scenarios: Create a number of scenarios based on a single observation

In DoktorMike/datools: A set of useful tools for machine learning consulting using R

Description

Most common use case is a data.frame full of observations and you want to simulate different values of a few variables while keeping the others fixed. This is important in models with interactions as well as non-linear models. The data.frame return from this function can go directly into a stats::predict call if the model being predicted on supports that interface.

Usage

scenarios(datapoint, varvals)

Arguments

datapoint	containing all variables that a scenarios needs in addition to the ones you want to manipulate
varvals	is a named list where each list item is a vector with all the values you would like to test for the named variable

Value

a tibble with all the combinations of the values you choose to change

Examples

scenarios(data.frame(A=0, B=4, C=6), varvals=list(B=c(2,3,6), A=c(1,7,9)))
