Details

These functions are applied in post processing steps. The diff* methods do not do any of the formatting. Instead, the formatting is done only if the user requests to show the object. Internally, show first converts the object to a character vector using as.character, which applies every formatting function defined here except for container. Then show applies container before forwarding the result to the screen or pager.
