mapZones {oce} | R Documentation |
Plot zones (lines of constant longitude) on a existing map. DEPRECATED–will be removed by end Sept 2014
mapZones(longitude, polarCircle=0, lty='solid', lwd=0.5*par('lwd'), col='darkgray', ...)
longitude |
either a boolean indicating whether to draw a zonal grid, or a vector of longitudes at which to draw zones. |
polarCircle |
a number indicating the number of degrees of latitude extending from the poles, within which zones are not drawn. |
lty |
line type |
lwd |
line width |
col |
colour |
... |
optional arguments passed to |
Zones that will not fit in the plotting space are ignored.
This should use approx
to fill in multiple
segments within the line, so that e.g. great circle lines will be curved.
