In Rmarkdown I want to print two images from the web side by side. I'm trying this
```{r, echo=FALSE, out.width="33%", fig.align = "center", fig.cap="Examples of the FPTP bias: In Prairies (left) and Greater Toronto area (right). Source: www.fairvote.ca"}
knitr::include_graphics(
c("https://www.fairvote.ca/wp-content/uploads/2019/12/Western-alienation-website-FPTP-page.png", "https://www.fairvote.ca/wp-content/uploads/2019/12/Toronto-Peel-halton-2019-results-website-FPTP.jpg")
)
```
But instead I'm getting this - they are still printed one on top of the other:
Please advise. Note: I dont what to use cowplot or any other package.
