get_package_deps: Create a list of R Package Dependencies

Description

Given a path to a directory this function will scan all .R and .Rmd files for any used R Packages along with their CRAN versions or GitHub references.

Usage

get_package_deps(app_dir = ".", verbose = TRUE)

Value

a list of package dependencies

Arguments

app_dir

path to a directory containing R scripts or R Markdown files. Defaults to current working directory if left blank.

verbose

boolean (default: TRUE) - Provide feedback about detected invalid R packages.

Details

Currently, detections are made via automagic::parse_packages() which supports the following calls within the code: library(), require(), and prefixed :: calls to functions.

Once an initial vector of package detections is built, it is further processed by validating that each detection is indeed a valid CRAN or public GitHub package and can be installed.
