## 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)
