'scuba' is a contributed package that performs theoretical calculations about scuba diving --- dive profiles, decompression models, gas toxicity and so on.
New features in version 1.2-2:
. Package vignette provides detailed explanations.
. Improved handling of data from dive computers.
. Gas switches (switching from one tank of breathing gas
to another during the dive) are now easy to specify.
. Relative tissue saturations can be computed easily
. Eleven new datasets: real dive profiles
. Dives with multiple tanks of breathing gas are now plotted
using a different colour for each gas.
whichtank whichtank<- Choice of breathing gas tank at each waypoint during the dive
dive For easier handling of data uploaded from dive computers, dive() now accepts elapsed time values in the formats "hh:mm:ss", and "mm:ss" where mm can exceed 60. plot.dive Dives with multiple tanks of breathing gas are now plotted using a different colour for each gas. The choice of colours is controlled by the argument 'col.gases'. haldane This function has a new argument 'relative'. If relative=TRUE, tissue saturations are computed as fractions of the surfacing M-value. ndl Improved numerical stability, in mixed-gas case. The return value of ndl now has an attribute which identifies the controlling tissue. showstates Improved plot labels.
