Statistics for a Character Vector Containing LaTeX Commands

Description

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

Details

We use a slightly modified LaTeX Word Count algorithm taken from Kile 2.1.3, see http://kile.sourceforge.net/team.php for original contributors.

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).
