create-r-package
About
This Claude Skill scaffolds a complete R package structure from scratch, following usethis conventions and tidyverse style. It generates essential files like DESCRIPTION, NAMESPACE, and setup for testing (testthat), documentation (roxygen2), dependency management (renv), and CI/CD (GitHub Actions). Use it when starting a new package, converting loose scripts into a structured package, or creating a skeleton for collaborative development.

建 R 包
搭全配之 R 包,以新具與最佳之法。
用時
- 由無而建 R 包
- 將散 R 本轉為包
- 為協作開發搭包骨
入
- 必要:包名(小寫,唯
.為特字) - 必要:包志之一行述
- 可選:許可類(默 MIT)
- 可選:作者信息(名、電郵、ORCID)
- 可選:是否起 renv(默為)
法
第一步:建包骨
usethis::create_package("packagename")
setwd("packagename")
得: 目錄建,含 DESCRIPTION、NAMESPACE、R/、man/ 子目錄。
敗則: 確 usethis 已裝(install.packages("usethis"))。察目錄未存。
第二步:設 DESCRIPTION
編 DESCRIPTION 含精元資料:
Package: packagename
Title: What the Package Does (Title Case)
Version: 0.1.0
Authors@R:
person("First", "Last", , "[email protected]", role = c("aut", "cre"),
comment = c(ORCID = "0000-0000-0000-0000"))
Description: One paragraph describing what the package does. Must be more
than one sentence. Avoid starting with "This package".
License: MIT + file LICENSE
Encoding: UTF-8
Roxygen: list(markdown = TRUE)
RoxygenNote: 7.3.2
URL: https://github.com/username/packagename
BugReports: https://github.com/username/packagename/issues
得: 合法 DESCRIPTION 過 R CMD check 無元資料警。
敗則: 若 R CMD check 警 DESCRIPTION 域,驗 Title 為題式大小寫、Description 逾一句、Authors@R 用合法 person() 語法。
第三步:設基建
usethis::use_mit_license()
usethis::use_readme_md()
usethis::use_news_md()
usethis::use_testthat(edition = 3)
usethis::use_git()
usethis::use_github_action("check-standard")
得: LICENSE、README.md、NEWS.md、tests/ 目錄、.git/ 已起、.github/workflows/ 已建。
敗則: 若某 usethis::use_*() 敗,裝缺依而重運。若 .git/ 已存,use_git() 略起。
第四步:建開發之配
建 .Rprofile:
if (file.exists("renv/activate.R")) {
source("renv/activate.R")
}
if (requireNamespace("mcptools", quietly = TRUE)) {
mcptools::mcp_session()
}
建 .Renviron.example:
RSTUDIO_PANDOC="C:/Program Files/RStudio/resources/app/bin/quarto/bin/tools"
# GITHUB_PAT=your_github_token_here
建 .Rbuildignore 項:
^\.Rprofile$
^\.Renviron$
^\.Renviron\.example$
^renv$
^renv\.lock$
^CLAUDE\.md$
^\.github$
^.*\.Rproj$
得: .Rprofile、.Renviron.example、.Rbuildignore 已建。開發文件排於建包外。
敗則: 若 .Rprofile 致起誤,察語法。確 requireNamespace() 守防可選包缺致敗。
第五步:起 renv
renv::init()
得: renv/ 目錄與 renv.lock 建。項目本地庫活。
敗則: 以 install.packages("renv") 裝之。若 renv 起時卡,察網或 options(timeout = 600)。
第六步:建包文件
建 R/packagename-package.R:
#' @keywords internal
"_PACKAGE"
## usethis namespace: start
## usethis namespace: end
NULL
得: R/packagename-package.R 存含 "_PACKAGE" 標。devtools::document() 生包級助。
敗則: 確文件名合 R/<packagename>-package.R。"_PACKAGE" 字串宜獨立表達,非函內。
第七步:建 CLAUDE.md
於項根建 CLAUDE.md,含項專 AI 助手之指。
得: CLAUDE.md 存於項根,含項專編慣、建命、構註。
敗則: 若疑含何,始以包名、一行述、常開發命(devtools::check()、devtools::test()),及任何非顯慣。
驗
-
devtools::check()返 0 誤 0 警 - 包構合期佈
-
.Rprofile加載無訛 -
renv::status()無問 - Git 庫已起含宜
.gitignore - GitHub Actions 工作流文件存
陷
- 包名衝:建名前以
available::available("packagename")察 CRAN - 缺 .Rbuildignore 項:開發文件(
.Rprofile、.Renviron、renv/)須排於建包外 - 忘 Encoding:DESCRIPTION 皆含
Encoding: UTF-8 - RoxygenNote 不合:DESCRIPTION 之版須合所裝 roxygen2
例
# Minimal creation
usethis::create_package("myanalysis")
# Full setup in one session
usethis::create_package("myanalysis")
usethis::use_mit_license()
usethis::use_testthat(edition = 3)
usethis::use_readme_md()
usethis::use_git()
usethis::use_github_action("check-standard")
renv::init()

sglang
MetaSGLang is a high-performance LLM serving framework that specializes in fast, structured generation for JSON, regex, and agentic workflows using its RadixAttention prefix caching. It delivers significantly faster inference, especially for tasks with repeated prefixes, making it ideal for complex, structured outputs and multi-turn conversations. Choose SGLang over alternatives like vLLM when you need constrained decoding or are building applications with extensive prefix sharing.
