concatenate.NULL

Concatenates null. Returns empty string.

internal

The 'spork' syntax describes
label formatting concisely, supporting
mixed nesting of subscripts and superscripts
to arbitrary depth. It intends to be easy
to read and write in plain text, and easy
to convert to equivalent presentations
in 'plotmath', 'latex', and 'html'.  Greek symbols
and a multiplication symbol are explicitly
supported. See ?as_spork and ?as_previews.
