Different RNG?

[muschellij2]

Is there a call to the system RNG in getASLNoisePredictors somewhere I'm not seeing? It would seem to fail in all Linux builds with the test I have from OSX: https://travis-ci.org/ANTsX/ANTsR/jobs/601412222#L4071 and https://travis-ci.org/muschellij2/ANTsR/jobs/601551393#L4071

Error: `cm` not equal to c(-0.223377249912075, 0.0012754214030999).
2/2 mismatches (average diff: 0.00154)
[1] -0.22310 - -0.22338 == 0.000273
[2]  0.00409 -  0.00128 == 0.002811

I have checked the results on our cluster Centos 7 system and the means are equal. Is this possible to test in your docker image?

OSX on the other hand fails with a different error with abpN4: https://travis-ci.org/muschellij2/ANTsR/jobs/601551397#L6263, which I see

/Users/travis/build/stnava/ITKR/ITKR.Rcheck/00_pkg_src/ITKR/src/itks/Modules/Core/Common/src/itkDataObject.cxx:348:
Requested region is (at least partially) outside the largest possible region.

which I don't know if it's similar to https://github.com/stnava/ITKR/issues/43, but it would seem as though something odd is going on with the ITK build. But my local install of ANTsR using stnava/ITKR@98afc3a works fine with the abpN4 test.

possibly here: https://github.com/ANTsX/ANTsR/blob/master/R/crossvalidatedR2.R#L30

the abpN4 bug should be fixed at least on the master branch - travis tests would fail otherwise.

I don't know if it's a by-product of the binary install. Can you try these examples locally on you machine, or simply run R CMD check on this ANTsR version?

Checks passed fine

Really confused then why it’s failing on travis
