Overview

About

Maintained by Antoine FabriCRAN page ↗GitHub ↗Website ↗Issues ↗

Visualize as flow diagrams the logic of functions, expressions or scripts in a static way or when running a call, visualize the dependencies between functions or between modules in a shiny app, and more.

Changes in 0.2.0

The LICENSE was switched from GPL-3 to MIT
New function: flow_compare_runs() displays 2 calls on the same diagram, making it easy to observe their divergence
New function: flow_view_uses() displays functions that recursively call its input, basically it does the opposite of flow_view_deps()
New function: flow_view_source_calls() draws the dependencies between files sourcing each other.
flow_view_deps() gains an include_formals arg, TRUE by default, so it displays dependencies used in formals.
flow_view_deps() accepts a list of functions as input, to display a diagram that starts from several functions.
flow_view_deps()'s trim, promote, demote, trim arguments support regular expressions.

Show all changes in 0.2.0Hide the rest of the changes in 0.2.0

flow_view_doc() and flow_view_doc() were simplified to output only html since the md output was rarely used and brittle.
flow_debugonce() is deprecated, use flow_debug() and flow_undebug()
Diagram drawing functions now return by default a "flow_diagram" object, it contains the widget, the code and the data of the diagram and has a print() method that displays the diagram.

From NEWS.md in the release

Install

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

install.packages("flow", 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("moodymudskipper/flow")

Development version from moodymudskipper/flow. 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-flow

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-flow

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-flow

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.
