1000 numbers from N(u, a^2), however I don't want to 
include 0 and negative values. How can I use beta distribution approximate 
to N(u, a^2) in R.

Thx for help
