Test and get edibble objects

Source: R/edibble.R
design-helpers.Rd

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.
