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.
