R platforms
Description
R platforms
Usage
current_r_platform()
current_r_platform_data()
default_platforms()
Details
current_r_platform()
detects the platform of the current R version.
current_r_platform_data()
is similar, but returns the raw data instead
of a character scalar.
By default pkgcache works with source packages and binary packages for
the current platform. You can change this, by providing different
platform names as arguments to
cranlike_metadata_cache$new()
,
repo_status()
, etc.
These functions accept the following platform names:
-
"source"
for source packages, -
"macos"
for macOS binaries that are appropriate for the R versions pkgcache is working with. Packages for incompatible CPU architectures are dropped (defaulting to the CPU of the current macOS machine and x86_64 on non-macOS systems). The macOS Darwin version is selected based on the CRAN macOS binaries. E.g. on R 3.5.0 macOS binaries are built for macOS El Capitan. -
"windows"
for Windows binaries for the default CRAN architecture. This is currently Windows Vista for all supported R versions, but it might change in the future. The actual binary packages in the repository might support both 32 bit and 64 builds, or only one of them. In practice 32-bit only packages are very rare. CRAN builds before and including R 4.1 have both architectures, from R 4.2 they are 64 bit only."windows"
is an alias toi386+x86_64-w64-mingw32
currently. A platform string like
R.version$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.

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.
Value
current_r_platform()
returns a character scalar.
current_r_platform_data()
returns a data frame with character
scalar columns:
-
cpu
, -
vendor
, -
os
, -
distribution
(only on Linux), -
release
(only on Linux), -
platform
: the concatenation of the other columns, separated by a dash.
default_platforms()
returns a character vector of the
default platforms.
