Dear all,
I have defined a generic as.ff(x, ...) and a method as.ff.function(x, ...) which converts a standard R function x into a chunked version operating on large ff objects. Everything works fine, but when registering
S3method("as.ff",function)
in NAMESPACE, the installation fails with some kind of parsing error:
adding build stamp to DESCRIPTION

Is this a bug? Any ideas?
You need to quote "function". It falls under
(Note that variable names may be quoted, and non-standard names such as
@code{[<-.fractions} must be.)
since reserved words cannot be standard names. But it could stand being
spelt out in R-exts.
There are examples in package 'utils'.
