Subject: [Rd] argument names in generic print functions (PR#955)
Message-ID: <200105282349.BAA14358@pubhealth.ku.dk>

Hello,

I think this is a bug, although it is possible that I'm doind something
silly.

I want to be able to determine the argument name for variables passed to
a generic print function

suppose we have

print.foo <- function(x, ...)
{
nm<-deparse(substitute(x))
cat("param name is ", nm, "\n")
}

d<-structure(1, class="foo")

Under R-1.2.[2,3]

> print(d)
param name is  d 

> d
param name is  structure(1, class = "foo") 


Under Splus 3.4 the responses are

> d<-structure(1, class="foo")
> d
param name is  d 
> print(d)
param name is  d 


If I'm going about this the wrong way then please let me know.

Thanks
