[Rd] namespace crash on S3method("as.ff",function)

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
  installing NAMESPACE file and metadata Fehler in parse(nsFile) : Unerwartetes ')' bei 348:
349: S3method("as.ff",function)
Calls: <Anonymous> -> parseNamespaceFile -> parse Ausf³hrung angehalten
make[2]: *** [nmspace] Error 1
make[1]: *** [all] Error 2
make: *** [pkg-ff] Error 2
*** Installation of ff failed ***

Is this a bug? Any ideas?

Best regards

Jens

P.S. with as.ff() we can do things like
ffx <- as.ff(x) # as.ff.default() turns a standard R object into an ff object stored on disk as.ff(log)(ffx) # as.ff.function() turns 'log' into a function that we can call on ffx: taking the log of an almost arbitrarily large object
