R platforms
current_r_platform()
current_r_platform_data()
default_platforms()
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$new()
,
repo_status()
, etc.
These functions accept the following platform names:
"source"
for source packages,
"macos"
for macOS binaries that are appropriate for the R versions
pkgcache is working with. Packages for incompatible CPU architectures are
dropped (defaulting to the CPU of the current macOS machine and x86_64 on
non-macOS systems). The macOS Darwin version is selected based on the
CRAN macOS binaries. E.g. on R 3.5.0 macOS binaries
are built for macOS El Capitan.
"windows"
for Windows binaries for the default CRAN architecture.
This is currently Windows Vista for all supported R versions, but it
might change in the future. The actual binary packages in the
repository might support both 32 bit and 64 builds, or only one of
them. In practice 32-bit only packages are very rare. CRAN builds
before and including R 4.1 have both architectures, from R 4.2 they
are 64 bit only. "windows"
is an alias to i386+x86_64-w64-mingw32
currently.
A platform string like R.version$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.
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.
