?是否有可能以及如何在带有 kable 的 knitr/Sweave 报告中使用
kable
数学表达式? In the example below, $x^2$
is rendered "as is".在下面的示例中,
$x^2$
“按原样”呈现。
With xtable
, for the example below, I would use the option sanitize.colnames.function = function(x) x
of print.xtable
.对于
xtable
,对于下面的示例,我将使用选项sanitize.colnames.function = function(x) x
of print.xtable
。 Is there such an option for kable
? kable
有这样的选择吗?
\documentclass{article}
\usepackage{booktabs}
\begin{document}
<<>>=
library(knitr)
dat <- mtcars[1:5,1:5]
options(knitr.table.format = "latex")
@
<<results='asis'>>=
names(dat)[1] <- "$x^2$"
kable(dat, booktabs=TRUE, caption="My table")
@
\end{document}
是的,使用选项escape=FALSE
:
kable(dat, booktabs = TRUE, caption = "My table", escape = FALSE)
Yes, use this:是的,使用这个:
names(dat)[1] <- "$x^{2}$"
this might also help you sometime:这有时也可能对您有所帮助:
names(df) <- c("$\\lambda_1$", "$\\lambda_2$","$\\lambda_3$" )
the result is the same of:结果与以下相同:
names(df) <- c("$λ_{1}$", "$λ_{2}$", "$λ_{3}$")
