knitr (version 1.34)

opts_knit: Options for the knitr package

Description

Options including whether to use a progress bar when knitting a document, and the base directory of images, etc.

Usage

opts_knit

Format

An object of class list of length 6.

Details

Besides the standard usage (opts_knit$set()), we can also set package options prior to loading knitr or calling knit() using options() in base R. A global option knitr.package.foo in options() will be set as an option foo in opts_knit, i.e. global options in base R with the prefix knitr.package. correspond to options in opts_knit. This can be useful to set package options in ~/.Rprofile without loading knitr.

See str(knitr::opts_knit$get()) for a list of default package options.
