Statistics for a Character Vector Containing LaTeX Commands

This function gives LaTeX-oriented statistics for a character vector, e.g., obtained by loading a text file with the readLines function, where each text line is represented by a separate string.

Usage

stri_stats_latex(str)

Arguments

str

character vector to be aggregated

Value

Returns an integer vector with the following named elements:

1. CharsWord - number of word characters;

2. CharsCmdEnvir - command and words characters;

3. CharsWhite - LaTeX white spaces, including { and } in some contexts;

4. Words - number of words;

5. Cmds - number of commands;

6. Envirs - number of environments;

7. ... (Other stuff that may appear in future releases of stringi).

Details

We use a slightly modified LaTeX Word Count algorithm implemented in Kile 2.1.3, see https://kile.sourceforge.io/team.php for the original contributors.
