A Collection of Useful Functions by John

A set of general functions that I have used in various projects and other R packages. Miscellaneous operations on data frames, matrices and vectors, ROC and PR statistics.

A set of miscellaneous functions that I have used in various projects and in other R packages. Some of the most important are:

• powerset_icounts(): find common (patient) ids in incomplete multi-omic datasets
• get_roc_stats(): the ROC statistics the way you want it!
• pr.test(): compare two PR curves (AUCs) and get a p-value!
• pr.boot(): bootstrap CIs for PR curve
• partial_permut(): get a partially-scrambled vector (you choose how much!)
• normalize_to_range(): normalize a vector to a specified range
• dec_to_bin(): convert a decimal (base-10) number to its binary representation
• get_percentage_of_matches(): find the percentage of common elements between two vectors
• outersect(): find the non-common elements between two vectors (outer-section!)
• colors.100: a vector of 100 as much as possible distinct colors
