This function portrays the row and column trends of the centred column profile matrix reconstructed by means of othogonal polynomials and/or principal axes.
trendplot(f, g, cex = 1, cex.lab = 0.8, main = " ", prop = 0.5,
posleg = "topleft", xlab = "First Principal Axis",
ylab = "Second Principal Axis")The row coordinates.
The column coordinates.
The parameter for setting the size of character labels of points in graphical displays. By default, cex = 1.
The parameter for setting the size of character labels of axes in graphical displays. By default, cex.lab = 0.8.
The title of the graphical display.
The scaling parameter for specifying the limits of the plotting area. By default, prop = 0.5.
The parameter for specifying the position of the legend in the graphical function trendplot.
By default, pos = "topleft".
The parameter for setting the character label of the horizontal axis in graphical displays.
