Matrix of several seismograms
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)
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 |
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
