cbind_smother: Combine matrices by columns, replacing matching ones and adding unique ones

Description

This is like base::cbind() but if a column in the second matrix has the same name as a column in the first matrix, the column in the first matrix is deleted and that in the second matrix is used in its place.

Usage

cbind_smother(mat1, mat2)

Value

The two matrices combined by columns, but columns in the first matrix that also appear in the second matrix are deleted and replaced by those in the second matrix. Uses the row names to align the rows in the two matrices, and to expand them as needed.

Arguments

mat1

A matrix

mat2

Another matrix, with the same number of rows as mat.

Examples

df1 <- data.frame(x=c(1,2,3,NA,4), y=c(5,8,9,10,11), row.names=c("A", "B", "C", "D", "E"))
df2 <- data.frame(z=c(7,8,0,9,10), y=c(6,NA,NA,9,10), row.names=c("A", "B", "F", "C", "D"))
df1n2 <- cbind_smother(df1, df2)
