print_proposals: Print proposals

In stors: Step Optimised Rejection Sampling

Print proposals

Description

This function prints details of all proposals stored by the user. It provides information on each proposal, including the proposal name, size, efficiency, and other relevant details.

Usage

print_proposals()

Value

Prints a summary of all proposals, but does not return any value.

Examples

# First, let's create a proposal to sample from a standard normal distribution
f_normal <- function(x) { 0.3989423 * exp(-0.5 * x^2) }
normal_proposal = build_proposal(f = f_normal, modes = 0, lower = -Inf, upper = Inf, steps = 1000)
print(normal_proposal)

# `print_proposals()` prints all proposals stored in R's internal data directory.
# To see this, we first save `normal_proposal` using `save_proposal()`
save_proposal(normal_proposal, "normal")

# Since `normal_proposal` is now stored on this machine,
# we can confirm this by printing all saved proposals
print_proposals()

# Example 2: Create and Save a proposal for a Bimodal Distribution
f_bimodal <- function(x) {
  0.5 * (1 / sqrt(2 * pi)) * exp(-(x^2) / 2) +
  0.5 * (1 / sqrt(2 * pi)) * exp(-((x - 4)^2) / 2)
}
modes_bimodal = c(0, 4)
bimodal_proposal = build_proposal(f = f_bimodal, modes = modes_bimodal,
lower = -Inf, upper = Inf, steps = 1000)

save_proposal(bimodal_proposal, "bimodal")
print(bimodal_proposal)

# To print all stored proposals after saving bimodal_proposal
print_proposals()
