as_data_set: 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 ev
as_data_set(x, ...)
# S4 method for data.frame
as_data_set(x, ...)

Value

A data frame suitable for passing into data_set().

Arguments

x

ev objects

...

more ev objects

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.

When determining the case for output names, the case attribute for the first ev object passed will be used to set the case for the output data.frame.

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

Examples

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

as_data_set(a, b, c)

d <- evd(amt = 500)

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