check.signal: check.signal

In AnalysisPageServer: A framework for sharing interactive data and plots from R through the web

Description

Check if an expression results in a signal being delivered

Usage

check.signal(expr, signo, testname, no.signal = FALSE)

Arguments

expr	The expression to evaluate
signo	The signal number (consider using constants like SIGUSR1 from the tools package).
testname	Name for this test. Default is to build from signo argument.
no.signal	Logical, to invert the sense of the test. Default, FALSE, means to test that the signal was delivered. TRUE means to test that the signal was not delivered.

Details

Check if an expression results in a signal being delivered. The signal will be caught: you can safely deliver a signal such as SIGUSR1 that would normally cause the process to die.

Value

The value of the evaluated expression, invisibly, so you can do more testing if desired.
