panel.cor.res: Functions for customizing correlation matrices

Functions for customizing correlation matrices

Description

The functions here can be used to customize upper and lower triangles in correlation matrices. In particular panel.cor.res provides correlation coefficients (any alternative from cor can be used) and p-values for correlation tests. The function panel.lm puts linear fitted lines from simple linear regression in scatterplots. Note that the function panel.smooth provides a smoother fit.

Usage

panel.cor.res(x, y, digits = 2, meth = "pearson", cex.cor=1)
panel.lm(x, y, col = par("col"), bg = NA, pch = par("pch"), cex = 1,
col.line = 2,lty = par("lty"))

Arguments

x	variable 1 in correlation
y	variable 2 in correlation
digits	number of digits in text for panel.cor.res
meth	type of correlation coefficient from panel.cor.res, one of "pearson", "spearman", "kendall"
cex.cor	size of text in panel.lm
col	color of points in panel.lm
bg	background color of points in panel.lm
pch	type of symbols for points in panel.lm
cex	symbol size in panel.lm
lty	line type in panel.lm
col.line	color of lines in panel.lm
