r - 使用 R 包 RefManageR 调整文本引用

Question

我正在尝试使用 R 包 RefManageR 管理引用书目，如下所示。

library(RefManageR)
file.name <- system.file("Bib", "RJC.bib", package="RefManageR")
bib <- ReadBib(file.name)

BibOptions(check.entries = FALSE, bib.style = "authoryear", max.names = 1,
           style = "citation", bibpunct = c("(",")","(",")",";",","))

Cite(bib, c("jennings2013bayesian", "ritchie2012novel"))
[1] "(Jennings, et al., 2013; Ritchie, et al., 2012)"

如何调整引文中的标点符号以获得以下所需的引文(et al 之前没有逗号)？

[1] "(Jennings et al., 2013; Ritchie et al., 2012)"

bibpunct 参数似乎没有可用的选项。

Answer 1

你可以像这样使用一个简单的正则表达式:

, (?=et al\.)
# match a comma, only when it is followed by et al.

这需要用一个空格代替，参见a demo on regex101.com .

在 R 中:

ref <- c("(Jennings, et al., 2013; Ritchie, et al., 2012)")
(ref <- gsub(", (?=et al\\.)", " ", ref, perl=TRUE))

这产生

[1] "(Jennings et al., 2013; Ritchie et al., 2012)"
