generic '[' for a non-exported class
Hi all, I define a S4 class 'foo'. I define '[' and '[<-' for it. I do not want to export foo, so I do not put it in NAMESPACE. I do not want to export '[' and '[<-' either (since the user can not use foo, no raison to give him access to '[' for foo). But R CMD check does not agree with me and report an error: Undocumented S4 methods: generic '[' and siglist 'foo' generic '[<-' and siglist 'foo' Any solution ? Christophe
