Fortran runtime error: Bad value during integer read #3
Comments
|
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:
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). |
Thanks for providing this package!
I'm trying to run dw-nominate in a setting where there is only a small number of rollcall votes (and relatively small number of legislators). I'm getting an error that says "Fortran runtime error: Bad value during integer read" and am not sure whether it's because of the data constraint, about my session environment, something with the gcc/fortran, or all of these.
I ran these on a mac command-line R. My output and sessionInfo posted below as well. If you could point me towards some direction as to how I might be able to fix this, I'd greatly appreciate it. Thanks!
