installation error

[TahneeMa]

Hi, when trying to install lemur I got the following error: Error: object ‘vars’ is not exported by 'namespace:glmGamPoi' Execution halted ERROR: lazy loading failed for package ‘lemur’

I think it might have to do with packages previously installed that are not compatible?

Hey, thanks for reporting the issue. I assume that you are using glmGamPoi version 1.9 or 1.10? lemur is using the pseudobulk function from glmGamPoi which I only added recently in the development version. Can you see if installing glmGamPoi from Github fixes the issue?

devtools::install_github("const-ae/glmGamPoi")

Hi, thank you! I tried as I saw something similar in previous issues but then got a completely different error:

ld: warning: directory not found for option '-L/usr/local/gfortran/lib'
ld: library not found for -lgfortran
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [glmGamPoi.so] Error 1
ERROR: compilation failed for package ‘glmGamPoi’

* restoring previous ‘/Library/Frameworks/R.framework/Versions/4.2/Resources/library/glmGamPoi’ ```

Sorry for the tedious experience and thank you so much for giving my packages a try. This is really valuable feedback that will hopefully make things easier for everyone in the future.

I have already adapted the DESCRIPTION to state the minimum required version of glmGamPoi and amended the README with a note that one needs to install glmGamPoi from source.

I am surprised by the error message, because glmGamPoi does not contain Fortran code. But anyways, could you maybe try to follow the advice on https://mac.r-project.org/tools/ to install the GNU Fortran compiler? (Based on the error message I assume that you are using a mac, right?)
