Questions tagged [htmltools]

htmltools is an R package that contains tools for generating HTML output directly from R.

htmltools provides R users with a means to generate HTML output such as tags and styles directly from R. It provides additional development tools such as dependency identification and tag attribute management. htmltools provides much of the underlying HTML functionality for other common packages like Shiny and rmarkdown.

This tag should be used in questions that directly reference the htmltools package and could also be useful for questions related to other packages (like Shiny and rmarkdown) when the post involves functionality imported into that package from htmltools.
