In usedthese: Summarises Package & Function Usage

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

To add a summary table of package & function usage to the foot of a Quarto document, add used_here() to the end of the code. A separate code chunk with an appropriate heading is suggested but not essential.

The package author recommends using the conflicted package to resolve conflicts. In the example below, 'dplyr' has been preferred over stats for filter() and over the xts package for last().

An alternative approach to using conflicted is to use the exclude or include.only argument in library(). This is also shown below with the xts version of first excluded and hence the dplyr version preferred.

Some code

options(tidyverse.quiet = TRUE)
options(xts.warn_dplyr_breaks_lag = FALSE)
library(conflicted)
library(dplyr)
library(tibble)
conflicts_prefer(dplyr::filter, dplyr::last)
library(usedthese)
library(xts, exclude = "first")

conflict_scout()

More code

tribble(~group, ~a1, ~a2, ~b1,
        "x", 1, 2, 3,
        "x", 4, 5, 6,
        "y", 7, 8, 9) |> 
  select(-starts_with("b")) |> 
  filter(group == "x") |> 
  mutate(first_a1 = first(a1),
         last_a2 = last(a2))

Summary of usage

In the example below, tribble() is counted once against the (originating) tibble package even though it is also loaded by dplyr. And had we not used the conflicted package, filter() for example would have shown against the package name "dplyr, stats".

The rendered table is assigned the CSS class .usedthese to help other used_* functions find and aggregate multiple tables across one or more websites.
