This package contains helper functions for the Screenmill R package. Screenmill is designed to quantify colony growth experiments for Synthetic Genetic Arrays (SGA), Epistatic Mini-Array Profiling (E-MAP), Selective Ploidy Ablation (SPA), or a simple quantitative colony fitness assay. The Screenmill.grid package provides functions for the manipulation of image crop coordinates and grid placements for images that fail automatic processing.
This package can be installed from GitHub by following the instructions below.
