Operating system and environment checks

Source: R/os_checks.R
os.Rd

Determine the current operating system and R environment, and provide simple flags for common questions such as "are we on a Mac?", "is this 64-bit R?", or "are we running inside RStudio?". These are useful when writing code that must behave differently across platforms (for example, choosing a parallel back-end on Unix versus Windows).

Usage

get_os()

get_R_version()

get_R_version_age(units = c("years", "months", "weeks", "days"), rounding = 2)

get_latest_CRAN_version()

get_system_python()

is.os_mac()

is.os_win()

is.os_lnx()

is.os_unx()

is.os_x64()

is.os_arm()

is.R_x64()

is.R_revo()

is.RStudio()

is.http_available()

Arguments

units

character; the unit to report the R version age in, one of "years", "months", "weeks", or "days".

rounding

integer; the number of decimal places to round the age to.

Value

For the is.* checks, a single logical value. get_os() returns a character string ("win", "mac", "linux", or "unix"); get_R_version() and get_latest_CRAN_version() return version strings; and get_R_version_age() returns a numeric age.
