This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see . When you click the **Knit** *knitr* button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this: # Header ## Subheader ### Subsubheader - List item 1 - List item 2 - Sublist item 1 - Sublist item 2 - List item 3 1. List item 1 2. List item 2 3. List item 3 ```{r} library(knitr) kable(summary(cars)) ``` You can also embed plots, for example: ```{r, echo=FALSE} plot(cars) ``` The mean of distance is `r mean(cars$dist)`. The mean speed is `r mean(cars$speed)`. ```{r} library(dplyr) cars <- filter(cars, dist < 100) ``` The mean of distance is `r mean(cars$dist)`. The mean speed is `r mean(cars$speed)`. You need to load the dplyr package using `library(dplyr)`.
