blacksheepr: Outlier Analysis for pairwise differential comparison

Blacksheep is a tool designed for outlier analysis in the context of pairwise comparisons in an effort to find distinguishing characteristics from two groups. This tool was designed to be applied for biological applications such as phosphoproteomics or transcriptomics, but it can be used for any data that can be represented by a 2D table, and has two sub populations within the table to compare.

Create the annotation object for plotting in a heatmap	annotationlist_builder
Create all of the groups based on the input metadata	comparison_groupings
Count up the outlier information for each of the groups you have made. If aggregating then you will have to turn the parameter on, but you still input the outliertable. Aggregate will count the total number of outliers AND nonoutliers in its operation, so it needs the original outlier table made by the <make_outlier_table> function.	count_outliers
Plot out a heatmap	create_heatmap
Run the entire blacksheep Function from Start to finish	deva
Normalization of data to prepare for deva. Uses a Median of Ratio method followed by a log2 transformation.	deva_normalization
Utility function that allows easier grabbing of data	deva_results
Utility function that will take in columns with several subcategories, and output several columns each with binary classifications. ex) col1: A,B,C >> colA: A,notA,notA; colB: notB,B,notB; colC: notC,notC,C	make_comparison_columns
Separate out the "i"th gene, take the bounds, and then create a column that says whether or not this gene is high, low, or none in a sample with regards to the other samples in the dataset. Repeat this for every gene to create a reference table.	make_outlier_table
With the grouptablist generated by count_outliers - run through and run a fisher exact test to get the p.value for the difference in outlier count for each feature in each of your comparisons	outlier_analysis
