Code and tables

Syntax highlighting

Here is a sample code chunk, just to show that syntax highlighting works as expected.

library(ggplot2)
     library(dplyr)
     
     not_null <- function (v) {
       if (!is.null(v)) return(paste(v, "not null"))
     }
     
     data(iris)
     tab <- iris %>%
       group_by(Species) %>%
       summarise(Sepal.Length = mean(Sepal.Length),
                 Sepal.Width  = mean(Sepal.Width),
                 Petal.Length = mean(Petal.Length),
                 Petal.Width  = mean(Petal.Length))

Verbatim

Here is the structure of the iris dataset.

str(iris)

'data.frame':   150 obs. of  5 variables:
      $ Sepal.Length: num  5.1 4.9 4.7 4.6 5 5.4 4.6 5 4.4 4.9 ...
      $ Sepal.Width : num  3.5 3 3.2 3.1 3.6 3.9 3.4 3.4 2.9 3.1 ...
      $ Petal.Length: num  1.4 1.4 1.3 1.5 1.4 1.7 1.4 1.5 1.4 1.5 ...
      $ Petal.Width : num  0.2 0.2 0.2 0.2 0.2 0.4 0.3 0.2 0.2 0.1 ...
      $ Species     : Factor w/ 3 levels "setosa","versicolor",..: 1 1 1 1 1 1 1 1 1 1 ...

Table

Here is a sample table output.

Species	Sepal.Length	Sepal.Width	Petal.Length	Petal.Width
setosa	5.006	3.428	1.462	1.462
versicolor	5.936	2.770	4.260	4.260
virginica	6.588	2.974	5.552	5.552

Here we display a crosstab displayed in several different ways with a “pills” interface. To do this, just pass your table() result to the pilltabs() function.

Here is an histogram.

And a wonderful scatterplot, with a caption.

And finally, an incredibly complex equation :

\[ y = \sqrt{\frac{1}{x}} \]
