as.gps

the longitude in decimal degrees, positive east of
Greenwich, or a data frame with columns named <code>latitude</code> and
<code>longitude</code>, in which case these values are extracted from the data
frame and the second argument is ignored.

longitude

the latitude in decimal degrees, positive north of the
Equator.

latitude

name of file containing data (if applicable).

filename

Coerces a sequence of longitudes and latitudes into a GPS dataset.
This may be used when <code><a rd-options="=read.gps" href="/link/read.gps()?package=oce&version=1.4-0&to=%3Dread.gps" data-mini-rdoc="=read.gps::read.gps()">read.gps()</a></code> cannot read a file, or when the
data have been manipulated.

Supports the analysis of Oceanographic data, including 'ADCP'
measurements, measurements made with 'argo' floats, 'CTD' measurements,
sectional data, sea-level time series, coastline and topographic data, etc.
Provides specialized functions for calculating seawater properties such as
potential temperature in either the 'UNESCO' or 'TEOS-10' equation of state.
Produces graphical displays that conform to the conventions of the
Oceanographic literature. This package is discussed extensively in
Dan Kelley's book Oceanographic Analysis with R, published
in 2018 by 'Springer-Verlag' with ISBN 978-1-4939-8842-6.
