[R] standardized partial regression coefficients

[Yuval Sapir]

Hi all,
I am relatively new to R, so let me know if I missed something trivial.
I want to perform path-analysis with at least three levels of explaining 
variables (i.e., A affects B that affects C). I perform multiple 
regression for each set of variables, and get estimates for the partial 
coefficients and their SE. How can I translate it to standardized 
partial regression coefficients ("beta" in SPSS)?
Thanks
Yuval
