tinytex VS shinyjs

Some of the others have mentioned other installs, but they can pull down a lot of packages which might not be ideal if it's not your PC (even the TexLive install is quite chonky.) I'd personally recommend: TinyTex.

See https://yihui.org/tinytex

that will install a lightweight latex distribution ready to render your rmarkdown documents. just restart rstudio and give a try after this process (for more stuff, see https://yihui.org/tinytex/ )

Have you tried the things mentioned at the link? https://github.com/yihui/tinytex/issues/24

There is the tinyTeX distribution which was designed for use with R, but can be used on its own as well. It's a subsetted version of TeX live and available from https://yihui.org/tinytex/

If you'd like to install only a small subset of packages, there are projects like TinyTeX.

Tinytex is a relative new Latex distribution by Yihui Xie from the R community. The distribution is tiny, less than 100mb, which is a great alternative to TexLive and MikTex for basic users.

Also, if you want to show/hide a box depending on a parameter, you can observe whether the parameter is present or not, then simply show/hide the box with the shinyjs package.

Have a look at shinyjs. https://deanattali.com/shinyjs/ https://github.com/daattali/shinyjs#overview-main There you can specify which blocks of ui are hidden from the start, you can enable and disable inputs, show and hide, and much more.

Shiny is an R package that makes it easy to build interactive web apps straight from R. You can host standalone apps on a webpage or embed them in R Markdown documents or build dashboards. You can also extend your Shiny apps with CSS themes, htmlwidgets, and JavaScript actions.
