R: plot a matrix of several seismograms

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` | numeric, to existing plot. add = 1,2,3 if add=1 plot and add traces, add =2 plot, but no traces, add = 3 no plot, but add traces. DEFAULT=1
`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)

### Examples

    dt  <-  0.001

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

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

    #   sample rate is 1000 Hz, 0.001 seconds 601 samples
     x  <-  NULL

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

    }

    PLOT.MATN(x,  dt = dt)
