problem due to version?

[GaioTransposon]

Hi Dosorio,

the last version 2.4.3 is not present on CRAN.

I am using macrel, which depends on peptides and getting this error:

rpy2.rinterface_lib.embedded.RRuntimeError: Error: package or namespace load failed for ‘Peptides’:
 package ‘Peptides’ was installed before R 4.0.0: please re-install it

This problem doesn't get solved after re-installing r-peptides (doing it this way: conda install -c r r-peptides)

Any suggestions?
Kind Regards
Dany

Hi @GaioTransposon,

Thanks for using Peptides. Version 2.4.3 is the current one available at CRAN https://cran.r-project.org/web/packages/Peptides/index.html. Could you please try using install.packages('Peptides') in your R terminal?

Please let us know if it works,

Best wishes,

Daniel

Macrel depends on it, and installs it via conda in an environment. I am not using it directly on R
Would it be still possible to install it via conda?
Best,

UPDATE:
problem was solved by installing macrel within a conda environment that had an R version 3.6 installed (R version 4.0.3 was not liked by r-peptides).
