        scuba 1.2-2

'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.

New functions:

        whichtank
        whichtank<-
                        Choice of breathing gas tank
                        at each waypoint during the dive

Improvements:

        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.
