You can contact the package maintainer (cc'd here) and suggest that the use of:
normalizePath()
be implemented in the code, which would then do tilde expansion, etc. when
relative file paths are passed rather than absolute paths are used.
A workaround for now, would be to wrap your filename in that function in your
code, so that when you use relative paths, the appropriate expansion is used
and passed to the gdata function as the filename argument.
I just made this change myself in the WriteXLS package at the request of
another useR.
