get_dep_df {crandep}

Multiple types of dependencies

Description

get_dep returns a data frame of multiple types of dependencies of a package

Usage

get_dep_df(name, type, scrape = TRUE)

get_dep_all(name, type, scrape = TRUE)

get_dep(name, type, scrape = TRUE)

Arguments

name

String, name of the package

type

A character vector that contains one or more of the following dependency words: "Depends", "Imports", "LinkingTo", "Suggests", "Enhances", "Reverse depends", "Reverse imports", "Reverse linking to", "Reverse suggests", "Reverse enhances", up to letter case and space replaced by underscore. Alternatively, if 'type = "all"', all ten dependencies will be obtained.

scrape

Boolean. If 'TRUE' (default), the page of the package will be scraped. If 'FALSE', tools::CRAN_package_db() will be used. Whether the argument equals 'TRUE' or 'FALSE' should not affect the output, but only the time taken. Usually, the former is faster than the latter for a single package.

Value

A data frame of dependencies

See Also

get_dep_all_packages for the dependencies of all CRAN packages, and get_graph_all_packages for obtaining directly a network of dependencies as an igraph object

Examples

get_dep("dplyr", c("Imports", "Depends"))
get_dep("MASS", c("Suggests", "Depends", "Imports"), TRUE) # FALSE will give same result
