Heatmap correlation matrix with ggplot2

Description

Heatmap correlation matrix with ggplot2

Usage

GG_heatmap(
  data,
  add_values = T,
  reorder_vars = T,
  digits = 2,
  font_size = 4,
  color_label = "Pearson\nCorrelation",
  legend_position = c(0.4, 0.7),
  short_x_labels = F,
  axis_labels_clean_func = str_clean,
  dodge_x_labels = 1,
  min_n = 0,
  pairwise_n = NULL
)

Arguments

data	Data frame or a matrix
add_values	Whether to add the correlation sizes as text to plot
reorder_vars	Whether to reorder variables so strongly related ones are close to each other
digits	How many digits to print when plotting them
font_size	If correlation values are plotted, their size
color_label	Which label to use for the color scale legend
legend_position	Position of the legend. Sometimes you may need to move it a bit
short_x_labels	Adds integers to the y axis labels, and replaces the x labels with the same integers. Useful when there are many variables.
axis_labels_clean_func	A function to clean the labels with, typically to remove underscores. NULL means disable.
dodge_x_labels	How much to dodge the x labels. Useful when there are many variables.
min_n	Minimum number of observations to include a correlation

Value

a ggplot2 object
