trans_binary: Transform medical history by binarizing day interval

In herdiantrisufriyana/medhist: A preprocessor to construct medical history table from data source

Description

This function transforms each medical history from day interval to binary one. If there is no record, then the value is 0; otherwise, the value is 1.

Usage

trans_binary(tidy_set, verbose = T)

Arguments

tidy_set	A TidySet (i.e. ExpressionSet) containing the visits of subjects in outcome dataset, paid by any payment systems. This TidySet also accomodates outcome dataset. This is an output of compile_mh_outcome().
verbose	Verbosity, a logical indicating whether progress should be shown.

Value

A TidySet (i.e. ExpressionSet) containing the visits of subjects in medical history and the outcome datasets. Since a code may be encountered before db_start_date, causing the value returns NA to denote censored data, that medical history is transformed to 0. But, if the interval is 0, the value returns 1 because this means the record exists.

Examples

## Create input example
data(medhistdata)

## Transform medical history by binarizing day interval
mh_binary=trans_binary(medhistdata)
