R help - Oct 2009 - Problems with code containing a for loop

The following code isn't working and we can't figure out why..

letters =
c("A","B","C","D","E","F","G","H","I","J")
numbers = 1:3 
 
for(i in 1:6){                       #6 letters
                for (j in 1:3) {                   #3 numbers 
                    for (k in -1:1) {             #answer -1,right or +1
                          fn = paste (i,j,k,".bmp",sep="")
                          bmp(file = fn)
                          plot(x = 10, y = 10, ylim=c(0,1), xlim=c(0,1),
axes=FALSE, ylab="", xlab="") 
                          text(0.5,0.5, text = paste(letters[i], "+",
numbers[j],"=", letters [i+j+k]) 
                          dev.off()
                                     }
                               }
                           }

We get the following errors: 
Error: unexpected symbol in:
"                          text(0.5,0.5, text = paste(letters[i],
"+",

                          dev.off"
>                                      }
Error: unexpected '}' in "

Error: unexpected '}' in "

>                            }
Error: unexpected '}' in "                           }"

Because you missed your closing parens in the "text" function call.
The closing parens is closing the "paste" function, you need one more.
I don't know what you're trying to do here, but I am guessing
there's a faster way?

A parenthesis is missing. You can figure that out easily watching the first
error.

text(0.5,0.5, text = paste(letters[i], "+", numbers[j],"=",
letters [i+j+k]))

The following code isn't working and we can't figure out why..

letters =
c("A","B","C","D","E","F","G","H","I","J")
numbers = 1:3 
 
for(i in 1:6){                       #6 letters
                for (j in 1:3) {                   #3 numbers 
                    for (k in -1:1) {             #answer -1,right or +1
                          fn = paste (i,j,k,".bmp",sep="")
                          bmp(file = fn)
                          plot(x = 10, y = 10, ylim=c(0,1), xlim=c(0,1),
axes=FALSE, ylab="", xlab="") 
                          text(0.5,0.5, text = paste(letters[i], "+",
numbers[j],"=", letters [i+j+k]) 
                          dev.off()
                                     }
                               }
                           }

We get the following errors:
