flextable

David Gohel's package flextable is a wonderful addition to the R table-building ecosystem. flextable is the only solution I know for tables that are not over-padded and way too big.

Code

library(svglite)
library(htmltools)

x <- 1967:1977
y <- c(0.5,1.8,4.6,5.3,5.3,5.7,5.4,5,5.5,6,5)
s <- svgstring(height = 4, width = 6)
plot(y ~ x, axes=F, xlab="", ylab="", pch=16, type="b")
axis(1, at=x, label=x, tick=F, family="serif")
axis(2, at=seq(1,6,1), label=sprintf("$%s", seq(300,400,20)), tick=F, las=2, family="serif")
abline(h=6,lty=2)
abline(h=5,lty=2)
text(max(x), min(y)*2.5,"Per capita\nbudget expanditures\nin constant dollars", adj=1, 
     family="serif")
text(max(x), max(y)/1.08, labels="5%", family="serif")
dev.off()
