More text tools

subheadings

Unordered lists:

• first item

• second item

Ordered lists:

1.first

2.second

We can insert an image like this:

We can add citations¹

We can use math mode \(\alpha /beta\) and so on.

Finally, we can make a nice tables.

mpg_sm <- head(mpg)
kable(mpg_sm)

manufacturer	model	displ	year	cyl	trans	drv	cty	hwy	fl	class
audi	a4	1.8	1999	4	auto(l5)	f	18	29	p	compact
audi	a4	1.8	1999	4	manual(m5)	f	21	29	p	compact
audi	a4	2.0	2008	4	manual(m6)	f	20	31	p	compact
audi	a4	2.0	2008	4	auto(av)	f	21	30	p	compact

audi	a4	2.8	1999	6	manual(m5)	f	18	26	p	compact

    theme_set(theme_bw())  # pre-set the bw theme.
    g <- ggplot(mpg, aes(cty, hwy))
    g + geom_jitter(width = .5, size=1) +     labs(subtitle="mpg: city vs highway mileage", 
          y="hwy", 
           x="cty",
