d.blast | R Documentation |
Blasting causes tremor in buildings, which can lead to damages. This dataset shows the relation between tremor and distance and charge of blasting.
data("d.blast")
A data frame with 388 observations on the following 7 variables.
date
date in Date format
location
Code for location of the building,
loc1
to loc8
device
Number of measuring device, 1 to 4
distance
Distance between blasting and location of measurement
charge
Charge of blast
tremor
Tremor energy (target variable)
The charge of the blasting should be controled in order to
avoid tremors that exceed a threshold.
This dataset can be used to establish the suitable rule:
For a given distance
, how large can charge
be in order
to avoid exceedance of the threshold?
