View source: R/convertRawReports2Tables.R

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`

1	convertRawReports2Tables(reports, n_drugs, n_events)

`reports`	A binary matrix. Each row is a report
`n_drugs`	The number of drugs
`n_events`	The number of events

The code is a simplified version of the function create2x2Tables in the SRSim package.

A data frame where each row represents a 2 x 2 table. The columns represent:

`drug_id`	The ID of the drug
`event_id`	The ID of the event
`a`	Number of times the drug and event appeared together in a report
`b`	Number of times the event appeared without the drug in a report
`c`	Number of times the drug appeared without the event in a report
`d`	Number of times the drug and event both did not appear in a report
