In debarros/dbTools: Functions From de Barros

Description

Given two numeric matrices with equal dimensions, create a matrix of max values of corresponding cells and apply row and column names. NA's are only returned if both matrices have NA in the same cell.

Usage

CreateCompareMatrix(studentlist, Exams, matrix1, matrix2)

Arguments

studentlist	A vector of row names
Exams	A vector of column names
matrix1	A numeric matrix
matrix2	A numeric matrix with the same dimensions as matrix1

Value

A numeric matrix with the same dimensions as the input matrices

Examples

s1 = LETTERS[1:5]
E1 = c("Math", "Science", "History")
m1 = matrix(sample(100, 15, F), 5)
m2 = matrix(c(NA, 7*(1:14)), 5)
m3 = matrix(c(NA, NA, 100 - 7*(1:13)), 5)
CreateCompareMatrix(s1, E1, m1, m2)
CreateCompareMatrix(s1, E1, m1, m3)
CreateCompareMatrix(s1, E1, m2, m3)
