Subject: [Rd] [DOC] as.call (PR#1437)
Message-ID: <200204051528.RAA09753@pubhealth.ku.dk>


While I remember this:

The help page for call/as.call/is.call says

     It is not possible to coerce objects to mode call (objects either
     are calls or they are not calls).  `as.call' returns its argument
     if it is a call and otherwise terminates with an error message.

which actually has been untrue for quite a while, e.g.:

> cl<-as.call(c(ls, list("package:base", pattern="obj")))
> eval(cl)
[1] "is.object"    "objects"      "object.size"  "objWithClass"

Someone changed the code without editing the documentation. I know who
the guilty party is and will force him to rewrite the help entry in
due course...
