[R] sprintf doesn't care of escape characters

sprintf is working just fine.  Your problem is the interpretation of
what the results are.  Displaying the object will show the escape
characters, but if you use "cat", or output to a file, you will see
that the result is correct:


> cat( sprintf("a\nb"))
a
b>
> cat(sprintf("a\"bc\"d"))
a"bc"d>
