# stri_stats_latex: 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`](https://stat.ethz.ch/R-manual/R-devel/library/base/html/readLines.html) function, where each text line is represented by a separate string.

## Usage

``` r
stri_stats_latex(str)
```

## Arguments

|       |                                   |
|-------|-----------------------------------|
| `str` | character vector to be aggregated |

## 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.

## 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 <span class="pkg">stringi</span>).
