mind: subsets matrices, keeping the dimensionality intact

In flynnzac/kiam: Keep It A Matrix

Description

When you subset a matrix or data frame and the condition ends up only grabbing one row, R returns a vector instead of a matrix with one row. This function returns a matrix with one row.

Usage

mind(x, rows = NULL, cols = NULL)

Arguments

x	the matrix or data frame to subset
rows	either a vector of row indicies or a logical vector giving which rows to select from x
cols	either a vector of column indicies or a logical vector giving which rows to select from x

Value

a matrix subsetted to include only the rows and columns indicated but with its dimensionality preserved.
