plu

Pluralize phrases in R

Overview

plu provides a simplified way to dynamically generate plain-language messages in R when we can’t know beforehand whether a message will be singular or plural.

Pluralizes English phrases based on the length of an associated vector. Contains helper functions to create natural language lists from vectors and to include the length of a vector in natural language.

Installation

You can install the stable release of plu from CRAN with:

install.packages("plu")

You can install the development version of plu from GitHub with:

# install.packages("remotes")
remotes::install_github("rossellhayes/plu")

Usage

formulas1 <- c(x %in% 1:3 ~ "low", x %in% 4:6 ~ "medium", "x %in% 7:9")
formulas2 <- c(x %in% 1:3 ~ "low", x %in% 4:6 ~ "medium", "x %in% 7:9", "high")
problems1 <- Filter(function(x) !rlang::is_formula(x), formulas1)
problems2 <- Filter(function(x) !rlang::is_formula(x), formulas2)

paste(
  "All arguments must be formulas.",
  plu::ral("Argument", problems1), 
  plu::stick(problems1),
  plu::ral("isn't a formula.", problems1)
)
#> [1] "All arguments must be formulas. Argument x %in% 7:9 isn't a formula."

paste(
  "All arguments must be formulas.",
  plu::ral("Argument", problems2), 
  plu::stick(problems2, usethis::ui_code),
  plu::ral("isn't a formula.", problems2)
)
#> [1] "All arguments must be formulas. Arguments `x %in% 7:9` and `high` aren't formulas."
