## R/LaTeX Driver for Sweave

### Description

A driver for `Sweave` that translates R code chunks in LaTeX files.

### Usage

    RweaveLatex()

    RweaveLatexSetup(file, syntax, output = NULL, quiet = FALSE,
                     debug = FALSE, echo = TRUE, eval = TRUE,
                     keep.source = FALSE, split = FALSE, stylepath = TRUE,
                     pdf = TRUE, eps = TRUE)

### Arguments

`file` | Name of Sweave source file.
`syntax` | An object of class `SweaveSyntax`.
`output` | Name of output file, default is to remove extension ‘.nw’, ‘.Rnw’ or ‘.Snw’ and to add extension ‘.tex’. Any directory names in `file` are also removed such that the output is created in the current working directory.
`quiet` | If `TRUE` all progress messages are suppressed.
`debug` | If `TRUE`, input and output of all code chunks is copied to the console.

`stylepath`

If `TRUE`, a hard path to the file ‘Sweave.sty’ installed with this package is set, if `FALSE`, only `\usepackage{Sweave}` is written. The hard path makes the TeX file less portable, but avoids the problem of installing the current version of ‘Sweave.sty’ to some place in your TeX input path. The argument is ignored if a `\usepackage{Sweave}` is already present in the Sweave source file.

`echo` | set default for option `echo`, see details below.
`eval` | set default for option `eval`, see details below.
`keep.source` | set default for option `keep.source`, see details below.
`split` | set default for option `split`, see details below.
`pdf` | set default for option `pdf`, see details below.
`eps` | set default for option `eps`, see details below.

### Supported Options

RweaveLatex supports the following options for code chunks (the values in parentheses show the default values):

echo:
  logical (`TRUE`). Include S code in the output file?
keep.source:
  logical (`FALSE`). When echoing, if `keep.source == TRUE` the original source is copied to the file. Otherwise, deparsed source is echoed.
eval:
  logical (`TRUE`). If `FALSE`, the code chunk is not evaluated, and hence no text or graphical output produced.
results:
  character string (`verbatim`). If `verbatim`, the output of S commands is included in the verbatim-like Soutput environment. If `tex`, the output is taken to be already proper latex markup and included as is. If `hide` then all output is completely suppressed (but the code executed during the weave).
print:
  logical (`FALSE`) If `TRUE`, each expression in the code chunk is wrapped into a `print()` statement before evaluation, such that the values of all expressions become visible.
term:
  logical (`TRUE`). If `TRUE`, visibility of values emulates an interactive R session: values of assignments are not printed, values of single objects are printed. If `FALSE`, output comes only from explicit `print` or `cat` statements.
split:
  logical (`FALSE`). If `TRUE`, text output is written to separate files for each code chunk.
strip.white:
  character string (`false`). If `true`, blank lines at the beginning and end of output are removed. If `all`, then all blank lines are removed from the output.
prefix:
  logical (`TRUE`). If `TRUE` generated filenames of figures and output have a common prefix.
prefix.string:
  a character string, default is the name of the ‘.Snw’ source file.
include:
  logical (`TRUE`), indicating whether input statements for text output and includegraphics statements for figures should be auto-generated. Use `include = FALSE` if the output should appear in a different place than the code chunk (by placing the input line manually).
fig:
  logical (`FALSE`), indicating whether the code chunk produces graphical output. Note that only one figure per code chunk can be processed this way.
eps:
  logical (`TRUE`), indicating whether EPS figures shall be generated. Ignored if `fig = FALSE`.
pdf:
  logical (`TRUE`), indicating whether PDF figures shall be generated. Ignored if `fig = FALSE`.
width:
  numeric (6), width of figures in inch.
height:
  numeric (6), height of figures in inch.
expand:
  logical (`TRUE`). Expand references to other chunks so that only R code appears in the output file. If `FALSE`, the chunk reference (e.g. `<<chunkname>>`) will appear. The `expand=FALSE` option requires `keep.source = TRUE` or it will have no effect.
concordance:
  logical (`FALSE`). Write a concordance file to link the input line numbers to the output line numbers. This is an experimental feature; see the source code for the output format, which is subject to change in future releases.
