align_matrices: Align the rows and columns of two (or more) matrices

In cmapR: CMap Tools in R

Description

Align the rows and columns of two (or more) matrices

Usage

align_matrices(m1, m2, ..., L = NULL, na.pad = TRUE, as.3D = TRUE)

Arguments

m1	a matrix with unique row and column names
m2	a matrix with unique row and column names
...	additional matrices with unique row and column names
L	a list of matrix objects. If this is given, m1, m2, and ... are ignored
na.pad	boolean indicating whether to pad the combined matrix with NAs for rows/columns that are not shared by m1 and m2.
as.3D	boolean indicating whether to return the result as a 3D array. If FALSE, will return a list.

Value

an object containing the aligned matrices. Will either be a list or a 3D array

Examples

# construct some example matrices
m1 <- matrix(rnorm(20), nrow=4)
rownames(m1) <- letters[1:4]
colnames(m1) <- LETTERS[1:5]
m2 <- matrix(rnorm(20), nrow=5)
rownames(m2) <- letters[1:5]
colnames(m2) <- LETTERS[1:4]
m1
m2

# align them, padding with NA and returning a 3D array
align_matrices(m1, m2)

# align them, not padding and retuning a list
align_matrices(m1, m2, na.pad=FALSE, as.3D=FALSE)
