stri_split_charclass: Split a String by a Character Class

Description

Splits each element of str into substrings. pattern indicates delimiters that separate the input into fields. The input data between the matches become the fields themselves.

Usage

stri_split_charclass(str, pattern, n_max = -1L, omit_empty = FALSE)

Arguments

str

character vector with strings to search in

pattern

character vector specifying character classes to match, see stringi-search-charclass

n_max

integer vector, maximal number of pieces to return

omit_empty

logical vector; determines whether empty strings should be removed from the result

Value

• Returns a list of character vectors.

Details

Vectorized over str, pattern, n_max, and omit_empty.

If n_max is negative (default), then all pieces are extracted.

omit_empty is applied during the split process: if it is set to TRUE, then empty strings will never appear in the resulting vector.
