design-helpers: Test and get edibble objects

In edibble: Encapsulating Elements of Experimental Design

Test and get edibble objects

Description

The is functions tests if an object (or an object in its attribute) inherits particular class and returns TRUE if it does, otherwise FALSE.

• is_edibble_design checks if it inherits edbl_design.

• is_edibble_graph checks if it inherits edbl_graph.

• is_edibble_table checks if it inherits edbl_table

• is_edibble checks if the object inherits edbl. The search is quite simple, it checks if the object is edbl_design, failing that it looks to see if the attribute "design" of the object is edbl_design.

• is_named_design check if it inherits NamedDesign.

The get functions extracts the requested edibble component (table, graph, or design) from the object if possible.

• edbl_design tries to get edbl_design.

• edbl_table tries to get edbl_table with no design attribute.

• edbl_graph tries to get edbl_graph.
