# Alternative to VGAM for Zero Truncated Negativ Binomial GLM in R

Is there an alternative to the vgam Package to do a zero truncated negativ Binomial GLM in R?

I think the answer is "no". countreg does zero-inflated and zero-truncated count distributions, but only Poisson and NB. actuar gives pdf, cdf, et cetera, but doesn't do regression.
