```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]))

Objet: [R]  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], "+",
numbers[j],"=", letters [i+j+k])
dev.off"
>                                      }
Error: unexpected '}' in "                                     }"
>                                }
Error: unexpected '}' in "                               }"
>                            }
Error: unexpected '}' in "                           }"
