matrixShiftLongitude

Sometimes datasets are provided in matrix form, with first
index corresponding to longitudes ranging from 0 to 360.
<code>matrixShiftLongitude</code> cuts such matrices at
longitude=180, and swaps the pieces so that the dateline
is at the left of the matrix, not in the middle.

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 by
Kelley (2018) "Oceanographic Analysis with R" <doi:10.1007/978-1-4939-8844-0>.
