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 " }"
