Introduction to the graphic library

Usage:	`plotsplom (x {, option {, col {, xn {, xncol}}}})`
Input:
	`x`	n x p matrix
	`option`	scalar
	`col`	color
	`xn`	m x p matrix
	`xncol`	color

Note:

option[1,1] allows some transformation on x: grc.prep.inter -1 interactive selection grc.prep.none 0 no transformation (default) grc.prep.standard 1 standardize grc.prep.zeroone 2 to [0,1] grc.prep.pcacov 3 pca on cov matrix grc.prep.pcacorr 4 pca on corr matrix grc.prep.sphere 5 sphering

option[2,1] decides about the plot on the diagonal: grc.prep.inter -1 interactive selection grc.splom.none 0 empty grc.splom.boxplotx 1 boxplot x grc.splom.boxploty 2 boxplot y (default) grc.splom.dotplotx 3 dotplot x grc.splom.dotplotx 4 dotplot y grc.splom.qqnplot 5 qqplot with normal distribution

Example:

; loads the library plot library("plot") ; reads the swiss banknote data(200x6) x = read("bank2") ; computes the principal components of x as scatterplot matrix plotsplom(x, grc.prep.pcacov)

Result:

shows the principal components in a scatterplotmatrix
