roperators

CRAN version metacran downloads License: MIT R-CMD-check

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")      # 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.

At a glance

You want… Reach for
String concat / subtract %+% / %-%
String repeat / count %s*% / %s/%
In-place maths %+=% %-=% %*=% %/=% %^=%
Fill NAs / regex edit in place %na<-% / %regex=% / %regex<-%
NA-aware (in)equality %==% %>=% %<=%
Floating-point equality %~=% %>~% %<~%
Strict (value + class) equality %===%
Between (excl / incl) %><% / %>=<%

String interpolation f()
Inline error fallback %else%
Safe divide / tolerance %/0% / %+-%
Fuzzy string match %~%

Next steps

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.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
