trendplot {CAvariants}

Trends of matrix rows and columns

Description

This function portrays the row and column trends of the centred column profile matrix reconstructed by means of othogonal polynomials and/or principal axes.

Usage

trendplot(f, g, cex = 1, cex.lab = 0.8, main = " ", prop = 0.5, 
posleg = "right", xlab = "First Axis", 
ylab = "Second Axis")

Arguments

f

The row coordinates.

g

The column coordinates.

cex

The parameter for setting the size of character labels of points in graphical displays. By default, cex = 1.

cex.lab

The parameter for setting the size of character labels of axes in graphical displays. By default, cex.lab = 0.8.

main

The title of the graphical display.

prop

The scaling parameter for specifying the limits of the plotting area. By default, prop = 0.5.

posleg

The parameter for specifying the position of the legend in the graphical function trendplot. By default, pos = "right".

xlab

The parameter for setting the character label of the horizontal axis in graphical displays.

ylab

The parameter for setting the character label of the vertical axis in graphical displays.

Note

This function is called from the main plot function plot.CAvariants.
