plotFars | R Documentation |
Devices may be airbags or seatbelts. For airbags, alternatives are to use “airbag installed” or “airbag deployed” as the criterion. The plot shows, for each of the specified features, the ratio of driver death rate (or other outcome, e.g., death or injury) with feature, to rate without feature, in both cases for passenger without feature.
plotFars(tabDeaths=gamclass::frontDeaths,
statistics = c("airbagAvail", "airbagDeploy", "restraint"))
tabDeaths |
List, containing (as a minimum) three-dimensional arrays
with the names specified in the argument |
statistics |
Vector of character: names of the sublists, which contain information on the deathrates |
The name injury
is used, with frontDeaths
or sideDeaths
or rearDeaths
or otherDeaths
as the first argument, to refer to
deaths. The function tabFarsDeaths
allows the option of returning an
object, suitable for using as first argument, that treats injury
as
death or serious injury.
A graphics object is returned
Note that the “airbag deployed” statistic is not a useful measure of airbag effectiveness. At its most effective, the airbag will deploy only when the accident is sufficiently serious that deployment will reduce the risk of serious injury and/or accident. The with/without deployment comparison compares, in part, serious accidents with less serious accidents.
