correlationHeatmap: Plot a Heatmap for a Correlation Matrix

In rettopnivek/utilityf: Useful Functions for Modeling and Plotting

Description

Generates a heatmap of the upper triangle of a correlation matrix.

Usage

correlationHeatmap(
  df,
  ttl = "Correlation matrix",
  labels = NULL,
  new = T,
  lyt = NULL,
  gradient = c("orange", "blue"),
  txtSz = 1.25,
  mc_adjust = "BH",
  cut_off = 0.05,
  H = 20/3,
  W = 25/3
)

Arguments

df	a data frame with all variables to include in the correlation matrix.
ttl	an optional title for the figure.
labels	the labels for the rows/columns.
new	logical; if TRUE generates a new plotting window.
lyt	an optional matrix specifying the layout of the main panel (1) versus the side panel (2) with the color gradient.
gradient	the final end colors for the negative and positive correlations, respectively.
txtSz	the size of the text in the figure.
mc_adjust	the method to use when correcting for multiple comparisons (see ).
cut_off	cut-off for significance.
H	the height to use if a new plotting window is generated.
W	the width to use if a new plotting window is generated.

Value

A heatmap for the upper-triangle portion of the correlation matrix.

Examples

# Load data
data("mtcars")
my_data <- mtcars[, c(1,3,4,5,6,7)]
# Generate heatmap
correlationHeatmap( my_data, labels = colnames(my_data) )
