TideTables 0.0.3

Last updated on Dec 16, 2020 1 min read

Hi,

if you are interested in analyzing and synthesizing tide tables, you should check out the new version of TideTables. Version 0.0.3 is now on CRAN https://cran.r-project.org/web/packages/TideTables/index.html

Main changes are:

Introducing two new functions: BuildTT and SynTT.
TideTable is again (up to ~50 times) faster, uses less RAM and has a new parameter strict_hwi.
Minor changes in helper functions, which do not affect the output.
Using a new set of angular velocities.
The output format of date/time is now the same as the expected input format.
Two new internal functions FindOmega and ComputeAfunc introduced. For internal use only!

The two new functions allow you to build a model of class tidetable given a certain time frame and then later use this model to synthesize a tide table by using SynTT. You will experience a major speed up of the TideTable function, if you have used the package version 0.0.2. We also updated the set of angular velocities due to the work of Andreas Boesch and Sylvin Mueller-Navarra, which you can find here: https://os.copernicus.org/articles/15/1363/2019/

The package is on also available on github: https://github.com/moritzmn/TideTables

Best, Moritz
