I've just filled in any missing values in the legis.data, and it proceeded without the previous error. But now I am getting something else, namely " *** caught segfault *** address 0x7fff2c600d3c, cause 'memory not mapped'". I browsed through stackoverflow and it seems the cause of this type of error can be very diverse..

The NA's are an issue. I didn't think to handle NA values for the legislator data, so I should fix that.
As for the segfault, my first two questions are:
- Did the example with the senate data run for you?
- Are you using gfortran 4.8, as described here?
Assuming the example runs and you installed the package with gfortran 4.8, I can look through the fortran code to try to get an idea of where the segfault occurred. Fair warning though, this can be difficult to debug and I don't know if I will be able to give you the answer or how long it'll take me to find it. (Though I will definitely give it a try because these segfaults annoy me.)
Do you really only have 2 congresses in your data? The DW-NOMINATE fortran code won't estimate a dynamic model unless there are at least 5 congresses, so the results, if it runs, should be nearly identical to W-NOMINATE. The wnominate package is much more stable and mature than this one and I definitely recommend it unless you specifically need to estimate a dynamic model.

Thanks for the quick response!
The senate example did work, but not my own data. And yes, I used gfortran 4.8. But when I used another laptop (also MacOS) later, it did work and gave me output, so it might be that my configuration in this laptop is somehow off.
I currently only have 2 congresses but am in the process of cleaning some more data and adding more. This was more of a learning/trial process for me, and the codes did give me outputs which seems to have some face validity, but as you said they also seem to be very close to W-Nominate. Thanks!

I made a series of commits that should fix the legis.data NA problem, and hopefully a lot of the segfault problems as well, so I'm going to mark this as closed (unless you find that it still isn't working).
