Computer-specific model selection results

Most strange -- RMark code apparently working fine EXCEPT for the AIC table results for this particular data set -- results (table / model ranks) are consistent among my laptop and my grad student’s two computers – HOWEVER, my office computer returns a different table (different model ranks) – despite having used the SAME script, SAME data set, from SAME thumb drive! Very strange! Is this cosmic interference from the eclipse?! Any advice appreciated.

Do all have the same version of MARK and RMark? Did you use same version of R - 64 vs 32? If you use R64, it uses Mark64 and if you use R32 it uses Mark32. You didn't give much detail as to the differences but I'd start with the above for starters.

Thanks much for the reply. Both my grad student's and my version's of MARK are 64, R is 64, and to double check with "R.version$system" at the Console prompt we get:
[1] "x86_64, mingw32"
Not sure what "mingw32" (not 32-bit?) means but both of our computers return this output.
Upon re-installing the RMark package we get:
There is a binary version available but the source version is later:
binary source needs_compilation
RMark 2.2.2 2.2.4 FALSE
installing the source package ‘RMark’
trying URL 'https://cran.rstudio.com/src/contrib/RMark_2.2.4.tar.gz'

...HOWEVER, my grad student did NOT get the output behind the asterisks above. Her output only reads:
package 'RMark' was successfully unpacked and MD5 sums checked
...but we both appear to be using RMark 2.2.4.
So appears that all are 64-bit. Both of our Operating Systems are 64-bit as well. The AICc ranks from the two machines are different as are the individual model estimates.

Do u all have the same version of Mark? If the answer is yes, I'm not sure what to tell you. Are all models different or just some? You'll have to do some sleuthing. It is not likely this is an RMARK problem.

Same version of Mark. All model estimates differ. Not explained by Windows 7 vs. 10 operating systems. I'm at a loss. Will try re-loading Mark and R.

wjensen1,
If you don't have any luck with the reinstall, send your RMark code/data offlist to me (
bret@lsu.edu) and I will run in through the various set ups Windows/Linux/R/Mark I have here and see if I can help you identify the issue.
If you can sent the MARK output files for the run on your computer and your grad students that would help as well.
\bret

Thanks Jeff and Bret! Reloaded Mark and R and now have results that are consistent with my our other machines. Not sure what bug made the mess.
