[Rd] incorrect behaviour of formals (PR#4510)
Full_Name: Jörg Polzehl Version: 1.8.0 OS: Windows XP Submission from: (NULL) (62.141.176.1) I encountered a problem when playing with the mle library and specifying negative starting values for the parameters. The reason seems to be an incorrect behaviour of function formals: glike<-function(a=1,b=1,c=1) a> formals(glike)$a [1] 1 $b [1] 1 $c [1] 1> unlist(formals(glike))a b c 1 1 1> glike<-function(a=1,b=1,c= -1) a > formals(glike)$a [1] 1 $b [1] 1 $c -1> unlist(formals(glike))$a [1] 1 $b [1] 1 $c -1 Regards, Jörg Polzehl PS: The same happens in version 1.7.1
