| 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 name of a decompression model:
one of "DSAT", "USN",
"Workman" or "ZH-L16A"
(partially matched).

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).
If model is "DSAT" or "USN", the model parameters
are extracted from the corresponding entries in the datasets
Halftimes and Mvalues. If model="Workman"
the model parameters are extracted from the
dataset Workman65. If model="ZH-L16A"
the model parameters are extracted from the
dataset BuehlmannL16A.
The vector of nitrogen tensions (in ata) in the most recently clicked stage.
