Using the r2d3 package, I can render a simple d3.js chart in RMarkdown using something like this:
barchart.js:
// !preview r2d3 data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20)
var barHeight = Math.floor(height / data.length);
svg
.selectAll("rect")
.data(data)
.enter()
.append("rect")
.attr("width", function (d) {
return d * width;
})
.attr("height", barHeight)
.attr("y", function (d, i) {
return i * barHeight;
})
.attr("fill", "steelblue");
RMarkdown:
```{r out.width='100%', fig.height=4}
library(r2d3)
r2d3(data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20), script = "barchart.js")
```
But, let's say I wanted to draw the same chart, side-by-side (i.e. two charts next to one another in RMarkdown). Is there a way to do this? Doing this using simple RMarkdown is easy since you can save plots and then arrange in a grid; I don't see a way to do this in r2d3 since it doesn't save each plot as an object which you can arrange in a grid? Thank you.

I guess there are multiple ways of doing it. One option is using the Bootstrap Columns implemented in the crosstalk
package:
library(r2d3)
library(crosstalk)
crosstalk::bscols(
widths = c(6, 6),
r2d3(data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20), script = "barchart.js",
width = 300, height = 200),
r2d3(data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20), script = "barchart.js",
width = 300, height = 200)
)
On a side note - bscols is pretty useful to arrange any interactive html-widgets as well, and can solve most situations, where the "normal" Rmd output cannot be easily arranged.
