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))
