## 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).

           "\\begin{small}Proin nibh augue,\\end{small} suscipit a, scelerisque sed, lacinia in, mi.",
