as_data_set | R Documentation |
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()
.
as_data_set(x, ...)
## S4 method for signature 'ev'
as_data_set(x, ...)
## S4 method for signature 'data.frame'
as_data_set(x, ...)
x |
ev objects |
... |
more ev objects |
Each event object is added to the data frame as an ID
or set of ID
s
that are distinct from the ID
s 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 ID
s 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()
.
A data frame suitable for passing into data_set()
.
expand.ev()
, ev()
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))
