R help - Sep 2009 - How to print a variable with in double quotes

I want to print a variable with in double quotes.
 For example

x = 10 ;
x  ;    #prints 10
"x" ;  #prints x
\"x\" ; # Error: unexpected input in "\"

I want to the out put as    '10'  or "10"

Thank you

Hi,

Try this,

 x = 10
 noquote(dQuote(x))
 noquote(sQuote(x))

do you mean something like this:

x <- 10
as.character(x)


I hope it helps.

Best,

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).
