Stereographic projection — stereoplot • structr

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

Usage

stereoplot(
  earea = TRUE,
  guides = TRUE,
  d = 10,
  col = grDevices::gray(0.9),
  lwd = 1,
  lty = 1,
  border.col = "black",
  title = NULL,
  sub = NULL,
  origin.text = "N",
  labels = FALSE,
  ladj = 0.04,
  centercross = TRUE,
  ticks = NULL,
  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

Examples

stereoplot(ticks = 30, title = "title", sub = "subtitle", border.col = "purple", labels = TRUE)
