windows/shell.exec: Open a File or URL using Windows File Associations

Description Usage Arguments Details Value Author(s) See Also Examples

Description

Opens the specified file or URL using the application specified in the Windows file associations.

Usage

1

Arguments

file

file or URL to be opened.

Details

The path in file should be a full path.

If the path in file is not a full path, it is interpreted relative to the current working directory, but in R versions 2.13.0 and earlier it was interpreted relative to the R home directory. To be interpreted as relative, the path also needs to use backslashes as separators (at least in Windows 10).

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.
