[R] how to call sas in R

[Nongluck Klibbua]

Hello all,
I would like to know how to call sas code in R. Since I simulate data in
R and I need to use sas code (garch-t,egarch and gjr) to estimate it. I
need to simulate 500 times with 2000 obs. How I can call that code in
R.Also, how I can keep the parameters from the estimate.

j=1:500
i=1:2000
sas code
keep parameters.

Best Appreciate,
Luck
