Doing the following
library(methods)
setGeneric("foo", function(x) standardGeneric("foo"))
setMethod("foo", "ANY", function(x) cat(x))
fails with
Error in while (value[n] == "ANY") n <- n - 1 :
missing value where logical needed
It looks like the line
while (value[n] == "ANY") n <- n - 1
in the source for matchSignature() should be
while (n > 0 && value[n] == "ANY") n <- n - 1
FYI: I tried my suggested modification at it seems to work.
Yes, thanks, that's correct. It had been fixed in r-patched and r-devel, but too late for 1.4.1.
