[R] sprintf doesn't care of escape characters

[Jeff Newmiller]

I am unable to determine what you think the problem is from your description.

A wild guess is that you just don't know what you are looking at in the output. Do you understand the difference between the output of the "print" function and of the "cat" function? Try

cat( sprintf("a\"bc\"d") )

and

print ( sprintf("a\"bc\"d") )

In a nutshell, print makes the string suitable for inclusion in source code, while cat sends the string directly as-is.
