matrix.subset: Preserve matrix formatting when reformatting a matrix

In akeyel/myr: My R functions

Description

When a single column is extracted from a multicolumn matrix, R often strips the matrix formatting. This generally causes my code to crash, because I assume that the formatting is preserved. This function aims to preserve that formatting. Testing note: Tested with an input matrix with 5 columns & 4 rows, and subset to obtain 0, 1 and 2 columns.

Usage

matrix.subset(in.mat, index.var, target.value)

Arguments

in.mat	The input matrix
index.var	The variable to be used for subsetting
target.value	The value of the subsetting variable to subset on.
