Hickman models with two binary dependent variables in R

Faradj Koliev 
Hi everyone, 

How do I run Heckman models in R with two binary dependent variables? 

sampleSelection package in R works with standard heckman models ( binary DV for the selection equation and continuous DV for the outcome equation). In my case dependent variables are both binary (actually ordered but I didn?t find anything on that)

So using sampleSelection package one could do this by running: 

SelectionEquation <- binaryDV1 ~ x1+x2+x3+x4

OutcomeEquation <-  binaryDV2~o7+x1+x4+x5

HeckmanModel <- heckit(SelectionEquation,OutcomeEquation, data=mydata, method="2step")


The problem is that heckit() doesn?t work here. I think in STATA one could use heckprob command for this. Anyone who knows more than me? 

Thanks!
