You're right, it's a spurious warning. What causes it is the following line
in findPerl.R in the package gdata (bgafun depends on made4 which depends on
gplots which depends on gdata):
perl.ftype <- shell("ftype perl", intern = TRUE)
This command returns the warning you saw. I don't think it's a reliable way
to check if perl is installed, as it returned nothing even on a system where
perl was installed.
Something about this shell command is screwing up R CMD build and producing
the spurious warning about using \method markup. I'm not sure what the exact
mechanism is, but I can reliably cause it (or eliminate it) by either
leaving that line as is or changing it to
perl.ftype <- ""
There is something weird about the ftype command and the way it interacts
with the shell. If I do:
ftype | more
and press 'q' after the first screenful of info, I see this (many times):
The process tried to write to a nonexistent pipe.
I don't see this behavior with other Windows commands.
I'm not sure if that helps you track this down or not, but that's what I am
able to figure out.
Thanks
