texPreview

Efficiently iterate, refine and share snippets of LaTeX in R with ease.

texPreview compiles LaTeX directly into images from the R console to view in the RStudio viewer pane, Shiny apps and RMarkdown documents.

Functionality

• Supports: character, knitr, kableExtra, xtable, texreg, equatiomatic classes

• Extendable: S3 methods can be written for the main call, texPreview::tex_preview, to use with new classes for rendering and printing.

• Rstudio Addin: Users can highlight text in the editor and invoke preview automatically.

• RMarkdown document compatible with all document outputs

• Shiny compatible via shiny::renderImage or as part of htmlwidgets like slickR::slickR.

• Pan and Zoom functionality: When the output is set to ‘svg’ the default output to the viewer is svgPanZoom::svgPanZoom, which allows for panning and zooming on the image in the viewer. If the package is not installed a static image will be loaded.

• System Requirements:

  • Must have pdflatex in PATH, Windows users can install by running installr::install.MikTeX
  • TeX libraries that are used: standalone, xcolor, booktabs, multirow, array, helvet, amsmath, rotating, listings, graphicx, setspace, caption

    • Using tinytex you can run

      install.packages('tinytex')
      tinytex::tlmgr_install(c('standalone', 'xcolor', 'booktabs', 'multirow', 'amsmath',
      'listings', 'setspace', 'caption', 'graphics', 'tools', 'psnfss', 'varwidth',
      'colortbl', 'epstopdf-pkg', 'pgf','makeindex'))

    • To Check if the system is in compliance with these libraries run texPreview::check_requirements().

  • Ghostscript: If you are installing TeX with tinytex make sure to install ghostscript onto your system.
