Correlation panel for pairs.

Description

This is a function that can be passed to pairs to visually depict the correlation coefficient and its significancy.

Usage

panel.cor(x, y, digits = 2, 
    prefix = "", cex.cor = NULL, 
    method = c("pearson", 
        "spearman", "spearmanExact", 
        "lm", "glmPoisson"), 
    n.adjust = 1, col.coef = "black", 
    col.signif = "red", 
    dbg = 0, ...)

Arguments

x	x data
y	y data
digits	number of significant digits in the reported correlation coefficients
prefix	prefix to be shown in front of correlation coefficients
cex.cor	magnification for the correlation coefficients and its significance (if NULL, is computed automatically and scaled proportionally to the significance)
method
n.adjust	number of tests to adjust P-values to
col.coef	color of coefficient
col.signif	color of significance flags
dbg	debug level
...	other arguments (ignored currently)

Examples

pairs(iris,
  upper.panel = function(x,y,..) panel.cor(x, y, n.adjust = ncol(iris) * (ncol(iris) - 1) / 2),
  lower.panel = points)
