Var-Squiggle Plot

Description

Plot A seismic section using Var-Squiggle, like an exploration seismic record.

Usage

varsquiggle(GH, sel = c(1, 2), WIN = c(0, 1), dist=NULL, thick=1 ,
FLIP=FALSE, filcol='blue', tracecol='blue')

Arguments

GH Seismic List
sel selection of seismic traces
WIN time window
dist distance from the source
thick thickness of plotting region per trace
FLIP logical, whether to plot vertical or horizontal, default FALSE, TRUE = vertical
filcol color for shading
tracecol color for trace

Details

Traces are plotted and scaled each with its own window. The distance vector provides the location on the seismic record.

Value

Graphical Side effects

Examples

data(GH)
m = match( GH$STNS,    GH$stafile$name)
LATS = GH$stafile$lat[m]
LONS = GH$stafile$lon[m]
dees = distaz( GH$pickfile$LOC$lat, GH$pickfile$LOC$lon, LATS, LONS)

sel = which(GH$COMPS=="V")
sel = sel[order(dees$dist[sel])]

###  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))
