##### Usage
shell.exec(file)
##### Arguments
file
file or URL to be opened.
##### Details

The path in file is interpreted relative to the current working directory. R versions 2.13.0 and earlier interpreted file relative to the R home directory, so a complete path was usually needed. Encoded file:// URLs should be in the Windows standard form, e.g. "file:///c:/path/to/file.txt".

##### Value

No value, but informative error messages will be given if the operation fails.
