Brian Ripley told you how to do the translation, but there's another 
problem:

The problem is that you haven't entered a string containing backslashes, 
you've tried to enter a string containing escapes.  The parser sees a 
single backslash and attaches it to the next letter, so \U is taken to 
be the start of a Unicode character, and you get the error

The way around this is to avoid the parser, by something like this:

oldstring <- readline()

C:\Users\Rinker\Desktop\Research&  Law\Data\School Data 09-10


and then applying chartr to oldstring.
