Overview

About

Maintained by Dominic JarkeyCRAN page ↗GitHub ↗

Functions to safely map from a vector of keys to a vector of values, determine properties of a given relation, or ensure a relation conforms to a given type, such as many-to-many, one-to-many, injective, surjective, or bijective. Permits default return values for use similar to a vectorised switch statement, as well as safely handling large vectors, NAs, and duplicate mappings.

Changes in 1.0.0

Features

relatable provides two easy-to-use, robust functions for mapping from

a vector of keys to a vector of values, as well as creating and applying

more sophisticated mappings, such as many-to-many, one-to-many, and

many-to-one relations. These are primarily designed with two goals in

mind:

1. Producing reusable code that is easier to write and read.

2. Ensuring relations conform to specified restrictions, for example

injectivity or surjectivity, and safely handle nonstandard mappings,

including unexpected inputs, NAs, heterogeneous lists containing

multiple variable types including other lists, and mappings between

vectors of uncertain or unequal lengths.

Functions

relate returns a vector *Y = F(X)* where *F* maps each element of

input vector X from its position in vector A to its corresponding

position in vector B. Can be applied as a vectorised key-value

dictionary with an optional default return value. Additional options

restrict mapping types so relation *F* must be a function, injective,

surjective, etc.

relation returns a reusable function *F* that performs the same

operation as relate. In addition to providing a reusable function, if

handle_duplicate_mappings = TRUE, relation checks for and eliminates

duplicate mappings that would be invalid inputs for relate. If

report_properties = TRUE, relation also prints the restrictions the

mapping from A to B conforms to.

Install

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

install.packages("relatable", 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("domjarkey/relatable")

Development version from domjarkey/relatable. 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-relatable

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-relatable

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-relatable

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.
