QUESTION
I am trying to run a multinomial inverse regression as described here. The R package is called textir
. It works just fine, but I am unable to map the parameters in the R package (called "nlambda" and "gamma") to (what I understand) are hyper parameters of the model as described in the paper (shape and scale parameters r and s of the gamma-hyperprior for each lambda).

"Versions 2+ make [..] differ from [...] original MNIR: penalties are chosen from full regularization paths (instead of being fixed)...". In case anyone else runs in the same problem, one can download version 1.8.8 from github and manually install. It will them work just fine.

to set the names. But note that the number of values in the column and rows names must match the number of columns and rows in the Matrix. In your example, you created a matrix with nrow=3, ncol=2
but then you have a columns
vector of length 3 and a rows
one of length 2.
Here's an example that works
