The tidedata dataset contains Tide-constituent
information that is use by tidem to fit tidal models.
tidedata is a list containing
namefreqkmprikmpr0 if there is nonedfd1d2d3d4d5d6seminsatishallownshallowdoodsonampdoodsonspeciessatdeldoodphcorrampratilatfaciconstshallowiconstcoefiname
Apart from the use of d1 through d6, the naming and
content follows T_TIDE. All of this is based on Foreman
(1977), to which the reader is referred for details.
To get a list of all the available tidal constituents, do
cat("all constituents:",tidedata$const$name)
and to get a list of the so-called standard coefficients, do
cat("standard constituents:",tidedata$const$name[tidedata$const$ikmpr])

The data come from the tide3.dat file of the
T_TIDE package (Pawlowicz et al., 2002), and derive from
Appendices provided by Foreman (1977). The data are scanned using
‘tests/tide.R’ in this package, which also performs some tests using
T_TIDE values as a reference.
