Ternary plot of the matching between two sets of coordinates

This function represents a three dimensional scatter plot of paired coordinates.

Usage

triangle.match(dfxyz1, dfxyz2, labels = row.names(as.data.frame(dfxyz1)), 
  min3d = NULL, max3d = NULL, adjust = TRUE, showposition = TRUE, facets = NULL, 
  plot = TRUE, storeData = TRUE, add = FALSE, pos = -1, ...)

Arguments

dfxyz1: a three columns data frame, the first system of coordinates, used to produce the plot
dfxyz2: a three columns data frame, the second system of coordinates, with as many rows as dfxyz1, used to produce the plot.
labels: a vector of character strings containing the matches' labels
adjust: a logical to adjust the device with the limits of the smaller equilateral triangle containing the values
min3d: a vector of three values for triangular minimal limits
max3d: a vector of three values for triangular maximal limits
showposition: a logical indicating whether the used triangle should be shown in the complete one
facets: a factor splitting the rows of dfxyz so that subsets of the data are represented on different sub-graphics
plot: a logical indicating if the graphics is displayed
storeData: a logical indicating if the data are stored in the returned object. If FALSE, only the names of the data arguments are stored
add: a logical. If TRUE, the graphic is superposed to the graphics already plotted in the current device
pos: an integer indicating the position of the environment where the data are stored, relative to the environment where the function is called. Useful only if storeData is FALSE
...: additional graphical parameters (see adegpar and trellis.par.get)

Value

An object of class ADEg (subclass Tr.match) or ADEgS (if showposition is TRUE, if add is TRUE and/or if facets are used).
The result is displayed if plot is TRUE.
