Stereographic Projection of Lines and Planes

Visualization of lines, planes in a stereographic projection.

Usage

stereo_point(
  x,
  col = 1,
  pch = 20,
  lab = NULL,
  text.pos = 4,
  cex = 1,
  upper.hem = FALSE,
  earea = TRUE,
  ...
)

Arguments

x

object of class "Vec3", "Line", "Ray", "Plane", "Pair", or "Fault", where the rows are the observations and the columns are the coordinates.

col

color

pch

plotting character

lab

character. text labels

text.pos

position for labels

cex

character expansion of labels

upper.hem

logical. Whether the projection is shown for upper hemisphere (TRUE) or lower hemisphere (FALSE, the default).

earea

logical TRUE for Lambert equal-area projection (also "Schmidt net"; the default), or FALSE for meridional stereographic projection (also "Wulff net" or "Stereonet").

...

optional graphical parameters

Note

"Plane" and "Fault" objects will be displayed as pole to the plane (only).
