|
An object of class "gas"
represents a breathing gas.
Such objects are required for various calculations in the
scuba
library.
The dataset air
represents compressed air (21% oxygen,
79% nitrogen) as a breathing gas. It is equivalent to
nitrox(0.21)
.
The function is.air
expects its argument g
to be a gas object. It returns TRUE
if
g
is equivalent to air, and FALSE
otherwise.
