Overview

About

Maintained by Lennon LiCRAN page ↗GitHub ↗Website ↗Issues ↗

Detects all R installations on the current machine and migrates installed R packages between them. Provides find_routes() to discover R versions, manifest() to scan package libraries in a child R process, inventory() to compare two libraries, and ship() to install packages into a target R version using 'pak'. Includes a Shiny dashboard (open_hub()) for interactive source-to-target migration.

Changes in 0.3.1

Bug fixes

Fixed a second cause of shipped packages never showing up as installed, on the *copy* path (offline/preserve modes and online mode's local/private packages). A manifest's libpath is the library directory shared by every package, but .copy_plan() passed it through as if it were the per-package source, so each "copy" recursively cloned the entire source library into target/<pkg>/ — leaving no valid package where R looks and reporting a silent success. The package name is now joined onto the library path, which also restores the cross-major compiled-package warning (its libs/ check was always false before). Covered by a .copy_plan + copy_packages regression test and an opt-in browser end-to-end test (COURIER_E2E=true).
R installation detection no longer drops installs intermittently on slow machines. find_routes() probed each candidate with a hard 3 s timeout and silently discarded any that exceeded it, so a cold R start (antivirus, OneDrive-synced installs) made versions flicker in and out between runs. The default probe timeout is now 30 s, configurable via options(courier.probe_timeout = ), and a probe that does time out is reported with a warning instead of vanishing; the rig list timeout was also raised from 5 s to 15 s.

Fixed shipped packages never showing up as installed: find_target_lib() and the pak install subprocess inherited the parent R session's R_LIBS_USER, so ship() installed into the *parent's* library while Compare scanned the real target. All subprocesses that launch another R now share one environment-stripping helper (child_r_env()), and the install destination is guaranteed to be a library that manifest() scans.
Library scans that time out are no longer cached as "empty library" for the rest of the session; timeouts are reported loudly in the log and the scan timeout was raised from 30 s to 5 min for slow machines.
The "both installations share one library" warning no longer fires vacuously when both scans returned no packages.

Routing

Online mode now means online: every package resolvable from CRAN / Bioconductor / GitHub is reinstalled via pak (binaries preferred). Only local/private packages with no online source are copied from the source library. (Previously pure-R CRAN packages were file-copied even in online mode, which is much slower than pak on synced/network libraries.)

Performance

One manifest scan per library per session, shared across all tabs: a ship right after Compare reuses the Compare scans and spawns no scan subprocesses; the post-ship refresh rescans only the shipped-into library.

Dashboard UX

**Bulk Dispatch** now shows a live hero panel during shipping (matching Custom Dispatch): packages delivered so far, the current package being installed, elapsed time, and the estimated total. The detailed log in the R console is also mirrored in the dashboard log pane.
Both **Bulk Dispatch** and **Custom Dispatch** tables now default to showing only packages missing from the target after Compare, instead of all diff statuses. The filter chip bar lets you toggle other statuses.
**Custom Dispatch** filter chips are now colour-coded — orange for source-side differences (newer in source, not in target), teal for target-side differences — matching Bulk Dispatch.
**Custom Dispatch** comparison table gains a **Repo** column showing where the package comes from (CRAN, Bioconductor, GitHub, etc.). Packages with an unknown source are shown in red in both tables.
report_issue() — new exported function. Call it from the console after any error to open a pre-filled GitHub issue form in your browser with your R version, platform, courieR version, and the error message already populated. The dashboard's error modal gains a **Send Report** button that does the same in one click.
Custom Dispatch shows a live green hero panel while shipping: packages delivered so far, the package currently being copied/installed, elapsed time, and the estimated total.
Time estimates (plan summary, ship confirmation, preview invoice) now come from per-machine calibrated rates persisted across sessions — every completed ship updates them — instead of fixed constants that were off by 100x on synced/network drives.
Custom Dispatch source/target header now shows the R version, install location, and library path of both installations (was the bare executable path).
After a Custom Dispatch shipment the comparison tables refresh automatically and the depot log says so; the refresh is logged when it completes.
library(courieR) startup message now includes a link to the user guide vignette (vignette("get-started", package = "courieR")).

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("courieR", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("lennon-li/courieR")

Development version from lennon-li/courieR. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-courier

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-courieR

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-courieR

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
