The progressify package allows you to easily add progress
reporting to sequential and parallel map-reduce code by piping to the
progressify() function. Easy!
library(progressify)
handlers(global = TRUE)
library(fwb)
# Run fractional weighted bootstrap with progress signaling
my_stat <- function(data, w) coef(lm(mpg ~ cyl, data = data, weights = w))
res <- fwb(data = mtcars, statistic = my_stat, R = 1000) |> progressify()
This vignette demonstrates how to use this approach to add progress
reporting to the fwb package's main function fwb().
The fwb package provides functions for generating fractional weighted bootstrap replicates.
For example, fwb() runs a statistic function R times:
library(fwb)
my_stat <- function(data, w) coef(lm(mpg ~ cyl, data = data, weights = w))
res <- fwb(data = mtcars, statistic = my_stat, R = 1000)
By default, fwb() uses verbose = TRUE, which provides progress
feedback via the pbapply package, where the style can be
controlled via pbapply::pboptions().
As an alternative, we can use the progressify() function to report
on progress via any combination of progressr reporters. To do
this, use:
library(fwb)
library(progressify)
handlers(global = TRUE)
my_stat <- function(data, w) coef(lm(mpg ~ cyl, data = data, weights = w))
res <- fwb(data = mtcars, statistic = my_stat, R = 1000) |> progressify()
Comment: This will disable the built-in progress feedback by setting
verbose = FALSE in order to avoid dual reporting.
The progressify() function supports the following fwb
functions:
fwb()These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
