drawIsopycnals: Add Isopycnal Curves to TS Plot

Description

Adds isopycnal lines to an existing temperature-salinity plot. This is called by plotTS, and may be called by the user also, e.g. if an image plot is used to show TS data density.

Usage

drawIsopycnals(nlevels = 6, levels, rotate = TRUE, rho1000 = FALSE,
  digits = 2, eos = getOption("oceEOS", default = "gsw"), cex = 0.75
  * par("cex"), col = "darkgray", lwd = par("lwd"), lty = par("lty"))

Arguments

nlevels

suggested number of density levels (i.e. isopycnal curves); ignored if levels is supplied.

levels

optional density levels to draw.

rotate

boolean, set to TRUE to write all density labels horizontally.

rho1000

boolean, set to TRUE to write isopycnal labels as e.g. 1024 instead of 24.

digits

number of decimal digits to use in label (supplied to round).

eos

equation of state to be used, either "unesco" or "gsw".

cex

size for labels.

col

color for lines and labels.

lwd

line width for isopcynal curves

lty

line type for isopcynal curves

Value

None.
