`axistetra.Rd`

Plots reference x, y and z arrows showing the direction of the axes in a static tetrahedral colorspace plot.

axistetra(x = 0, y = 1.3, size = 0.1, arrowhead = 0.05, col = par("fg"), lty = par("lty"), lwd = par("lwd"), label = TRUE, adj.label = list(x = c(0.003, 0), y = c(0.003, 0.003), z = c(0, 0.003)), label.cex = 1, label.col = NULL)

x, y | position of the legend relative to plot limits (usually a value between 0 and 1, but because of the perspective distortion, values greater than 1 are possible) |
---|---|

size | length of the arrows. Can be either a single value (applied for x, y and z) or a vector of 3 separate values for each axis. |

arrowhead | size of the arrowhead. |

col, lty, lwd | graphical parameters for the arrows. |

label | logical, include x, y and z labels (defaults to TRUE). |

adj.label | position adjustment for the labels. a list of 3 named objects for x, y and z arrows, each with 2 values for x and y adjustment. |

label.cex, label.col | graphical parameters for the labels. |
