PLOT.MATN {RSEIS}R Documentation

plot a matrix of several seismograms

Description

Matrix of several seismograms

Usage

PLOT.MATN(ascd, tim=1, dt=1,  WIN=c(0,1), labs="", notes=notes, sfact=1,ampboost=0,  shift=NULL, LOG="", COL='red', add=1, AXES=1, units=NULL, VS=FALSE)

Arguments

ascd N by K matrix of seismograms where
tim time values fo x-axis
dt sample interval, seconds
WIN vector, time window for zoom
labs vector of labels for each panel
notes vector of notes for each panel
sfact scaling factor, 1=window, 2=trace
ampboost increase each amplitude by this multiplier
shift vector, shift each trace by these time
LOG log x-axis
COL vector of colors or indexes to colors
add logical, TRUE=add to existing plot
AXES numeric, 0,1,2,3,4; default=1
units label for units of Y-axis
VS var-squiggle display

Details

Plots a matrix of seismograms that each have the same starting time. For the AXES argument, 0 = no axes, AXES=1 plot scale for largest amplitude band and a multiplier for all others, AXES=2 left side, AXES=3 right side, AXES=4 alternate sides

Value

Graphical side effects and,

n n
windiv matrix of n rows, with columns=(window Y min, window Y max, user Y min, user Y max)

dt = 0.001

 t = seq(0, 6, by=0.001)

thefreqs = seq(from=10, to=100, by=10)
theamps =  runif(length(thefreqs))

#   
 x = NULL

for(i in 1:length(thefreqs))
{
x = cbind(x, theamps[i]*sin(2*pi*thefreqs[i]*t))
