Filter Module

The filter module provides an interface to select a data set, variable, and a query based on the value.

Format

R6 class

Input

datalist

A list of data sets. Can be tibbles, data frames, etc. Expects them to have a common ID field (default is USUBJID)

options

The options for the module of type reactiveValues with values

expanded

Should the accordion be expanded when created? Default: TRUE

subjectDs

If one of the data sets in datalist contains subject level data then provide it here. Default: ADSL

idvar

ID field that is common across all datasets in input:datalist. Default USUBJID

Output

filter

S3 object DatasetFilter
