Changes in version 1.3.1 - Added newly published paper. Changes in version 1.3.0 Development version in Bioconductor 3.18 Changes in version 1.1.2 BUG FIXES - Fixed documentation of argument jitter in TIS() and simulate_background_cells(). - Fixed incorrectly plotted image in README. Changes in version 1.1.1 SIGIFICANT USER CHANGE - simulate_background_cells() added an option (method = "Even") to simulate evenly spaced background images. This change is accompanied with addition of two parameters, method - to choose the background cell distribution and jitter - the parameter to simulate evenly spaced background cells. Tutorials and function TIS() were modified accordingly. Changes in version 0.99.5 SIGNIFICANT USER CHANGE - TIS() only plots one plot when arg plot_image is TRUE. Changes in version 0.99.4 SIGNIFICANT USER CHANGE - Added an optional parameter plot_image to simulate_background_cells(). Changes in version 0.99.3 NO SIGNIFICANT CHANGE Changes in version 0.99.2 NEW FEATURES - Added utils.R file to store internal functions. SIGNIFICANT USER-VISIBLE CHANGES - Updated the main object class from SingleCellExperiment to SpatialExperiment. - Changed the parameter Phenotype to Cell.Type. Changes in version 0.99.1 NEW FEATURES - Added parameter validity checks. SIGNIFICANT USER-VISIBLE CHANGES - Improved parameter descriptions. BUG FIXES - None Changes in version 0.99.0 NEW FEATURES - This is the first version of spaSim.
