[R] Estimate LA/AIDS elasticities with Heckman correction in R

[Belinda Archibong]

Hi,

I've been trying to figure out the code to estimate the LA/AIDS model
with the inverse mills ratio from the Heckman-2 step to correct for
zero consumption in R with no luck. Could someone please direct me on
how to do this in R?

Thanks,

Belinda A.
