Test new post via add-in menu

To write a new post (like this one) using blogdown in RStudio, just click “Addins” -> “New Post” near the top of the RStudio window.

Here’s some junk R code. In the chunk options, just set eval=FALSE.

plot(x)

I should get used to writing (R) markdown pretty quickly, after translating a few of my plot posts.

Just for fun, here’s a plot.

plot(x <- seq(-10,10,length.out=100), sin(x), type='l', xlab='x', ylab='sin(x)')

Syntax highlighting

At time of writing, I’m still having problems with syntax highlighting. Removing line numbers by taking pygmentsOptions = "linenos=table" out of the config.toml file doesn’t help because for some strange reason that removes the background on the displayed code chunks such that I can’t see light-colored text. Here’s an example of how more than one line of code apparently fixes the problem.

myfn <- function(a,b,c){
    return (a*b*c)
}

Embedding pictures

And here’s a picture, to test: Caption for the picture.

Maybe I can do it in a different size (200px):

knitr::include_graphics("/images/test-oc.jpg")

How about 400 px?

knitr::include_graphics("/images/test-oc.jpg")

How about 800?!

knitr::include_graphics("/images/test-oc.jpg")

Shortcodes

I can embed a Youtube video using shortcodes, like:

blogdown::shortcode('youtube', '2xkNJL4gJ9E')

…or a tweet…

blogdown::shortcode('tweet', '852205086956818432')
