Coerce Data Into an ladp object

This function assembles vectors of pressure and velocity, possibly also with shears, salinity, temperature, etc.

Usage

as.ladp(
  longitude,
  latitude,
  station,
  time,
  pressure,
  u,
  v,
  uz,
  vz,
  salinity,
  temperature,
  ...
)

longitude: longitude in degrees east, or an oce object that contains the data otherwise given by longitude and the other arguments.
latitude: latitude in degrees east (use negative in southern hemisphere).
station: number or string indicating station ID.
time: time at the start of the profile, constructed by e.g. as.POSIXct().
pressure: pressure in decibars, through the water column.
u: eastward velocity (m/s).
v: northward velocity (m/s).
uz: vertical derivative of eastward velocity (1/s).
vz: vertical derivative of northward velocity (1/s).
salinity: salinity through the water column, in practical salinity units.
temperature: temperature through the water column.
...: optional additional data columns.
