expand_design easily generates a set of design from a designer function.

expand_design(designer, ..., expand = TRUE, prefix = "design")

Arguments

designer

a function which yields a design

...

Options sent to the designer

expand

boolean - if true, form the crossproduct of the ..., otherwise recycle them

prefix

prefix for the names of the designs, i.e. if you create two designs they would be named prefix_1, prefix_2

Value

if set of designs is size one, the design, otherwise a `by`-list of designs. Designs are given a parameters attribute with the values of parameters assigned by expand_design.

Examples

if (FALSE) { # in conjunction with DesignLibrary library(DesignLibrary) designs <- expand_design(multi_arm_designer, outcome_means = list(c(3,2,4), c(1,4,1))) # with a custom designer function designer <- function(N) { pop <- declare_model( N = N, U = rnorm(N), potential_outcomes(Y ~ 0.20 * Z + U) ) assgn <- declare_assignment(Z = complete_ra(N, m = N/2)) inquiry <- declare_inquiry(ATE = mean(Y_Z_1 - Y_Z_0)) estimator <- declare_estimator(Y ~ Z, inquiry = inquiry) pop + pos + assgn + inquiry + estimator } # returns list of eight designs designs <- expand_design(designer, N = seq(30, 100, 10)) # diagnose a list of designs created by expand_design or redesign diagnosis <- diagnose_design(designs, sims = 50) # returns a single design large_design <- expand_design(designer, N = 200) diagnose_large_design <- diagnose_design(large_design, sims = 50) }
