plot.topo {oce} | R Documentation |
Plot contours of topographic data.
## S4 method for signature 'topo' plot(x, xlab="", ylab="", asp, clongitude, clatitude, span, expand=1.5, water.z, col.water, lty.water, lwd.water, land.z, col.land, lty.land, lwd.land, geographical=FALSE, location="topright", mgp=getOption("oceMgp"), mar=c(mgp[1]+1,mgp[1]+1,1,1), debug=getOption("oceDebug"), ...)

Aspect ratio for plot. The default is for |

numerical factor for the expansion of plot limits,
showing area outside the plot, e.g. if showing a ship track as a
coastline, and then an actual coastline to show the ocean boundary.

The plot aspect ratio is set based on the middle latitude in the plot. Be aware that the ETOPO2 data are on a 2-minute (roughly 2-mile) spacing, and coastlines created with such data can be quite inaccurate on scales of 100km or less.
The line properties, such as land.lwd
, may either be a single
item, or a vector; in the latter case, the length must match the
length of the corresponding properties, e.g. land.z
.
