Overview

About

Maintained by R. Wayne OldfordCRAN page ↗GitHub ↗Website ↗Issues ↗

An extendable toolkit for interactive data visualization and exploration.

Changes in 1.4.3

now works in Tcl 8.6 and Tcl 9.0.1
changes are *many* to the base loon tcl code. Mostly
to be more careful about namespaces, Tcl 9 is stricter
to be more careful with math function changes in Tcl 9
bugs in image_scale.tcl fixed; imageviewer code cleaned up
in R code, changes to
onLoad.R file to remove checking based on .withTclImg All dependent packages should remove any reference to loon:::.withTclImg
l_image_import_files() now checks if tcl library tk image extension (Img) is available at run time to parse legitimate image file types
l_export() tries to be clearer in documentation about the limitations; l_export_valid_formats() tries to not rely on .withTclImg

From NEWS.md in the release

Install

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

install.packages("loon", 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("great-northern-diver/loon")

Development version from great-northern-diver/loon. 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-loon

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-loon

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

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