R platforms

Source: R/platform.R
default_platforms.Rd

default_platfoms() returns the default platforms for the current R session. These typically consist of the detected platform of the current R session, and "source", for source packages.

Usage

current_r_platform()

default_platforms()

Value

current_r_platform() returns a string, the name of the current platform.

default_platforms() returns a character vector of platform names.

Details

current_r_platform() detects the platform of the current R version.

By default pkgdepends works with source packages and binary packages for the current platform. You can change this, see 'Configuration'.

The following platform names can be configured and returned by current_r_platform() and default_platforms():

  • "source" for source packages,

  • A platform string like R.version$platform, but on Linux the name and version of the distribution are also included. Examples:

    • x86_64-apple-darwin17.0: macOS High Sierra.

    • aarch64-apple-darwin20: macOS Big Sur on arm64.

    • x86_64-w64-mingw32: 64 bit Windows.

    • i386-w64-mingw32: 32 bit Windows.

    • i386+x86_64-w64-mingw32: 64 bit + 32 bit Windows.

    • i386-pc-solaris2.10: 32 bit Solaris. (Some broken 64 Solaris builds might have the same platform string, unfortunately.)

    • x86_64-pc-linux-gnu-debian-10: Debian Linux 10 on x86_64.

    • x86_64-pc-linux-musl-alpine-3.14.1: Alpine Linux.

    • x86_64-pc-linux-gnu-unknown: Unknown Linux Distribution on x86_64.

    • s390x-ibm-linux-gnu-ubuntu-20.04: Ubuntu Linux 20.04 on S390x.

    • amd64-portbld-freebsd12.1: FreeBSD 12.1 on x86_64.

In addition, the following platform names can be used to configure pkgdepends:

  • "macos" for macOS binaries that are appropriate for the R versions pkgdepends is working with (defaulting to the version of the current session), as defined by CRAN binaries. E.g. on R 3.5.0 macOS binaries are built for macOS El Capitan.

  • "windows" for Windows binaries for the default CRAN architecture. This is currently Windows Vista for all supported R versions, but it might change in the future. The actual binary packages in the repository might support both 32 bit and 64 builds, or only one of them. In practice 32-bit only packages are very rare. CRAN builds before and including R 4.1 have both architectures, from R 4.2 they are 64 bit only. "windows" is an alias to i386+x86_64-w64-mingw32 currently.
