expandAsMatrix: expandAsMatrix

Description

Expand scalar or vector to a matrix.

Usage

expandAsMatrix(x, dim=NULL, byrow=TRUE)

Arguments

x
scalar, vector or matrix. If a vector, length must match one of the output dimensions.
dim
required dimension for the output matrix.
byrow
logical. Should the matrix be filled by columns or by rows (the default) if the length of the input vector is equal to both dimensions?

Value

Numeric matrix of dimension dim.

Details

This function expands a row or column vector to be a matrix. It is used internally in edgeR to convert offsets to a matrix.
