knitr 的子图或子标题? [英] Subfigures or Subcaptions with knitr?

问题描述

是否可以使用 knitr 生成子图(带有关联的子标题)?这是一个最小的工作示例:

Is it possible to produce subfigures (with associated subcaptions) using knitr? Here is a minimal working example:

documentclass{article}

egin{document}

<<echo = FALSE, fig.cap = c("Some numbers.", "Some more numbers."), out.width = "0.5\textwidth", fig.align = "center">>=

plot(1:10)
plot(30:100)

@

end{document}

这会产生两个标记为图 1 和图 2 的图，并带有定义的标题(分别).但我希望它们被标记为图 1a"和图 1b"，就像您可以使用 subcaption LaTeX 包一样.

This results in two figures labelled Figure 1 and Figure 2 with captions as defined (respectively). But I want them to be labelled "Figure 1a" and "Figure 1b", as you can do with the subcaption LaTeX package.

我知道有一个 knitr 选项fig.env"，但这并不能解决它(至少不使用，例如，fig.env = 'subfigure'").这里有一篇关于 Sweave 的类似帖子，但解决方案是不优雅的 hack:http://texblog.org/2011/12/01/sweave-subfig-controlling-figure-size-and-placement/

I know there is a knitr options "fig.env", but this doesn't solve it (at least not using, for example, "fig.env = 'subfigure'"). There is a similar post here regarding Sweave, but the solution is an inelegant hack: http://texblog.org/2011/12/01/sweave-subfig-controlling-figure-size-and-placement/

推荐答案

knitr (>= v1.5) 支持子图.您可以使用块选项 fig.subcap.这是一个最小的例子.

knitr (>= v1.5) supports subfigures. You can use the chunk option fig.subcap. Here is a minimal example.

documentclass{article}
usepackage{subfig}
egin{document}

<<fig-sub, fig.cap='two plots', fig.subcap=c('one plot', 'the other one'), out.width='.49\linewidth'>>=
plot(1:10)
plot(rnorm(10), pch=19)
@

end{document}
