Find current installations

Despite the description minimal requirements find which versions are required due to dependencies. Reports the minimal version for each package that would be installed now.

Usage

package_dependencies(packages = ".", which = "strong")

Arguments

packages

Path to a folder with a DESCRIPTION file or package's names from a repository. If NULL will pick all packages and their dependencies available.

which

a character vector listing the types of dependencies, a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances"). Character string "all" is shorthand for that vector, character string "most" for the same vector without "Enhances", character string "strong" (default) for the first three elements of that vector.

Value

A data.frame with the Package, Type, Name, Op and Version required. If only one package requires it it also show the name of the package. NA if not able to collect the data from repositories.

Note

It keeps the base packages too even if just knowing the R version required would be enough.

Examples

pd <- package_dependencies("ggeasy")
head(pd)
#>        Package    Type  Name Op Version
#> 1           R6 Depends     R >=   4.1.0
#> 2 RColorBrewer Depends     R >=   4.1.0
#> 3           S7 Depends     R >=   4.1.0

#> 5          cli Depends     R >=   4.1.0
