earplanes: Draws planes on an equal area stereonet

In StratigrapheR: Integrated Stratigraphy

Draws planes on an equal area stereonet

Description

Draws planes on an equal area stereonet (modified from RFOC package)

Usage

earplanes(
  strike,
  dip,
  quadrant = NA,
  hsphere = "l",
  ndiv = 10,
  a = list(col = "black", lwd = 1),
  l = list(lty = 1),
  u = list(lty = 3),
  output = FALSE,
  plot = TRUE,
  xh = "WE",
  unique = TRUE
)

Arguments

strike	strike of the data; it is the angle from the north of the horizontal line of the plane. It is corrected by the dipfix function.
dip	dip of the data; it is the angle from the horizontal taken on the line of the plane perpendicular to the one of the strike. It is corrected by the dipfix function.
quadrant	the quadrant were the plane dips downward. Accepted values are NA, 'N', 'S', 'W' or 'E' (lower- or uppercase alike) for correction by the dipfix function.
hsphere	the hemisphere onto which to project the data. Either "b" for both, "l" for lower, and u" for upper.
ndiv	the number of intervals between each 10° (in declination)
a, l, u	list of graphical parameters to feed lines() for the all lines, or for the lines of the upper (u) and lower (l) hemisphere (the two latter override a). See ?lines help page for the possible arguments. See ?merge_list for further information.
output	whether to return an output (position of the points making the lines in the stereographic projection)
plot	whether to plot
xh	orientation of the x axis: can be 'WE' or 'SN'.
unique	whether to only plot each similar plan once.

Value

the x,y coordinates of each projected plane
