impimp_event {impimp}

Imprecise Events

Description

Helper function to allow the generation of a set of events as cartesian product.

Usage

impimp_event(..., isEventList = FALSE)

is.impimp_event(x)

Arguments

...

these arguments are of the form varname = value. For each component the varname should be a variable name from the underlying data.frame and value a vector of possible outcomes; may also be of length one.

isEventList

logical; if TRUE and ... contains only a list object, this list is treated as if it was an event specification, see .... Since this argument follows ... its name cannot be abbreviated.

x

object to test for class "impimp_event"

Value

A object of class "impimp_event" as a list of lists, where each sublist contains one point in the cartesian product, spanned by the input values and variables.

Note

There is no plausibility check on whether the supplied varnames are actually contained in the data.frame for which the resulting impimp_event object is later used for.

Examples

## underlying data set: x1: 1:6, x2: 1:10

## subspace, requiring: x1 == 1 & ((x2 == 1 ) | (x2 == 2))
impimp_event(x1 = 1, x2 = c(1,2))

## subsapce containing all points whitin the Cartesian
## product of (x1 =) {1,2,3,6} x {5,8} (= x2)
# via  ... argument
impimp_event(x1 = c(1:3,6), x2 = c(5,8))
# via EVENTLIST
impimp_event(list(x1 = c(1:3,6), x2 = c(5,8)),
             isEventList = TRUE)
