Paul -
    When you print a string, it escapes the quotes with a 
backslash.  That's a property of the print() function,
not the string itself.
    If you want to see the string, use cat().  The nchar()
function is also useful:

> str1 <- '"xyz"'
> qr2 <- paste('abc',str1,sep='')
> print(qr2)
[1] "abc\"xyz\""
> cat(qr2,'\n')
abc"xyz" 
> nchar(qr2)
[1] 8
