Either backslash the square brackets, as they have a special meaning
(character range) in regular expressions, or use the fixed=TRUE argument to
indicate that your pattern is not a regular expression.
> gsub("\\[NA\\]NA%", "", "[NA]NA%abcde")
[1] "abcde"
> gsub("[NA]NA%", "", "[NA]NA%abcde", fixed=TRUE)
[1] "abcde"
Your original code would replace ANA% or NNA% with a blank.
> gsub("[NA]NA%", "", c("NNA%abcde", "ANA%abcde"))
[1] "abcde" "abcde"
