R/phi plot

R/phi plot

Usage

Rphi_plot(
  r,
  phi,
  contour = TRUE,
  image = FALSE,
  n = 10L,
  contour.lines = TRUE,
  contour.lines.params = list(lwd = 0.5, col = par("col")),
  contour.col = viridis,
  contour.col.params = list(),
  mean.ellipse = TRUE,
  mean.ellipse.method = "eigen",
  mean.ellipse.params = list(border = "red", lwd = 2),
  point.params = list(col = "grey", pch = 16, cex = 0.5),
  rmax = NULL,
  at.x = seq(-90, 90, 30),
  at.y = NULL,
  main = "Rf/phi plot",
  ...
)

Arguments

r

numeric. Aspect ratio of deformed object (long axis / short axis)

phi

numeric. Orientation of long axis of deformed object (in degrees)

contour

logical. Whether a grid of densities should be drawn in the background.

image

logical. Whether a raster image or filled contour lines should be drawn as density grid. Ignored when contour=FALSE

n

integer. Grid resolution or number of filled contours

contour.lines

logical. Whether contour lines should be added.

contour.lines.params

list of plotting arguments passed to graphics::contour()

contour.col

function to produce color palette used for contouring

contour.col.params

list of plotting arguments passed col.palette

mean.ellipse

logical. Whether the mean ellipse should be plotted

mean.ellipse.method

character. Whether the mean ellipse should be determined using the eigenvector method after Shimamoto and Ikeda, 1976 ("eigen", the default), or Ramsay's method using the geometric mean of min and max Rf values ("ramsay").

mean.ellipse.params

list of plotting arguments passed to ellipse()

point.params

list of plotting arguments passed to graphics::points()

rmax

maximum R value (if NULL, computed automatically)

at.x, at.y

the points at which tick-marks and labels for the x and y axes are to be drawn.

main

character. The main title (on top).

...

optional arguments passed to hypercontour()

Value
