panel.cor.res {asbio}R Documentation

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
