Dear Martin Morgan, thank you very much for your answer that made it clear to me. Since my package is linked to yours by essence, there is no reason to redefine the existing setGeneric functions.
As a summary, if someone is importing functions from another package, he is supposed to know they already exist and shouldn't redefine their generic template. This can sound stupid like that but wasn't clear to me before putting everything in a package. Moreover this situation is not an issue while loading another package that potentially has functions with same names thanks to the Namespaces implicitly encapsulating the packages. Thank you again and I hope the package will be of interest for the community :) Romain. -- View this message in context: http://r.789695.n4.nabble.com/2-setGeneric-s-same-name-different-method-signatures-tp4658570p4659349.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
