[R] Windows path backward slash

[Tom Woolman]

In Windows versions of R/RStudio when refering to filename paths, you  
need to either use two "\\" characters instead of one, OR use the  
reverse slash "/" as used in Linux/Unix. It's an unfortunate conflict  
between R and Windows in that a single \ character by itself is  
treated as an escape character.

It's all Microsoft's fault for using the wrong direction slash in  
MS-DOS and not conforming to Unix style c. 1980.
