So, after banging my head against the computer for two days now, I still remain clueless as to why this is happening. I was wondering if somebody had an explanation to why this happens? That will be very helpful.

You are misspelling the gsub function name. You are not describing your process with enough detail to replicate it. You are using packages that you are not naming. I suspect you are using gsub with an item of a class for which it was never intended. Consider this:
> mydf <- data.frame(a=c("this is a test", "another test"), b=c("athird", "a fourth"))
> gsub("test","tester", mydf)
 "c(2, 1)" "c(2, 1)"
