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

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.
