element_latex: ggplot2 Theme Element Supporting Latex Syntax

Description

This theme element is an alternative to ggplot2::element_text() for producing labels from LaTeX fragments.

Both hjust and vjust can be character values: one of "left", "bbleft", "centre", "center", "right", "bbright" for horizontal justification; and one of "bottom", "baseline", "centre", "center", or "top" for vertical justification.

Usage

element_latex(family=NULL,
              fontface=NULL,
              colour=NULL,
              size=NULL,
              hjust=NULL, vjust=NULL,
              angle=NULL,
              lineheight=NULL,
              color=NULL,
              margin=NULL,
              width=NULL,
              packages=NULL,
              engine=getOption("xdvir.engine"),
              rotate_margins=FALSE,
              inherit.blank=FALSE)

Value

An element_latex object that can be used in place of element_text in ggplot2 theme specifications

Arguments

family: The default font family.
fontface: The default font face.
colour, color: The default text colour.
size: The deafult font size.
hjust: Horizontal justification. Typically in \([0, 1]\), but see Details.)
vjust: Vertical justification. Typically in \([0, 1]\), but see Details.)
angle: Angle (in \([0, 360]\))
lineheight: The deafult lineheight.
margin: The margin around the text.
width: Either NA or a numeric value or a unit specifying the width for typesetting. NA means the natural width of the label.
packages: The LaTeX packages to be used. May be the name of a LaTeX package (character) or a "LaTeXpackage" object.
engine: The TeX engine that should be used to render the LaTeX. May be the name of a TeX engine (character) or a "TeXengine" object.
rotate_margins: Whether margins should follow the orientation of the text.
inherit.blank: Should this element inherit the existence of an element_blank among its parents? If TRUE the existence of a blank element among its parents will cause this element to be blank as well. If FALSE any blank parent element will be ignored when calculating final element state.
