corByRownames: Calculate correlation coefficients using common rows of the two matrices

Description

Calculate correlation coefficients using common rows of the two matrices

Usage

corByRownames(mat1, mat2, ...)

Value

A matrix of the dimension \(m \times n\), where m and n are number of columns in mat1 and mat2, respectively. The matrix has an attribute, commonRownames, giving the common rownames shared by the two matrices.

Arguments

mat1

A numeric matrix

mat2

Another numeric matrix

...

Passed cor At least two rows of both matrices must share the same names, otherwise the function will report an error.

Examples

myMat1 <- matrix(rnorm(24), nrow=6, byrow=TRUE,
  dimnames=list(sprintf("R%d", 1:6), sprintf("C%d", 1:4)))
myMat2 <- matrix(rnorm(35), nrow=7, byrow=TRUE,
  dimnames=list(sprintf("R%d", 7:1), sprintf("C%d", 1:5)))
corByRownames(myMat1, myMat2)
