plot.tidem: Plot a tidal fit

Description

Plot a summary diagram for a tidal fit.

Usage

## S3 method for class 'tidem':
plot(x, 
     which=1,
     label.if=NULL, 
     log="",
     mgp=getOption("oceMgp"), 
     mar=c(mgp[1]+1,mgp[1]+1,mgp[2]+0.25,mgp[2]+1),
     ...)

Arguments

x

a tidem object, as created by tidem.

which

integer flag indicating plot type, 1 for stair-case spectral, 2 for spike spectral.

label.if

if NULL, the function will indicate some particular tidal constituents; if a value is provided, labels will be given for any constituent with amplitude exceeding the value provided.

log

if set to "x", the frequency axis will be logarithmic.

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").

...

optional arguments passed to plotting functions.

Details

Creates a plot for a "tidem" object. See tidem for examples.

tidem fits a "tidem" object, and summary.tidem summarizes such an object.
