Below is an R chunk showing the structure.
data(iris) str(cars)
## 'data.frame': 50 obs. of 2 variables: ## $ speed: num 4 4 7 7 8 9 10 10 10 11 ... ## $ dist : num 2 10 4 22 16 10 18 26 34 17 ...
Below is an R chunk showing a table.
Below is a table.
head(cars)
## speed dist ## 1 4 2 ## 2 4 10 ## 3 7 4 ## 4 7 22 ## 5 8 16 ## 6 9 10

plot(cars$speed,cars$dist)
