Check System Command Result for Exit Code

Description

Evaluates the result from R's system() function and checks for a non-zero exit status. If the system command failed (i.e., returned a non-zero exit status), the function throws an error. If the result contains the command's output, it is returned.

Usage

checkSystemResult(result)

Arguments

result

The result of a system() function execution. This can be: A character vector containing the command's output. A numeric value representing the exit status code. An object with a status attribute.

Value

• If result is a character vector (command output) and has no status attribute, returns the output.

• If result is numeric (exit status code), returns the status code.

• If the command failed (non-zero exit status), the function stops with an error message.
