I want to print a variable with in double quotes.
For example
x = 10 ;
x ; #prints 10

\"x\" ; # Error: unexpected input in "\"
I want to the out put as '10' or "10"
There are lots of ways to do that. The simplest is to convert x to a
character value, and it will automatically print that way:
> x <- 10
> as.character(x)
[1] "10"
A more general way is to use cat(), then you can print whatever you want:
> cat("'", x, "'\n", sep="")
'10'
The obvious disadvantage is that you need to worry about adding a new
line at the end (the \n), and the separator between each thing you're
printing (sep="" says put nothing there, the default is a space).
