[R] Generate Random Samples

[Peng Jiang]

Hi,

I am a newbie to R and I am working with a Mac.

Is there any package that I can use to generate random samples from a  
user defined distribution ?  That is , I define a distribution  
function ( maybe multi dimension ) and I want some random samples  
generated from my this distribution.

Or, there is a more specific problem . If I have a three component  
mixture with each of them being normal distribution( say 3  
dimension ) , is there any package that I can use to generate random  
samples from this mixture . I know I can generate random samples from  
each individual component. However, can I just add them directly????

Thanks.
