Create a simulation data set from ev objects

Description

The goal is to take a series of event objects and combine them into a single data set that can be passed to data_set().

Usage

as_data_set(x, ...)

## S4 method for signature 'ev'
as_data_set(x, ...)

## S4 method for signature 'data.frame'
as_data_set(x, ...)

Arguments

Details

Each event object is added to the data frame as an ID or set of IDs that are distinct from the IDs in the other event objects. Note that including ID argument to the ev() call where length(ID) is greater than one will render that set of events for all of IDs that are requested.

To get a data frame with one row (event) per ID, look at expand.ev().

Value

A data frame suitable for passing into data_set().

Examples

as_data_set(ev(amt = c(100,200), cmt=1, ID = seq(3)),
            ev(amt = 300, time = 24, ID = seq(2)),
            ev(amt = 1000, ii = 8, addl = 10, ID = seq(3)))

# Instead of this, use expand.ev
as_data_set(ev(amt = 100), ev(amt = 200), ev(amt = 300))
