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.
For whatever reason, loading R via Rscript does not load the base package "methods" whereas loading the R console does. I'm not entirely sure why this is the case, and I'm sure someone who knows more about the differences between the two could chime in here. -- View this message in context: http://r.789695.n4.nabble.com/Dependency-problem-for-hasArg-tp4635147p4635158.html Sent from the R devel mailing list archive at Nabble.com. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
