英文:
How to get \% in paste0()?
问题
以下是翻译的部分：
我正在尝试使用R的paste0()生成一些Latex代码。为了打印百分号，我需要在它前面加一个单反斜杠，即结果应该类似于$95\%$。然而，paste0()不允许我添加一个单反斜杠。
paste0(95, "%")- 得到"95%"，这对Latex来说当然是无用的。paste0(95, "\%")- 会引发错误：Error: '\%' is an unrecognized escape in character string starting ""\%"paste0(95, "\\%")- 会输出两个反斜杠，即"95\\%"。但我只想要一个。
在这篇帖子中提到，使用\\%的paste0()会输出\%，但对我来说并非如此。有什么想法？
我正在使用R版本4.2.3（2023-03-15 ucrt）。
编辑：在控制台中使用cat()的解决方法有效，但在R Markdown/Quarto文档中不会显示，例如在使用以下内联代码时：
``` r cat("95\\%")
提前感谢！
英文:
I'm trying to generate some Latex code using R's paste0(). In order to print a percent sign, I need a single backslash in front of it, i.e., the result should be something like $95\%$. However, paste0() will not let me add a single backslash.
paste0(95, "%")- Gives"95%", which is of course useless for Latex.paste0(95, "\%")- Will throwError: '\%' is an unrecognized escape in character string starting ""\%"paste0(95, "\\%")- Will output BOTH backslashes, i.e.,"95\\%". But I only want one.
In this post, it says paste0() with \\% will output \%, but that is not the case for me. Any idea what's going on?
I'm using R version 4.2.3 (2023-03-15 ucrt).
EDIT: Solutions using cat() work in the console, but are not displayed in an R Markdown/Quarto document, e.g. when using the following inline code:
`r cat("95\\%")`
Thanks in advance!

I use glue
library(glue)
glue("95\\%")
95\%
We can also generate the strings dinamically:
value <- 95
glue("{value}\\%")
95\%
