Easily plot a matrix as an heatmap using ggplot2

Description

Easily plot a matrix as an heatmap using ggplot2

Usage

tgplot_heatmap(
  mtrx,
  col_names = NULL,
  row_names = NULL,
  xlab = NULL,
  ylab = NULL,
  plot_top = TRUE,
  plot_right = TRUE,
  interleave = FALSE,
  col_names_orient = c("horizontal", "vertical", "slanted"),
  col_names_color = "black"
)

Arguments

mtrx	The matrix to be plotted
col_names	The names that will be used as the X-axis labels. A NULL (the defualt) indicates that the original matrix colnames are used. A FALSE indicates that no X-axis labels should be displayed.
row_names	The names that will be used as the Y-axis labels. A NULL (the defualt) indicates that the original matrix rownames are used. A FALSE indicates that no Y-axis labels should be displayed.
xlab	The X-axis label
ylab	The Y-axis label
plot_top	Whether to put the X-axis labels at the top of the heatmap (as well as at the bottom)
plot_right	Whether to put the Y-axis labels at the right side of the heatmap (as well as at the left hand side)
interleave	Plot the odd Y-Axis labels on the left side and the even on the right side
col_names_orient	Orientation of the X-axis label
col_names_color	color of the column names

Value

ggplot object with the matrix plot

Examples

tgplot_heatmap(as.matrix(mtcars))
