is_on_os_path: Is the path on the OS path?

In assertive.reflection: Assertions for Checking the State of R

Description

Is the specified path on the operating system search path?

Usage

assert_all_are_on_os_path(
  x,
  severity = getOption("assertive.severity", "stop")
)

assert_any_are_on_os_path(
  x,
  severity = getOption("assertive.severity", "stop")
)

is_on_os_path(x, .xname = get_name_in_parent(x))

Arguments

x	An path to check.
severity	How severe should the consequences of the assertion be? Either "stop", "warning", "message", or "none".
.xname	Not intended to be used directly.

Value

TRUE if the specified paths are on the OS search path.

Note

The OS search path is determined with Sys.getenv("path"). For files, the path of the containing folder is checked rather than the path of the file itself.

Examples

is_on_os_path(
  c(R.home("bin"), R.home("etc"), "a nonexistent path")
) # probably c(TRUE, FALSE, FALSE)
