[R-pkg-devel] loadMethod() not available with Rscript

[Thierry Onkelinx]

Dear Joshua,

Thanks for your prompt reply.

I had a look at all dependencies and none of them use loadMethod(). So
the culprit is probably one of their dependencies.

What would be the best way to deal with this? add library(methods) to
the script or import loadMethod() via the NAMESPACE?

Best regards,
