kable_as_image knitr/kableextra rmarkdown

Question

I am trying to use the function kable_as_image, which from my understanding will save the table as a image. My results though is not a table, dont know if I am doing something wrong as I cant find an example.

```{r}
kable_as_image(kable(head(iris)), filename = "~/Documents/.../.../pic")
```

Now I feel like kable_as_image is a somehow misleading name for the function. As explained in the doc, as least right now, it only works for latex tables, try kable_as_image(kable(..., format = "latex", booktabs = T), filename = "pic").
