Dear R-users,
It is my understanding that cat(shQuote(a.string)) should print the origintal
a.string. Is this right?
I am not sure cat() correctly prints strings which are generated by
triple-shQuote():
> shQuote(shQuote("a"))
[1] "\"\\\"a\\\"\""
> cat(shQuote(shQuote(shQuote("a"))), '\n')
"\"\\"a\\"\<file://\\"a\\"\>""
As you can see the latter string has fewer quoting '\' than the former.
cat() of double shQuote works as expected:
> shQuote("a")
[1] "\"a\""
> cat(shQuote(shQuote("a")), '\n')
"\"a\""
> version

Am I missing something?
