rpkgkit

The goal of rpkgkit is to provide useful functions for R package development.

Installation

From CRAN:

install.packages("rpkgkit")

From github:

if (!requireNamespace("pak")) {
  install.packages(
    "pak",
    repos = sprintf(
      "https://r-lib.github.io/p/pak/stable/%s/%s/%s",
      .Platform$pkgType,
      R.Version()$os,
      R.Version()$arch
    )
  )
}
pak::pak("Exceret/rpkgkit")

Features

All functions can detect active file contexts in RStudio and Positron, so generally file path can be omitted.

Available Standalone Scripts

Use usethis::use_standalone("WangLabCSU/rpkgkit", "<name>") to import:

args_to_func.R: matching arguments to function calls:

f1 <- function(a, b) a + b
f2 <- function(x, y, ...) x * y
f3 <- function(p, q) p - q

args <- list(a = 1, b = 2)

# Strict matching (default): returns f1 only
match_func_to_args(args, f1, f2, f3)

args <- list(a = 1, b = 2, x = 3, y = 4)
foo <- function(x , y = 1){x + y}
filter_args_for_func(args, foo) # Keeps arguments for foo
# $x
# [1] 3

# $y
# [1] 4

caller_cli.R: show where the cli function is called from

decorated <- add_caller_to_cli(cli::cli_alert_info)
foo1 <- \() {
  print("I' m in foo1")
  decorated("<- where is this called from?")
}
foo2 <- \() {
  print("I' m in foo2")
  foo1()
}
bar <- function() {
  print("I' m in bar")
  foo2()
}
bar()
# [1] "I' m in bar"
# [1] "I' m in foo2"
# [1] "I' m in foo1"
# ℹ [foo1()]: <- where is this called from?

colorful_cli.R: Easier color calling in one cli function

color_cli <- create_colorful_cli_env()
color_cli$cli_alert_danger("{.red This is a red message}")
color_cli$cli_alert_info("{.blue This is a blue message}")
color_cli$cli_alert_info("{.orange This is an orange message}")
# cyan, green, magenta, yellow, purple, etc

color_cli2 <- create_colorful_cli_env(cli_theme = generate_color_theme()) # more color but slower
color_cli2$cli_alert_success(
  "{.violetred3 R}{.orange a}{.yellow i}{.green n}{.cyan b}{.blue o}{.purple w}"
)

match_arg.R: partial matching of arguments to function calls, like match.arg, rlang::arg_match
ts_cli.R: timestamp cli function

ts_cli <- create_ts_cli_env()
ts_cli$cli_alert_info("Hello, world!")
# ℹ [2026/05/30 22:45:42] Hello, world!

R Function Transformation

make_func_call_explicit() - Make function calls explicit by adding package prefixes
package_func_call_explicit() - Make function calls explicit by adding package prefixes in a package

This is a code snippet from dplyr

starwars |>
  mutate(name, bmi = mass / ((height / 100)^2)) |>
  select(name:mass, bmi)

make_func_call_explicit("path_to_file", use_packages = "dplyr")

It will be converted to

starwars |>
  dplyr::mutate(name, bmi = mass / ((height / 100)^2)) |>
  dplyr::select(name:mass, bmi)

detect_lost_glue_brace() - Find all glue calls that are missing a closing brace in a file. Supports both glue and cli expressions.
package_lost_glue_brace() - Find all glue calls that are missing a closing brace in a package. Supports both glue and cli expressions.

# foo.R
name <- "world"
msg <- glue::glue("Hello, {name!")

library(cli)
warning <- ""
bar <- cli::col_red(cli::cli_alert_warning(
  "{.field warning}}: This string is missing {.val 1} brace{?s}"
))

detect_lost_glue_brace()

# msg <- glue::glue("Hello, {name!")
#                           ^^^^^^ 

#   "{.field warning}}: This string is missing {.val 1} brace{?s}"
#    ^^^^^^^^^^^^^^^^^ 
# ✖ Found 2 lines with mismatched braces: 3 and 8

make_func_arg_explicit() - Make function arguments are passed with explicit parameter names
package_func_arg_explicit() - Make function arguments are passed with explicit parameter names in a package

tf <- tempfile(fileext = ".R")
writeLines("vapply(1:9, function(x) x*2, numeric(1))", tf)
make_func_arg_explicit(tf)
# ✔ Made function arguments explicit in /tmp/RtmpOr1Iz0/file15b76c2120b264.R

cat(readLines(tf), sep = "\n")
# vapply(X = 1:9, FUN = function(x) x * 2, FUN.VALUE = numeric(length = 1))

rename_func() - Rename functions in a file with specific style

tf <- tempfile(fileext = ".R")
writeLines("this_is_a_function <- function(){message('Hello, world')}", tf)

rename_func(
  tf,
  style = "camelCase"
)
# ✔ Renamed 1 function to "camelCase" style in /tmp/RtmpOr1Iz0/file15b76c8de7e51.R

cat(readLines(tf), sep = "\n")
# thisIsAFunction <- function(){message('Hello, world')}

detect_print_and_cat() - Detect print() and cat() calls in a file
package_print_and_cat() - Detect print() and cat() calls in a package

print() and cat() are not allowed due to CRAN policy, so we need to fix them with message()

tf <- tempfile(fileext = ".R")
writeLines("print('Hello, world')", tf)
detect_print_and_cat(tf)
# print('Hello, world')
# ^^^^^^
# ✖ Found 1 unsupported call on line 
# 1.
detect_print_and_cat(tf, fix = TRUE)
cat(readLines(tf), sep = "\n")
# message('Hello, world')

convert_func_syntax() - Convert function syntax between function() and \()

f <- tempfile(fileext = ".R")
writeLines("f <- function(x) x^2", f)
convert_func_syntax(f)
# ✔ Converted function definitions in /tmp/Rtmp9ftJDS/file2a5a1320c9342e.R to "to_lambda"
message(readLines(f), sep = "\n")
# f <- \(x) x^2

convert_func_syntax(f, "to_explicit")
# ✔ Converted function definitions in /tmp/Rtmp9ftJDS/file2a5a1320c9342e.R to "to_explicit"
message(readLines(f), sep = "\n")
# f <- function(x) x^2

R Package Maintenance

use_zzz() - Create {pkgname}-package.R file in R/ folder, with .onLoad, .onAttach, %||% and package description. Similar to usethis::use_package_doc() but more powerful.

# * E.g., use it in rpkgkit dev environment
use_zzz()

check_pkgdown_reference() - Check if all exported function are referenced in _pkgdown.yml

check_pkgdown_reference()
# ✖ 9 exported functions missing from pkgdown reference:

use_vendor() - Reference a permissively-licensed R package from GitHub for inclusion in your own R package. Make it easy to import github R package under CRAN policy.

License, copyright and declaration are automatically generated in DESCRIPTION, R/vendor-*.R and inst/vendor/.
