Description Usage Arguments Details See Also Examples
A basic user settings facility, like options
and
lattice.options
.
1 2 |
name |
character giving the name of a setting. |

new options can be defined, or existing ones modified, using one or more arguments of the form 'name = value' or by passing a list of such tagged values. Existing values can be retrieved by supplying the names (as character strings) of the components as unnamed arguments. |
These functions are direct copies of the lattice equivalents:
see lattice.options
.
The available options can be seen with str(playwith.options())
.
Many of these simply provide defaults for corresponding arguments
to the playwith
function.
