Using header of chunk to save plot

问题

So I've been searching for an answer for this, and haven't really found anything. I'm hoping there isn't anything like this already on the board so I don't waste anyone's time. In the recent upgrade of I'm assuming RStudio, a method I used to save plots went away. Below is an example chunk of what it looks like:

```{r dummy, dev=c('png', 'pdf'), fig.height=4, fig.width=6}

x = 1:10
y = 10:1

plot(x,y)
```

The code will still compile when I do this. However, when I knit my code in order to save the plots, it does not save the plots. Is there a way similar to this that is compatible with the updated RStudio/knitr? Thanks for the help!

回答1:

you can add the self_contained: no option in the html_document output front matter section at the top of your Rmd. but the images are embedded in the html so you dont really need the images folder – rawr

EDIT:

like so:

---
output:
  html_document:
    self_contained: no
    <other options>
---

res of knitr document...

this will generate a couple new directories and within the "figure-html" one, you can find the images.
