Plot a tidal fit

Description

Plot a summary diagram for a tidal fit.

Usage

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

Arguments

x a tidem object, as created by tidem.
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.
plot.type character string indicating the plot type. The "staircase" style shows a cumulative representation, in which rising portions indicate the energy in the tidal constituents. The "spike" style is in the more conventional spectral form. If a large number of constituents is being used, the staircase style can be simpler to read at a glance.
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.
