Stereographic Projection

Initialize the plot for equal-area 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
)

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

linewidth of guide lines

lty

linetype 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 stereoplot.

labels

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

ladj

adjustment for all labels away from origin of stereoplot 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
