[R] Looking for R Equivalent of Gauss Statements

Hi,
I am translating some Gauss code to R. Gauss has an interesting way of
handling constraints. Observe the following code snipplet:
e1 = x[.,23] .eq 0; @ remove obs with Regular Hours = 0 @
e2 = x[.,12] .gt 1; @ remove obs with non-regular work status @
e3 = x[.,4] .lt 15; @ remove obs with agricultural and mining
industry code (< 15)@
esum = e1 + e2 + e3;
e = esum .gt 0; @ remove obs that fail all three of the above
tests @
x = delif(x,e);
I'm hoping that the above is self explanatory. Currently I am using
the "subset" command in R to compute e1, e2, e3 but the rest is
tricky: the actual code has several additional constraints and I'm
ending up with some very ugly buggy code. Is there a straightforward
way to do this in R?
Thanks,
-Francisco
