Plot a Schmidt diagram

Description

Plot a Schmidt diagram

Usage

schmidt.plot(x, ..., mode=1, radius = 1, ntick=4, nlabel=4, 
	    flag.pole=TRUE, flag.plan=TRUE, flag.line=FALSE, flag.back=FALSE,
	    opt.text=0, nclass=36, col="black", col0="grey",
	    title = NA, add = FALSE, reset = TRUE, verbose=FALSE)

Arguments

x

This argument defines the elements to be represetned. It may be:

  • db-class which contains the Dip-Dir and the Dip angles for the samples to be displayed

  • A matrix (with two columns) of elements to be represented where the first column contains the set of Azimuths and the second column the set of Dips.

  • A list (with two items) of elements to be represented where the first item contains the set of Azimuths and the second item the set of Dips.

  • An array of 2 values to be represented where the first value stands for the azimuth and the second one for the dip.

...

Arguments passed for the functions define.scenes, lines, segments, polygon, points or title.

mode

Type of respresentation:

  • 1 Schmidt Plot representing (optionally) the plane and its corresponding pole, or the position of a line.

  • 2 Rose diagram of the dipping angle

  • 3 Rose diagram of the dipping direction angle

radius

Radius of the circle of the Schmidt Diagram

ntick

Number of tick marks to be represented around the circle

nlabel

Number of labels to be represented regularly around the circle. The main angles are displayed using the letters "N", "E", "W", "S", whereas the secondary labels are displayed as angle values.

flag.pole

When mode=1, the pole is materialized by the projection of the dip on the unit sphere.

flag.plan

When mode=1, the plane is materialized by the half-ellipse representing the intersection of this plane with the unit sphere.

flag.line

When mode=1, the line (defined by the arguments 'azim' and 'dip' is drawn.

flag.back

When mode=1, the meridians and equator are represented systematically every 10 degrees. The color used is 'col0'.

opt.text

Type of pole representation:

  • 0 by a symbol

  • 1 by the numerical value of the gradient azimuth angle

  • 2 by the numerical value of the gradient dipping angle

nclass

Number of classes for the rose diagrams.

col

Color used for representing the azimuth circles, the dipping poles or the rose polygons.

col0

Color used to represent the meridians and parallel in background (option 'flag.back' used when 'mode'=1)

title

A character string representing the title.

add

TRUE to overlay on the previous contents of graphic; FALSE otherwise

reset

When TRUE, the screen is erased before the plot is performed.

verbose

When TRUE, the statistics per class of the rose diagram are printed out (valid only when mode=2 or 3)
