Now that's odd:

> f<-function(a){
+ return ( log(a) )
+ }
> f("A")
Error in log(x) : Non-numeric argument to mathematical function
> traceback()
2: log(a)
1: f("A")
> try(f("A"))
Error in log(x) : Non-numeric argument to mathematical function
> traceback()
2: log(a)
1: f("A")

and that's with an alpha version from this Tuesday:

R : Copyright 2004, The R Foundation for Statistical Computing
Version 1.9.0 alpha (2004-03-08), ISBN 3-900051-00-3

did we accidentally revert something or what's up?
