| Title: | R Graphics Output in LaTeX Format |
|---|---|
| Description: | Provides a graphics output device for R that records plots in a LaTeX-friendly format. The device transforms plotting commands issued by R functions into LaTeX code blocks. When included in a LaTeX document, these blocks are interpreted with the help of 'TikZ'---a graphics package for TeX and friends written by Till Tantau. Using the 'tikzDevice', the text of R plots can contain LaTeX commands such as mathematical formula. The device also allows arbitrary LaTeX code to be inserted into the output stream. |

The tikzDevice package implements the tikz() ouput device which
generates R graphics in a LaTeX friendly format. LaTeX handles the
typesetting of all text in graphics generated by tikz. This allows for
seamless integration between these graphics and documents that are also being
typeset by LaTeX. Using LaTeX to generate graph text also means that
LaTeX mathematics can be typeset directly into labels and
annotations.
The tikzDevice package
is currently influenced by a number of global options that may be set in
scripts, from the console or in a .Rprofile file. All of the options
can be set by using options(<option> = <value>). These options
allow for the use of custom documentclass declarations, LaTeX
packages, and typesetting engines (e.g. XeLaTeX or LuaLaTeX). The defaults,
if are any for a given option, are shown below the description. The global
options are:
tikzDefaultEngine Specifies which typesetting engine
functions in the tikzDevice package will prefer. Current possible values
are pdftex, xetex or luatex. Respectively, these
values trigger the use of the pdflatex, xelatex and
lualatex compilers.
tikzLatex Specifies the location of the LaTeX compiler to be
used by tikzDevice. Setting this option may help the package locate a
missing compiler. The default is searched for when the package is loaded,
otherwise it can be set manually. This option may be set as follows:
options( tikzLatex = '/path/to/latex/compiler' ).
tikzXelatex Functions similar to tikzLatex, except
this option specifies the location of the XeLaTeX compiler.
tikzLualatex Functions similar to tikzLatex, except
this option specifies the location of the LuaLaTeX compiler.
tikzMetricsDictionary When using the graphics device
provided by tikzDevice, you may notice that appears to "lag" or
"hang" when commands such as plot() are executed. This is because
the device must query the LaTeX compiler for string widths and font
metrics. For a normal plot, this may happen dozens or hundreds of times-
hence becomes unresponsive for a while. The good news is that the
tikz() code is designed to cache the results of these
computations so they need only be performed once for each string or
character. By default, these values are stored in a temporary cache file
which is deleted when is shut down. A location for a permanent cache file
may be specified by setting the value of tikzMetricsDictionary in
.Rprofile with options(tikzMetricsDictionary = '/path/to/dictionary/location').
tikzDocumentDeclaration A string. The LaTeX documentclass
declaration used in output files when standAlone == TRUE.
tikzDocumentDeclaration also influences the calculation of font
metrics. The default value is: options(tikzDocumentDeclaration =
"\\documentclass[10pt]{article}")
tikzLatexPackages A character vector. These are the packages
which are included when using the pdftex engine and
tikz() is used with the the standAlone option as well as
when font metrics are calculated.
tikzXelatexPackages This option works like
tikzLatexPackages, except is is used when the xetex engine is
in use.
tikzLualatexPackages This option works like
tikzXelatexPackages, except is is used when the luatex engine
is in use.
tikzFooter A character vector. The footer to be used only
when standAlone==TRUE.
tikzMetricPackages A character vector. These are the
packages which are additionally loaded when doing font metric calculations.
As you see below, the font encoding is set to Type 1. This is very
important so that character codes of LaTeX and match up. The default value
is: options(tikzMetricPackages = c( "\\usepackage[utf8]{inputenc}",
"\\usepackage[T1]{fontenc}", "\\usetikzlibrary{calc}" ))
tikzUnicodeMetricPackages This vector is used when font
metric calculations are performed using the xetex or luatex
engines. It should have the same contents as tikzMetricPackages with
the addition of the fontspec and xunicode packages.
tikzSanitizeCharacters A character vector of special latex
characters to replace. These values should correspond to the replacement
values from the tikzReplacementCharacters option. See
sanitizeTexString() for more details.
tikzReplacementCharacters A character vector of replacements
for special latex characters. These values should correspond to the values
from the tikzSanitizeCharacters option.
tikzLwdUnit A numeric that denotes the number of pts in LaTeX that lwd=1 in R is
translated to. Defaults to 0.4 (LaTeX and TikZ default); for compatibility
with R default, please use 72.27/96 (96 pixels in R is 1 inch, which is 72.27
points in TeX).
tikzPdftexWarnUTF A TRUE/FALSE value that controls
whether warnings are printed if Unicode characters are sent to a device
using the pdftex engine.
tikzSymbolicColorsA logical value indicating whether colors are written as RGB values or as symbolic names in which case the need to be defined in the LaTeX document.
tikzMaxSymbolicColors an integer number indicating the
maximal number of distinct colors to write symbolically. Any excess color
will be defined as if symbolicColors was set to FALSE.
Default values for all options may be viewed or restored using the
setTikzDefaults() function.
See packageDescription("tikzDevice").

These functions are used internally by the tikz device for proper
string placement in graphics. Both functions check to see if metrics exist
in a global or temporary dictionary (as defined in
options('tikzMetricsDictionary')) and if so will pull the metrics
from there. If the dictionary does not exist, then a temporary one is
created for the current R session. Metrics are calculated via system
calls to LaTeX compilers. Querying compilers to calculate metrics is
expensive and so we strongly recommend setting
options('tikzMetricsDictionary') <- '/path/to/dictionary' to create a
global dictionary.

sanitizeTexString() searches character by character through a string
replacing each occurrence of a special character contained in
strip[i] with the corresponding replacement value in
replacement[i]. tikzDevice calls back this function for every piece
of text when the sanitize option is TRUE. See tikz() for more
information on the default special characters and replacement values.

The TikZ device enables LaTeX-ready output from graphics functions. This is
done by encoding graphics commands using TikZ markup. All text in a graphic
output with tikz will be typeset by LaTeX and therefore will match
whatever fonts are currently used in the document. This also means that
LaTeX mathematics can be typeset directly into labels and
annotations.
The TikZ device currently supports three modes of output depending on the
value of the standAlone and bareBones arguments. If
standAlone and bareBones are set to the default value of
FALSE, the resulting file will only contain graphics output wrapped
in a LaTeX tikzpicture environment. Since this file is not a
complete LaTeX document, it will need to be included in another LaTeX
document using the \\input command. For example:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{figure}
\centering
\input{Rplots.tex}
\caption{}
\end{figure}
\end{document}
When standAlone is set to TRUE, the device wraps the
tikzpicture environment in a complete LaTeX document suitable for
direct compilation. In this mode the preview package is used to crop
the resulting output to the bounding box of the graphic.
When bareBones is set to TRUE, the output is not wrapped in a
document or a tikzpicture environment. This is useful for embedding
an generated graphic within an existing TikZ picture.
In cases where both standAlone and bareBones have been set to
TRUE, the standAlone option will take precedence.
When the option symbolicColors is set to TRUE, the colors will
be written as symbolic names, e.g. red, gray90 and similar. If the
color is not mapped to a symbolic name in R, the color will be named
XXXXX when #XXXXXX is its hexadecimal color. All the color
names will have to be defined in the enclosing document, which is
automatically written if the path of a color file colorFileName is
set.
tikz() returns no values.
To compile the output of tikz a working installation of LaTeX
and PGF is needed. Current releases of the TikZ package are available
from https://www.ctan.org. The package may also be installed through
the MikTeX package manager on Windows or using the TeX Live package
manager, tlmgr, on Unix/Linux/OS X. The TeX Live package manager
will only be installed by default for TeX Live distributions dated 2008
and later. Both bleeding-edge and release versions of TikZ may be obtained
from the project website hosted at
https://sourceforge.net/projects/pgf/.
Multiple plots will be placed as separate environments in the output file.

tikzAnnotate is intended to allow the insertion of arbitrary TikZ
commands into the output stream of a graphic. For LaTeX commands that
reference specific locations in an R plot, coordinates must be specified in
"device units" which for tikz output are TeX points relative to the
lower left corner of the device canvas. Functions such as
grconvertX() and gridToDevice() can help make the
necessary conversions for base and grid graphics. The tikzNode and
tikzCoord functions automatically perform unit conversions acording
the the value of their units parameters.
tikzNode is a wrapper for tikzAnnotate that inserts TikZ
\\node or \\coordinates commands into the output. The
difference between a node and a coordinate is the presence of a
content section that can contain arbitrary LaTeX text. This is
useful for adding textual annotations at specific locations in a TikZ
graphic. The tikzCoord function is a wrapper for tikzNode
that simplifies the task of inserting named coordinates.
Additionally, the tikzAnnotateGrob, tikzNodeGrob and
tikzCoordGrob functions are supplied for creating grid objects
or "grob()s" that can be used in Grid graphics. High level
wrapper functions grid.tikzAnnotate, grid.tikzNode and
grid.tikzCoord are also supplied which creat and render a grob
in one step.
See the TikZ Device vignette for more information and examples and the TikZ manual for the definitive reference on what is possible with nodes.
