assert_r_can_find_tools
Can R find tools?
Checks to see if R can see command line tools.
Usage
assert_r_can_find_tools(
tools,
severity = getOption("assertive.severity", "stop")
)assert_r_can_compile_code(severity = getOption("assertive.severity", "stop"))
assert_r_can_build_translations(
severity = getOption("assertive.severity", "stop")
)
assert_r_can_find_java(
java_type = c("same_as_r", "any", "64bit", "32bit"),
severity = getOption("assertive.severity", "stop")
)
r_can_find_tools(tools)
r_can_compile_code()
r_can_build_translations()
r_can_find_java(java_type = c("same_as_r", "any", "64bit", "32bit"))
Arguments
- tools
A character vector of tools to look for.
- severity
How severe should the consequences of the assertion be? Either
"stop","warning","message", or"none".- java_type
A string denoting the type of Java to look for (either 32 or 64 bit).
Value
The is_* functions return TRUE if the input is
within an interval. The assert_* functions return nothing but
throw an error if the corresponding is_* function returns
FALSE.
Note
r_can_compile_code is a convenience function looking for
gcc and make.
r_can_build_translations is a convenience function looking for
gettext and msgfmt.
