timeplot {ssEDA}R Documentation

Plots Event Frequencies by Time

Description

Plots a histogram of the number of selected events by time interval, either months or years.

Usage

timeplot(events, yearly=TRUE, smoothline=FALSE, ymax=NA)

Arguments

events defines the events to be plotted. It is an object of class "subset", generally created by subsetcircle, subsetpolygon, subsetrect or subsetsphere.
yearly boolean. Should each bar represent annual TRUE or monthly FALSE counts. Default is TRUE.
smoothline boolean. Plot a smoothed line over the counts. Default is FALSE. The smoothing is done using the function supsmu which is contained in the package modreg.
ymax numeric, default is NA. Sets the upper limit of the y axis for the bar plot.

Examples

#    This example requires the NZ catalogue

require(ssNZ)

b <- subsetrect(NZ, minday=julian(1,1,1961), minmag=4,
                 minlat=-50, maxlat=-33.5, minlong=165, maxlong=180)
timeplot(b)
title(main=expression(paste("Events in NZ With ", M[L] >= 4)))
