XSECwin: Cross sectional plot with earthquakes projected

Description

Cross section of earthquakes.

Usage

XSECwin(SW, iseclab = 1, xLAB = "A",
labs = c("DONE", "REFRESH", "PS"), width = 10, demo = FALSE)

Value

Graphical Side effects

Arguments

SW

list of swath data

iseclab

section number

xLAB

Label

labs

labels

width

width of swath

demo

logical, TRUE=not interactive

Author

Details

Called by XSECEQ; but this can be run independantly if plots are needed after interactive processing.
