roperators

Small, friendly operators and helpers that let your R code read the way you already think it.

Which would you rather write?

base R

roperators  ← cleaner

paste0(“Hi”, name, “, you have”, n)

f(“Hi {name}, you have {n}”)

c(1, NA, 3) == c(1, NA, 4)

c(1, NA, 3) %==% c(1, NA, 4)

isTRUE(all.equal(0.1 + 0.1 + 0.1, 0.3))

(0.1 + 0.1 + 0.1) %~=% 0.3

x[is.na(x)] <- 0

x %na<-% 0

ifelse(b == 0, NA, a / b)

a %/0% b

On the package site this is an interactive taste test — you pick the line you’d rather write, and it tells you if you’ve got good taste. →

All base R, zero dependencies — just operators and helpers that say what you mean. (Pronounced rop-er-ators, not r-operators.)

Installation

install.packages("roperators")                       # released, from CRAN
# remotes::install_github("BenWiseman/roperators")
install.packages("roperators", repos = c('https://benwiseman.r-universe.dev', 'https://cloud.r-project.org'))      # or the dev version

Find the right tool

On the package website this is an interactive finder — search by what you’re trying to do (“join two strings”, “missing values”, “read a file”…) and jump straight to the docs. The full reference lists everything.

A quick note on shared names: %+% is also ggplot2’s, and %like%-style matching is data.table’s. If you load those too, use the namespaced form (roperators::%+%) where it matters.
