An object of class vp.
Additional arguments affecting the summary produced.
An object of class vp.
For is.vp: TRUE if its argument is of class vp.
For dim.vp: dimensions of the profile data.
An object of class vp contains a vertical profile. A vertical profile
contains a collection of quantities, with each quantity having values at
different altitude layers above the earth's surface, typically equally
spaced altitudinal layers.
Data contained in this class object should be accessed with the
get_quantity function. Information stored under attributes
(see below) can be accessed directly.
