Map character to integer.

1	char2int(v)

`v`	A character vector.

Maps a character vector to an integer vector. Strings are mapped to integers in the order that they are encountered, as enumerated from the beginning of the input vector. All occurances of a given string are mapped to the same integer. Integer enumeration spans 1:n, where n == length(unique(v)).
