Usage

dk_from_description(

  include_sysreqs = TRUE
)

Arguments

description_file: Path to DESCRIPTION file

Details

This function:

Extracts the R version from the DESCRIPTION's Depends field (if available)
Uses the appropriate rocker/r-ver base image
Extracts package dependencies from Depends, Imports, and Suggests fields
Adds system requirements for those packages
Sets up the package installation

The resulting dockerfile will install all the dependencies required by your package and then install the package itself from the source.
