correlation matrix chart

Source: R/chart.Correlation.R
chart.Correlation.Rd

Visualization of a Correlation Matrix. On top the (absolute) value of the correlation plus the result of the cor.test as stars. On bottom, the bivariate scatterplots, with a fitted line. When the method parameter is set to "spearman" or "kendall", the lower panel scatterplots are automatically transformed to plot the monotonically ranked data rather than the raw values, providing visual alignment with the evaluated correlation method.

Usage

chart.Correlation(
  R,
  histogram = TRUE,
  method = c("pearson", "kendall", "spearman"),
  pch = 1,
  ...
)

Arguments

R

data for the x axis, can take matrix,vector, or timeseries

histogram

TRUE/FALSE whether or not to display a histogram

method

a character string indicating which correlation coefficient (or covariance) is to be computed. One of "pearson" (default), "kendall", or "spearman", can be abbreviated.

pch
