plotProfile: Plot a CTD profile of various quantities

Description

Plot a CTD profile, in any of several common formats.

Usage

plotProfile(x,
             xtype="salinity+temperature", 
             ytype=c("pressure", "z", "sigmaTheta"),
             col.salinity="darkgreen",
             col.temperature="red",
             col.rho="blue",
             col.N2="brown",
             col.dpdt="darkgreen",
             col.time="darkgreen",
             grid=TRUE,
             col.grid="lightgray",
             lty.grid="dotted",
             Slim, Tlim, densitylim, N2lim, dpdtlim, timelim, ylim,
             lwd=par("lwd"),
             xaxs="r", yaxs="r",
             cex=1, pch=1,
             useSmoothScatter=FALSE,
	     keepNA=FALSE,
             type='l',
             mgp=getOption("oceMgp"),
             mar=c(1 + if (length(grep('\\+', xtype))) mgp[1] else 0, mgp[1]+1, mgp[1] + 2, 1),
             debug=getOption("oceDebug"),
             ...)

Arguments

x

A cdt object, e.g. as read by read.ctd.

xtype

Item(s) plotted on the x axis, from the list below. [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

ytype

variable to use on y axis.

col.salinity

Color for salinity profile.

col.temperature

Color for temperature.

col.rho

Color for density.

col.N2

Color for square of buoyancy frequency.

col.dpdt

Color for dP/dt.

col.time

Color for delta-time.

grid

logical, set to TRUE to get a grid.

col.grid

colour for grid.

lty.grid

line type for grid.

Slim

Optional limit for S axis

Tlim

Optional limit for T axis

densitylim

Optional limit for density axis

N2lim

Optional limit for N2 axis

dpdtlim

Optional limit for dp/dt axis

timelim

Optional limit for delta-time axis

ylim

Optional limit for y axis

lwd

lwd value for data line

xaxs

value of par xaxs to use

yaxs

value of par yaxs to use

cex

size to be used for plot symbols (see par)

pch

code for plotting symbol (see par).

useSmoothScatter

boolean, set to TRUE to use smoothScatter instead of plot to draw the plot.

keepNA

FALSE

type

type of plot to draw, using the same scheme as plot.

mgp

3-element numerical vector to use for par(mgp), and also for par(mar), computed from this. The default is tighter than the R default, in order to use more space for the data and less for the axes.

mar

value to be used with par("mar").

debug

a flag that turns on debugging, if it exceeds 0.

...

Optional arguments passed to other functions. A common example is to set df, for use in swN2 calculations.

Value

• None.
