strip(x, char.keep = "~~", digit.remove = TRUE, apostrophe.remove = TRUE, lower.case = TRUE)
strip should keep. The default is to strip every symbol
except apostrophes and a double tilde "~~". The double tilde
"~~" is included for a convenient means of keeping word groups
together in functions that split text apart based on spaces. To remove
double tildes "~~" set char.keep to NULL.TRUE strips digits from the text.TRUE removes apostrophes from
the output.TRUE forces all alpha characters to
lower case.Returns a vector of text that has been stripped of unwanted characters.
Strip text of unwanted characters.
