matsquiggle {RSEIS}R Documentation

Matrix Seismic Record

Description

Plot a matrix of time series as a var-squiggle display (filled in half traces)

Usage

matsquiggle(XMAT, dt1, dist = NULL, thick = 1, FLIP = FALSE, filcol='blue', tracecol="black", add=FALSE, PLOT=TRUE)

Arguments

XMAT matrix of traces
dt1 sample interval, s
dist distance for each trace in the matrix
thick thickness for each trace to be plotted
FLIP logical, FALSE (default) plot horizontal, TRUE=plot vertical
filcol color for shading
tracecol color for trace
add add traces to existing plot
PLOT whether to create a new plotting region

Details

see varsquiggle for more details

Value

side effects.

###  plot normal way:
### PICK.GEN(GH, sel=sel, WIN=c(5,10), SHOWONLY=TRUE)

###  plot with varsquiggle
### varsquiggle(GH, sel=sel, WIN=c(5,10))
