# Licences (CRAN)

Part of: [vcdExtra](/cran/vcdExtra.md)

## Licence

[Method](/about/licenses.md)

`GPL (>= 2)`, Copyleft

Licences in this family ask that works based on the licensed code carry the same licence when they are distributed, and the GPL asks for their source code as well.

| Licence | SPDX | OSI | FSF | Restricts use |
| --- | --- | --- | --- | --- |
| GPL-2 | GPL-2.0-only | approved | free | No |
| GPL-3 | GPL-3.0-only | approved | free | No |

### Families

- Permissive: Licences in this family ask little more than that the copyright notice and the licence text stay with copies.
- Copyleft: Licences in this family ask that works based on the licensed code carry the same licence when they are distributed, and the GPL asks for their source code as well.
- Terms in a file: The terms are only in the package's own licence file.

The mark: offers no permissive licence, in a family that raises the flag.
