The following code from Plot a heart in R gives me how to draw hearts, clubs, spaces, and diamonds in R.

clubs <- expression(symbol('\247'))
hearts <- expression(symbol('\251'))
diamonds <- expression(symbol('\250'))
spades <- expression(symbol('\252'))
csymbols <- c(clubs, hearts, diamonds, spades)

plot( 0, xlim=c(0,5), ylim=c(0,2), type="n" )
clr <- c("black", "red", "red", "black") 
for (i in 1:4) {
  hline <- function( yloc, ... ) 
         for (i in 1:length(yloc)) 
             lines( c(-1,6), c(yloc[i],yloc[i]), col="gray")  
              hline(0.9); 
                hline(1.0);
                hline(1.1);
                hline(1.2)  
 text( i, 1, csymbols[i], col=clr[i], cex=5 )  
 text( i, 0.5, csymbols[i], col=clr[i] ) }

The help in symbol lists quite a few more. However, I was wondering how to get the entire list corresponding to the different values in the "\xxx" where xxx are the digits. Any suggestions?

Just to clarify, I am looking for the symbols list corresponding to the different strings. For instance, in the above '\247' corresponds to clubs, '\252' corresponds to spades and so on. I am looking for the entire list of these digits in the character string.

From ?symbol,

The symbol font uses Adobe Symbol encoding

You can find tables of that in several places. When I searched, one of the top results is hosted at R-Core memeber Paul Murrell's page at the Auckland Statistics Dept.
