assert_all_are_executable_files

From assertive.files v0.0-1 by Richard Cotton

Is the file accessible?

Checks to see if the input files can be executed/read/written to.

Usage

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

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

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

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

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

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

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

is_ex_file(x)

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

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

Arguments

x: Input 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

is_executable_file wraps file.access, showing the names of the inputs in the answer. assert_is_executable_file returns nothing but throws an error if is_executable_file returns FALSE.

Examples

files <- dir()
is_readable_file(files)
is_writable_file(files)
is_executable_file(files)
