Brian,

Thanks for answering.

good to know that it is done in R-devel

Why then do we have as.character(NA)?
Isn't it standard, that a as.something() function can handle NAs? Isn't it
good style to explicitely use as.something(NA) instead of relying on
auto-coercion? Isn't it a language feature that we can assign NA to any element of a
vector, especially if NA is a legal (creatable) element? 

Puzzled


Jens
