Produce Pairwise Scatterplots from an 'lda' Fit

Description:

     Pairwise scatterplot of the data on the linear discriminants.

Usage:

     ## S3 method for class 'lda':
     pairs(x, labels = colnames(x), panel = panel.lda,
          dimen, abbrev = FALSE, ..., cex=0.7, type = c("std", "trellis"))

Arguments:

       x: Object of class '"lda"'. 

  labels: vector of character strings for labelling the variables. 

   panel: panel function to plot the data in each panel. 

   dimen: The number of linear discriminants to be used for the plot;
          if this exceeds the number determined by 'x' the smaller
          value is used. 

  abbrev: whether the group labels are abbreviated on the plots. If
          'abbrev > 0' this gives 'minlength' in the call to
          'abbreviate'. 

     ...: additional arguments for 'pairs.default'. 

     cex: graphics parameter 'cex' for labels on plots. 

    type: type of plot. The default is in the style of 'pairs.default';
          the style '"trellis"' uses the Trellis function 'splom'. 

Details:

     This function is a method for the generic function 'pairs()' for
     class '"lda"'. It can be invoked by calling 'pairs(x)' for an
     object 'x' of the appropriate class, or directly by calling
     'pairs.lda(x)' regardless of the class of the object.
