Produces a static 3D tetrahedral plot.

tetraplot(tcsdata, theta = 45, phi = 10, perspective = FALSE,
  range = c(1, 2), r = 1e+06, zoom = 1, achro = TRUE,
  achro.col = "grey", achro.size = 1, achro.line = FALSE,
  achro.lwd = 1, achro.lty = 3, tetrahedron = TRUE, vert.cex = 1,
  vert.range = c(1, 2), out.lwd = 1, out.lcol = "darkgrey",
  margin = c(0, 0, 0, 0), type = "p", labels = FALSE, ...)



(required) a data frame, possibly a result from the colspace or tetraspace function, containing values for the 'x', 'y' and 'z' coordinates as columns (labeled as such).


angle to rotate the plot in the xy plane (defaults to 45).


angle to rotate the plot in the yz plane (defaults to 10).


logical, should perspective be forced by using point size to reflect distance from the plane of view? (defaults to FALSE)


vert.range multiplier applied to cex and vert.cex, respectively, to indicate the size range variation reflecting the distance from the plane of view.


the distance of the eyepoint from the center of the plotting box. Very high values approximate an orthographic projection (defaults to 1e6). See persp for details.


zooms in (values greater than 1) or out (values between 0 and 1) from the plotting area.


logical. Should the achromatic center be plotted? (defaults to TRUE)

achro.col, achro.size, achro.lwd, achro.lty

graphical parameters for the achromatic coordinates.


logical. Should the achromatic line be plotted? (defaults to FALSE)


logical. Should the tetrahedron be plotted? (defaults to TRUE)


size of the points at the vertices (defaults to 1).

out.lwd, out.lcol

graphical parameters for the tetrahedral outline.


vector of four numbers specifying drawing margins (defaults to c(0, 0, 0, 0)).


accepts a vector of length 1 or 2 with 'p' for points and/or 'l' for lines from the point to the base of the tetrahedron.


logical. Should the name of each cone be printed next to the corresponding vertex?


tetraplot creates a 3D plot.
