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.
