| |
| <h3>Usage</h3> |
| |
| <pre> |
| not(x) |
| |
| ## S4 method for signature 'Column' |
| !x |
| |
| ## S4 method for signature 'Column' |
| not(x) |
| </pre> |
| |
| |
| <h3>Arguments</h3> |
| |
| <table summary="R argblock"> |
| <tr valign="top"><td><code>x</code></td> |
| <td> |
| <p>Column to compute on</p> |
| </td></tr> |
| </table> |
| |
| |
| <h3>Details</h3> |
| |
| <p><code>not</code> and <code>!</code> cannot be applied directly to numerical column. |
| To achieve R-like truthiness column has to be casted to <code>BooleanType</code>. |
| </p> |
