corrGrid {corrViz}

Plot a correlation grid

Description

Create a correlation grid plot to visualize correlations among the columns of a dataset

Usage

corrGrid(
  mat,
  display = c("all", "upper", "lower"),
  type = c("square", "circle", "text", "pie"),
  showDiag = "TRUE",
  pal = colorRampPalette(c("darkblue", "white", "darkred"))(100)
)

Arguments

mat

A square correlation matrix to visualise.

display

A character string, specifying the display type, one of "all", "upper", or "lower" (default: "all").

type

A character string, specifying the shape of the correlation coefficients, one of "square", "circle", or "text" (default: "square").

showDiag

A logical value, if TRUE (default), the diagonal of the correlation matrix is shown.

pal

A color palette function, used for the correlation coefficient colors.

Value

A correlation grid plot

Examples

cm <- cor(mtcars)
corr_grid_plot <- corrGrid(mat = cm,
                           type = 'square')
