I know this is easy, but I am stumped:gsub("0","K","8.00+00")[1] "8.KK+KK"gsub("+","K","8.00+00")Error in gsub("+", "K", "8.00+00") : invalid regular expression '+' In addition: Warning message: In gsub("+", "K", "8.00+00") : regcomp error: 'Invalid preceding regular expression' I don't understand the error message. How do I go about replacing the "+" in the string "8.00+00" with another character?
+ has a special meaning in regular expressions gsub( "[+]", "K", "8.00+00" ) gsub( "\\+", "K", "8.00+00" ) gsub( "+", "K", "8.00+00", fixed = TRUE ) see ?regex for details
