在Jnit的Knitr中更改提示字符 [英] Change prompt character in knitr for JSS

问题描述

《统计软件杂志》 样式指南规定将R>用作提示字符.在Sweave中，可以通过以下方式获得:

The Journal of Statistical Software style guide prescripes use of R> as prompt character. In Sweave this can be obtained through:

options(prompt = "R> ", continue = "+  ", width = 70, useFancyQuotes = FALSE)

是否可以在knitr中设置prompt字符?似乎chunks$set中的prompt参数仅允许TRUE/FALSE.

Is it possible to set the prompt character in knitr as well? It seems like the prompt argument in chunks$set only allows for TRUE/FALSE.

推荐答案

在.Rnw文件中使用这种设置:

Use this kind of setup in the .Rnw file:

<<setup, include=FALSE, cache=FALSE>>=
library(knitr)
# set global chunk options
opts_chunk$set(prompt=TRUE)
options(replace.assign=TRUE, width=90, prompt="R> ")
@

注意，我在opts_chunk$set()中说了prompt=TRUE，然后在下一行的选项中指定了哪种提示类型.

Notice I say prompt=TRUE in the opts_chunk$set() and then specify what type of prompt in the options in the next line.
