R devel - Oct 2007 - Inconsistent behavior of sQuote and dQuote

Dear all

When comparing sQuote("text") and dQuote("text") on MacOS X
and Linux FC4
I get an inconsistent behavior (using the new release version R-2.6.0):

sQuote: On Mac I get the correct result "'text'", but on FC4
the
incorrect result "`text?".
dQuote: On Mac I get the correct result "\"text\"", but on
FC4 the
incorrect result ""text"".

For this reason I cannot use these functions in my package.

Best regards
Christian

Those both look correct to me (but not the same).  What do you see?

The second one looks wrong here (no escapes shown), but I suspect those 
inner quotes aren't really the same as the outer quotes, and that's why 
they're not escaped.

If you don't want the fancyquotes at all, you can use 
options(useFancyQuotes=FALSE).  In a package, it would be polite to do 
this only locally, i.e. have something like

save <- options(useFancyQuotes=FALSE)
on.exit(options(save))

in functions that call sQuote or dQuote, because options() belong to the 
user, not to you.
