panel.cor.res: 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 coefficeint 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
