In moritzmn/TideTables: Tide Analysis and Prediction of Predominantly Semi-Diurnal Tides

Builds a TideTable model

Description

Builds a TideTable model of class "tidetable".

Usage

BuildTT(
  dataInput,
  otz = 1,
  asdate,
  astime,
  aedate,
  aetime,
  hwi = "99:99",
  sharp_hwi = TRUE
)

Arguments

dataInput	the data frame with observation date, observation time and height.
otz	time zone of the observations. Default is 1 (UTC + 1)
asdate	The start date.Format: "yyyy/mm/dd"
astime	The start time. Format: "hh:mm:ss"
aedate	The end date. Format: "yyyy/mm/dd"
aetime	The end time. Format: "hh:mm:ss"
hwi	The high water interval. Format: "hh::mm"
sharp_hwi	should the hwi computation be sharp? Default is TRUE

Value

Returns a object of class "tidetable" which contains following elements:

fitting.coeff	Coefficients for the eight fitted linear models used in the synthesis
diff.analyse	Time in days spanning the analysis
omega_t	Return value of FindOmega()
tm24	Internal constant
tplus	Internal constant
tmhwi	Mean high water interval
