The error message you are getting makes it rather clear what the
problem is.
R is unable to find the function 'hasArg'. As the hasArg function is
part
of the package 'methods', a solution would be to put require(methods)
at the
beginning of your script.

But I think the idea will be to import(methods) in HydroGOF, since the
package requires these imports to function properly, and import'ing will
mean that hasArg does not have to be found on the (user-controlled)
search path.

Thank you very much for your help.

I have already tried import(methods) in the NAMESPACE of hydroGOF,
however, I got the following error message when doing R CMD check:

checking package dependencies ... ERROR
Namespace dependency not required: ?methods?

So it seems that is not possible to force a package to import 'methods'.

Regarding the Dirk's comment, could it be possible to revisit the
decision about loading 'methods' in in Rscript ?. BTW, I do not know who
is responsible for Rscript...


Thanks in advance,
