im_2_mat: Plot heatmaps of two matrices in red and blue

Description

Displays two heatmaps of matrices using red and blue colors. Options to scale and sort as well as any other graphical parameters with ... Sorting attempts to match columns between the two matrices using their correlation over rows. If sort==TRUE then the new ordering for the second matrix is returned.

Usage

im_2_mat(x1, x2, high = "red", xaxt = "n", yaxt = "n", scale = "col",
  absol = FALSE, sort = TRUE, center = FALSE, main1 = "", main2 = "",
  ...)

Arguments

x1

matrix

x2

matrix

high

string of either 'red' or 'blue' used to show higher values

xaxt

string indicating how to display the x axis. Suppress x axis with 'n'

yaxt

string indicating how to display the y axis. Suppress y axis with 'n'

scale

logical indicating whether the matrices should be z scaled to have columns with norm zero and standard deviation one.

absol

logical indicating whether to take absolute value of the entries before plotting

sort

logical indicating whether the columns of the matrix should be sorted in decreasing order of their means

center

logical indicating wether to center ranges for x and y around zero

main1

string to be used as the main title for the first matrix image

main2

string to be used as the main title for the second matrix image

...

other graphical parameters passed to image

Value

If sort==TRUE the ordering of the second matrix used to match columns.

Examples

# NOT RUN {
par(mfrow=c(1,2))
im_2_mat(matrix(1:12, nrow=3, ncol=4),  matrix(13:24, nrow=3, ncol=4), sort=FALSE, scale=FALSE)
im_2_mat(matrix(1:12, nrow=3, ncol=4),  matrix(13:24, nrow=3, ncol=4), sort=TRUE, scale=FALSE)
im_2_mat(matrix(1:12, nrow=3, ncol=4),  matrix(13:24, nrow=3, ncol=4), sort=TRUE, scale=TRUE)
im_2_mat(matrix(1:12, nrow=3, ncol=4),  matrix(13:24, nrow=3, ncol=4), sort=FALSE, 
         scale=FALSE, center=TRUE)
