[R] Bug in formals<-

[Frank E Harrell Jr]

I think this is new since a previous version of R:

 > h <- function(x, trantab) trantab[x]
 > w <- 6:4
 > names(w) <- c('cat','dog','giraffe')
 > w
     cat     dog giraffe
       6       5       4
 >
 > formals(h) <- list(x=numeric(0), trantab=w)
 > h
function (x = numeric(0), trantab = c(6, 5, 4))
trantab[x]

You can see that the names have been dropped from trantab's default 
values.  I don't see a workaround but it seems to need fixing.
