Stereographic and Equal Area Projection

Initialize the plot for equal-angle stereographic projections (Wulff) or Lambert equal-area projections (Schmidt).

Usage

stereoplot(
  earea = TRUE,
  guides = TRUE,
  d = 10,
  col = "gray90",
  lwd = 0.5,
  lty = 1,
  border.col = "black",
  title = NULL,
  sub = NULL,
  origin.text = "N",
  labels = FALSE,
  ladj = 0.05,
  centercross = TRUE,
  ticks = 90,
  radius = 1,
  center = NULL
)

Arguments

earea

logical. Projection, either TRUE for Lambert equal-area projection (the default), or FALSE for meridional stereographic projection.

guides

logical. Whether guides should be added to the plot (TRUE by default)

d

integer. Angle distance between guides. Default: 10

col

Color of guide lines

lwd

Width of guide lines

lty

Type of guide lines

border.col

color of primitive circle (frame), center-cross and ticks of the stereo plot

title, sub

character. Title and subtitle of plot

origin.text

character. Text at origin of plot

labels

this can either be a logical value specifying whether (numerical) annotations are to be made next to the tick marks, or a character or expression vector of labels to be placed next to the tick points.

ladj

adjustment for all labels away from origin of projection circle. This essentially an amount that is added to radius and the length of the ticks.

centercross

logical. Whether a center cross should be added (TRUE by default)

ticks

integer. Angle between ticks. if NULL (the default), no ticks are drawn.

radius

numeric. Radius of circle

center

An object of class "Vec3", "Line", "Ray", or "Plane" specifying the center of the projection If NULL (the default), the center is at the origin of the plot.
