Convert Reports to 2 x 2 Tables

Description

Creates a data frame containing all 2 x 2 contingency tables given a raw spontaneous reporting (SR) data set. An SR data set is a binary matrix, where each row is a report. The first columns represent the presence (1) or absence of a drug (0), the other columns represent the presence or absence of an event.

The tables are organized as follows:

	event j	not event j	total
drug i	a	c	a + c
not drug i	b	d	b + d
total	a + b	c + d	n_reports

Usage

n_drugs	The number of drugs
n_events	The number of events
