在 Rmarkdown 中调整 highcharter 绘图尺寸

Question

I am using highcharter plots in Rmarkdown and I can't seem to adjust the height or the width (in RStudio). Any suggestions? Details below:

If I use the basic default code;

```{r}
library(highcharter)

cars %>%
  hchart(.,"scatter",hcaes(x=speed,y=dist))
```

I get this:

That doesn't change if I edit chunk options fig.height=4,fig.width=8 or if I change dimensions in the plot hc_chart(height=800,width=600) .

If I save the plot and print using a taglist, then it starts to become usable.

```{r}
h <- cars %>%
  hchart(.,"scatter",hcaes(x=speed,y=dist))

htmltools::tagList(list(h))
```

But, I still can't adjust dimensions using chunk options or using internal plot dimensions.

R version 3.4.3 (2017-11-30)

Answer 1

Use hc_size with height and width arguments:

{r}
h <- cars %>%
  hchart(.,"scatter",hcaes(x=speed,y=dist)) %>%
  hc_size(height=800,width=600)
h

Had the same problem and the comment from @jbkunst (kudos to them) to your question led me to this solution and it works - so I thought I'd post it as an answer.
