Description

Mark a 24 hour seismic display

Usage

1
2
markseis24(pjj, pix = list(yr = 2009, jd = 1, hr = 0, mi = 0, sec = 0,
dur = 0), col = "red", LEGON = 3, BARON = TRUE, ARROWS = TRUE, lwd=1)

Arguments

pjj

Output information from plotseis24 (x,y, yr, jd)

pix

list: date list consisting of: yr, jd, hr, mi, sec, dur)

col

Color, specified as color index, character string or rgb

LEGON

plotting flag for legs: 0=no legs, 1=left leg, 2=right leg, 3=both legs(def ault)

BARON

logical:plotting flag for bar

ARROWS

logical: plot arrows FALSE=no arrows

lwd

numeric, graphical parameter, line width

Details

the LEGON parameter controls the small marks at the ends: Either left(1) right(2) both(3) or no legs(0) are plotted. window bars should wrap around the ends of the hour to the next hour below. The durations of the windows are supplied in seconds. If no duration is supplied, it is set to 0. If one duration is supplied it is copied to all other windows.

Value

Graphical Side effects
