Source: R/package.R
pkg_download.Rd

TODO: explain result

Usage

pkg_download(
  pkg,
  dest_dir = ".",
  dependencies = FALSE,
  platforms = NULL,
  r_versions = NULL
)

Arguments

pkg

Package names or package references. E.g.

  • ggplot2: package from CRAN, Bioconductor or a CRAN-like repository in general,

  • tidyverse/ggplot2: package from GitHub,

  • tidyverse/ggplot2@v3.4.0: package from GitHub tag or branch,

  • https://examples.com/.../ggplot2_3.3.6.tar.gz: package from URL,

  • .: package in the current working directory.

See "Package sources" for more details.

dest_dir

Destination directory for the packages. If it does not exist, then it will be created.

dependencies

What kinds of dependencies to install. Most commonly one of the following values:

  • NA: only required (hard) dependencies,

  • TRUE: required dependencies plus optional and development dependencies,

  • FALSE: do not install any dependencies. (You might end up with a non-working package, and/or the installation might fail.) See Package dependency types for other possible values and more information about package dependencies.

platforms

Types of binary or source packages to download. The default is the value of pkgdepends::default_platforms().

r_versions

R version(s) to download packages for. (This does not matter for source packages, but it does for binaries.) It defaults to the current R version.

Value

Data frame with information about the downloaded packages, invisibly. Columns: include_docs("pkgdepends", "docs/download-result.rds")
