check.signal {AnalysisPageServer} | R Documentation

## check.signal

### 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.
