sanitize_latex: Escape Characters for Printing in LaTeX Output

Description

sanitize_latex translates particular items in character strings to LaTeX format, e.g., makes a^2 = a\$^2\$ for superscript within variable labels. LaTeX names of greek letters (e.g., "alpha") will have backslashes added if greek==TRUE. Math mode is inserted as needed. sanitize_latex assumes that input text always has matches, e.g. [) [] (] (), and that surrounding by \$\$ is OK.

Usage

sanitize_latex(
  object,
  inn = NULL,
  out = NULL,
  pb = FALSE,
  greek = FALSE,
  na = "",
  ...
)

Value

Vector of chracter strings.

Arguments

object: character vector of strings to translate. Any NAs are set to blank strings before conversion.
inn: character vector. Additional strings to translate.
out: character vector the same length as inn. This gives the translated value of the corresonding element in inn
pb: logical(1) If pb=TRUE, sanitize_latex also translates [()] to math mode using \left, \right.
greek: logical(1). set to TRUE to have sanitize_latex put names for greek letters in math mode and add backslashes.
na: character(1) Single character string to translate NA values to.
...: Additional arguments for other methods. Currently ignored.
