showstates {scuba} | R Documentation |
Plots a dive profile and interactively displays the diver's nitrogen saturation state at any intermediate stage indicated by the mouse.
showstates(d, model="DSAT")
d |
The dive. An object of class "dive" .
|
model |
The decompression model. Either an object of class "hm"
or a character string identifying a model.
|
An object of class "dive"
represents a scuba dive.
It is created by the command dive
.
This function plots the dive using plot.dive
then waits for the user to click on the plot. This click selects
a time during the dive. The algorithm computes the nitrogen tensions
in the tissues at the indicated time, using haldane
,
and plots them as a bar graph. The cumulative oxygen toxicity is also
computed using oxtox
.
Note that the bar graph shows the relative nitrogen tensions in each compartment, that is, the tissue nitrogen tension divided by the "surfacing M-value" (tissue maximum nitrogen tension for a no-decompression dive at sea level).
The argument model
determines the decompression model.
It should be either an object of class "hm"
(created by
hm
) or a character string matching one of the
options in pickmodel
.
The vector of nitrogen tensions (in ata) in the most recently clicked stage.
