maCompCoord: Generate grid and spot matrix coordinates

In marray: Exploratory analysis for two-color spotted microarray data

Description

This function generates grid and spot matrix coordinates from ranges of rows and columns for the grid and spot matrices. Spots on the array are numbered consecutively starting from the top left grid and the top left spot within each grid.

Usage

maCompCoord(grows, gcols, srows, scols)

Arguments

grows	numeric vector of grid rows.
gcols	numeric vector of grid columns.
srows	numeric vector of spot rows.
scols	numeric vector of spot columns.

Value

a matrix of spot four-coordinates, with rows corresponding to spots and columns to grid row, grid column, spot row, and spot column coordinates.
