在Hmisc :: latex中转义LaTeX控件符号 [英] Escaping LaTeX control symbols in Hmisc::latex

问题描述

我在R中有一个数据框，不幸的是其中有包含美元符号的字符串.当包 Hmisc 中的函数latex()转换时将此数据帧保存到LaTeX表中后，美元符号就不会转义.这使LaTeX无法编译. Hmisc中是否有一种方法可以在格式化数据框中的值时转义美元符号?

I have a data frame in R which unfortunately has strings in it containing dollar signs. When the function latex() from the package Hmisc converts this data frame to a LaTeX table, the dollar signs are not escaped. This renders the LaTeX uncompilable. Is there a way within Hmisc to escape dollar signs when formatting values from a data frame?

此后，我也无法运行搜索并替换所有美元符号，因为Hmisc本身会为空单元格添加美元符号.

I can't run search and replace over all dollar signs afterwards either, because the Hmisc itself adds dollar signs for the empty cells.

最小示例:

> latex("test$test",file="")
# returns:
\begin{table}[!tbp]
% [...]
test$test\tabularnewline
% [...]
\end{table}

# should return:
\begin{table}[!tbp]
% [...]
test\$test\tabularnewline
% [...]
\end{table}

推荐答案

您可以在Hmisc中查看latexTranslate函数:

R> latexTranslate("3%")
[1] "3\\%"
