Create Correlation Matrix — correlation

This is a wrapper for languageR::pairscor.fnc. A matrix of scatter plots is produced with Pearson and Spearman correlations in the lower triangle. Fall back to the original function to specify additional arguments.

correlation_matrix(
  data,
  variables,
  hist = TRUE,
  smooth = TRUE,
  size = 1,
  color = "darkgrey"
)

Arguments

data	The data set containing the variables to be plotted.
variables	The variables used in the plot. Note: Variables cannot be of type 'character'.
hist	A logical indicating whether panels on the diagonal should contain a histogram.
smooth	A logical indicating whether panels in the upper triangle should have a smoother added.
size	A number indicating the size of the points in the panels in the upper triangle, available only when smoothers are added.
color	A number or string indicating the color of the points in the panels in the upper triangle, available only when smoothers are added.

Value

Nothing. Creates a plot.
