Depending on the function prefix:
If the check is successful, the functions
assertDirectoryExists
/assert_directory_exists
return
x
invisibly, whereas
checkDirectoryExists
/check_directory_exists
and
testDirectoryExists
/test_directory_exists
return
TRUE
.
If the check is not successful,
assertDirectoryExists
/assert_directory_exists
throws an error message,
testDirectoryExists
/test_directory_exists
returns FALSE
,
and checkDirectoryExists
/check_directory_exists
return a string with the error message.
The function expect_directory_exists
always returns an
expectation
.
The functions without the suffix “exists” are deprecated and will be removed from the package in a future version due to name clashes.

checkAccess()
