关于
This skill formats academic citations in styles like APA and IEEE using CSL processors and R tools. It converts between styles, generates in-text citations and reference lists, and validates formatting. Use it when rendering Quarto/R Markdown documents, converting bibliographies, or setting up citation infrastructure for projects.

格引用
以 CSL(Citation Style Language)處理器與 R 具格諸學風之引用。此技含 BibTeX 條轉為正格 APA 7、Chicago、Vancouver、IEEE、自風之文內引與參考列。用 Pandoc citeproc、knitcitations 包、Quarto 原引擎以造可復製之文。
用時
- 渲附格引之 R Markdown 或 Quarto 文
- 轉參考自一引風至另一
- 自 .bib 生獨立參考列
- 驗文內引合某風
- 為多文項(書、論)設引基設
入
- 必要:.bib 檔(或 Pandoc 認之他參源)
- 必要:目引風(如
apa、chicago-author-date、ieee) - 可選:CSL 檔路(默:用 Pandoc 內建風)
- 可選:出格(
html、pdf、docx;默:自文推) - 可選:語特格之 locale(默
en-US)
法
第一步:驗引基設
# Check Pandoc availability (required for citeproc)
pandoc_path <- Sys.which("pandoc")
if (!nzchar(pandoc_path)) {
pandoc_path <- Sys.getenv("RSTUDIO_PANDOC")
}
stopifnot("Pandoc not found" = nzchar(pandoc_path))
message(sprintf("Pandoc: %s", system2(pandoc_path, "--version", stdout = TRUE)[1]))
# Check for citeproc support
citeproc_ok <- any(grepl("citeproc", system2(pandoc_path, "--list-extensions", stdout = TRUE)))
message(sprintf("Citeproc: %s", ifelse(citeproc_ok, "built-in", "external needed")))
得: Pandoc 版本 2.11+ 察附內建 citeproc 援。
敗則: 裝 Pandoc 或於 .Renviron 設 RSTUDIO_PANDOC 指 RStudio 所附 Pandoc。Quarto 亦自攜 Pandoc。
第二步:設文 YAML 供引
R Markdown:
---
title: "My Document"
bibliography: references.bib
csl: apa.csl
link-citations: true
output:
html_document:
pandoc_args: ["--citeproc"]
---
Quarto:
---
title: "My Document"
bibliography: references.bib
csl: apa.csl
link-citations: true
cite-method: citeproc
---
得: YAML 頭正引 .bib 與 CSL 風。
敗則: 若 CSL 檔不見,自 CSL 庫下(見三步)置於項目。
第三步:取 CSL 風檔
# Common CSL styles and their repository names
csl_styles <- list(
apa = "apa.csl",
chicago = "chicago-author-date.csl",
vancouver = "vancouver.csl",
ieee = "ieee.csl",
nature = "nature.csl",
harvard = "harvard-cite-them-right.csl",
mla = "modern-language-association.csl"
)
download_csl <- function(style, dest_dir = ".") {
base_url <- "https://raw.githubusercontent.com/citation-style-language/styles/master"
filename <- csl_styles[[style]]
if (is.null(filename)) stop(sprintf("Unknown style: %s", style))
dest <- file.path(dest_dir, filename)
utils::download.file(
url = sprintf("%s/%s", base_url, filename),
destfile = dest, quiet = TRUE
)
message(sprintf("Downloaded %s to %s", filename, dest))
dest
}
# Download APA 7 style
download_csl("apa")
得: CSL 檔下至項目。
敗則: 察網。CSL GitHub 庫含萬餘風。離線用則將所需 CSL 捆於項目。
第四步:書文內引
於文體用 Pandoc 引語:
<!-- Single citation -->
According to @Smith2020, the method improves accuracy.
<!-- Parenthetical citation -->
The method improves accuracy [@Smith2020].
<!-- Multiple citations -->
Several studies confirm this [@Smith2020; @Jones2021; @Lee2022].
<!-- Citation with page number -->
As noted by @Smith2020 [p. 42], the results are significant.
<!-- Suppress author name -->
The results are significant [-@Smith2020].
<!-- Citation with prefix -->
[see @Smith2020, pp. 42-45; also @Jones2021, ch. 3]
得: Pandoc/Quarto 渲此為目風之正格引(如 APA 之 (Smith, 2020)、Chicago 之 (Smith 2020))。
第五步:以 R 生獨立參考列
# Using RefManageR to print formatted references
library(RefManageR)
BibOptions(style = "text", bib.style = "authoryear", sorting = "nyt")
bib <- ReadBib("references.bib", check = FALSE)
# Print all entries in text format
print(bib)
# Format specific entries
print(bib[author = "Smith"])
# Generate markdown reference list programmatically
format_reference_list <- function(bib, style = "apa") {
BibOptions(style = "text", bib.style = "authoryear")
entries <- capture.output(print(bib))
entries <- entries[nzchar(trimws(entries))]
paste(sprintf("- %s", entries), collapse = "\n")
}
cat(format_reference_list(bib))
得: 格之參考列印於控台或捕為字向供後處。
第六步:轉引風
# Render the same document in different styles
styles <- c("apa", "chicago", "ieee")
for (style in styles) {
csl_file <- download_csl(style)
output_file <- sprintf("output_%s.html", style)
rmarkdown::render(
input = "document.Rmd",
output_file = output_file,
params = list(csl = csl_file),
quiet = TRUE
)
message(sprintf("Rendered %s with %s style", output_file, style))
}
Quarto:
quarto render document.qmd --metadata csl:apa.csl -o output_apa.html
quarto render document.qmd --metadata csl:ieee.csl -o output_ieee.html
得: 多出檔,同容各以異引風格。
敗則: 若渲敗,察文體諸引鍵於 .bib 存。缺鍵生警然或破格。
第七步:驗引格
# Check for undefined citations in rendered output
validate_citations <- function(rmd_file, bib_file) {
# Extract citation keys from document
doc_text <- readLines(rmd_file, warn = FALSE)
doc_keys <- unique(unlist(regmatches(
doc_text,
gregexpr("@([A-Za-z][A-Za-z0-9_:.#$%&+-?<>~/]*)", doc_text)
)))
doc_keys <- gsub("^@", "", doc_keys)
# Remove false positives (email-like patterns)
doc_keys <- doc_keys[!grepl("\\.", doc_keys)]
# Extract keys from .bib file
bib <- RefManageR::ReadBib(bib_file, check = FALSE)
bib_keys <- names(bib)
# Find mismatches
undefined <- setdiff(doc_keys, bib_keys)
unused <- setdiff(bib_keys, doc_keys)
list(
undefined = undefined,
unused = unused,
cited = intersect(doc_keys, bib_keys)
)
}
result <- validate_citations("document.Rmd", "references.bib")
if (length(result$undefined) > 0) {
warning(sprintf("Undefined citation keys: %s",
paste(result$undefined, collapse = ", ")))
}
if (length(result$unused) > 0) {
message(sprintf("Unused .bib entries: %s",
paste(result$unused, collapse = ", ")))
}
得: 未定鍵(引而不於 .bib)、未用條(於 .bib 而未引)、與有效引之報。
敗則: 郵址或含 @ 之碼或致誤肯。精正則或手審所標鍵。
驗
- 文渲無 Pandoc/citeproc 引警
- 文中諸
@key皆解於 .bib - 參列於文末現(或
div#refs) - 文內引合目風格
- 引序循風則(APA 字序、IEEE 編序)
- 文內引至參列之超鏈行(若
link-citations: true)
陷
- 缺 CSL 檔:若無 CSL 指,Pandoc 退至 Chicago author-date。恆明設
csl:以一 - 引鍵拼誤:拼誤鍵如
@Smtih2020默渲為字。以--verbose啟 Pandoc 警以捕 - locale 格異:APA 英中作者間用「and」,德用「und」。於 YAML 頭設
lang:以合 - nocite 供未引條:欲參列含文中未引條,於 YAML 加
nocite: '@*'(諸)或nocite: '@key1, @key2' - CSL 版失配:老 CSL 0.8 檔或不兼現 Pandoc。恆用官庫之 CSL 1.0+
- Quarto 對 R Markdown 異:Quarto 默
cite-method: citeproc;R Markdown 或需明pandoc_args: ["--citeproc"]
