Depending on the function prefix: If the check is successful, the functions
assertOS/assert_os return
x invisibly, whereas
checkOS/check_os and
testOS/test_os return
TRUE.
If the check is not successful,
assertOS/assert_os
throws an error message,
testOS/test_os
returns FALSE,
and checkOS/check_os
return a string with the error message.
The function expect_os always returns an
[character(1)]
Check the operating system to be in a set with possible elements “windows”,
“mac”, “linux” and “solaris”.
