7  Development Version

Readers are strongly advised to update their packages from the Comprehensive R Archive Network (CRAN) as frequently as possible.

Listing 7.1: Update packages from CRAN

utils::update.packages()

To reproduce all examples in this Quarto book, readers must install the development versions of

1. these packages (Listing 7.2) from Tingting Zhan’s Github repository;
2. the spatstat.* family of packages (Listing 7.3) from spatstat Github repository.

by either of following approaches

• repeat Listing 7.4 until all calls print the message of “No downloads are needed”; or
• repeat Listing 7.5 until all calls print the message of “the SHA1 has not changed since last install”.

Listing 7.2: Development versions of Tingting Zhan’s packages

tzhan. = c(
  'groupedHyperframe', 'groupedHyperframe.random', 
  'hyper.gam', 'maxEff'
)
tzhan = tzhan. |>
  sprintf(fmt = 'tingtingzhan/%s')

Listing 7.3: Development versions of spatstat.* packages (Baddeley and Turner 2005; Baddeley, Rubak, and Turner 2015)

spatstat. = c(
  'spatstat.data', 'spatstat.explore', 'spatstat.geom', 
  'spatstat.linnet', 'spatstat.model', 'spatstat.random',
  'spatstat.sparse', 'spatstat.univar', 'spatstat.utils',
  'spatstat'
)
spatstat = spatstat. |>
  sprintf(fmt = 'spatstat/%s')

Listing 7.4: Install Listing 7.2 and Listing 7.3 using package pak (Csárdi and Hester 2025)

c(spatstat, tzhan) |>
  lapply(FUN = pak::pak, ask = FALSE)

Listing 7.5: Install Listing 7.2 and Listing 7.3 using package remotes (Csárdi et al. 2024)

c(spatstat, tzhan) |>
  lapply(FUN = remotes::install_github, upgrade = 'always')

Listing 7.6 - Listing 7.7 track of the development versions of these packages (Listing 7.2) and the spatstat.* family of packages (Listing 7.3) on Github and the stable releases on CRAN.

Listing 7.6: Development version of these packages (Listing 7.2)

cran = 'https://cran.r-project.org/web/packages/packages.rds' |>
  url() |> readRDS() |> # ?utils::available.packages does not get Date
  groupedHyperframe::rds2versiondate(pkg = tzhan., format = '%Y-%m-%d')
github = installed.packages(fields = 'Date') |> 
  groupedHyperframe::rds2versiondate(pkg = tzhan., format = '%Y-%m-%d')
merge.data.frame(
  x = cran, y = github, by = 'Package', sort = FALSE, 
  suffixes = c(' on CRAN (Stable)', ' on Github (Development)')) |> 
  knitr::kable(
    row.names = FALSE,
    caption = Sys.time() |> format(usetz = TRUE) |> 
      sprintf(fmt = 'Development version of *these packages* (%s)')
  )

Table 7.1: Development version of these packages (2026-02-12 10:37:03 EST)

Package	Version on CRAN (Stable)	Version on Github (Development)
groupedHyperframe	0.3.4	0.3.4
groupedHyperframe.random	0.2.2	0.2.2
hyper.gam	0.2.2	0.2.2
maxEff	0.2.2	0.2.2

Listing 7.7: Development version of spatstat.* family (Listing 7.3) ahead of CRAN

  )
