Description Usage Arguments Details Examples

This function takes a character string and recodes it. Default recoding functions are available in functions such as tc_recode_vehicle_type() and tc_recode_casualties.

1	tc_recode(x, pattern = NULL, pattern_match = NULL)

`x`	Character string to recode
`pattern`	A named character vector with values representing new values. Has the form `c("Car long name" = "Car", "Taxi/Private hire car" = "Taxi")`. `Car long name` will be converted into `Car` in this case.
`pattern_match`	Character string in the form of `c("car" = "car", "bike" = "bike")` that replaces all parts of the match.

It is based on the function stringr::str_replace_all().

x = c("car long name", "bus", "a bike long", "a bike")
tc_recode(x, pattern = c("car.+" = "car"))
tc_recode(x, pattern = c(".+bike.+" = "bike"))
tc_recode(x, pattern = c("car.+" = "car", ".+bike.+" = "bike"))
tc_recode(x, pattern_match = c("car" = "car", "bike" = "bike"))
