Error: unexpected '}' in "}" in an if loop

I am trying do a for loop with an if statement. It didn't work, so I took out the "if" loop. I made it work. That is, the following code

if (data$mis[3] = "mis") {
print ("George Bush")
   }

Outputs "Geoge Bush"

However, it also says:

Error: unexpected '}' in "}"

Any idea why that might be?
