Compare DESCRIPTION files dependencies between specific CRAN packages versions

using the remote github CRAN mirror to compare DESCRIPTION files dependencies between specific packages versions.

pac_compare_versions(
  pac,
  old = NULL,
  new = NULL,
  fields = c("Imports", "Depends", "LinkingTo"),
  lib.loc = .libPaths(),
  repos = "https://cran.rstudio.com/"
)

Arguments

pac

character a package name.

old

character an old version of package, default local version. Default: NULL

new

character a new version of package, default newest version. Default: NULL

fields

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. Default: c("Depends", "Imports", "LinkingTo")

lib.loc

character vector of search paths with local packages. Default: .libPaths()

repos

character vector repositories URLs to use. Used only for the validation. Default https://cran.rstudio.com/

Value

data.frame with 4 columns.

Package

character package names.

Version.OLD

character versions of dependencies required by an old package version.

Version.NEW

character versions of dependencies required by a new package version.

version_status

numeric -1/0/1 which comes from utils::compareVersion function. 0 means that both versions have the same requirement. -1 means that the new version remove this requirement. 1 means that the new version added a new requirement.

Examples

if (FALSE) { # \dontrun{
pacs::pac_compare_versions("memoise", "0.2.1", "2.0.0")
pacs::pac_compare_versions("memoise", "0.2.1")
# local version to newest one
pacs::pac_compare_versions("memoise")
} # }
