R Markdown

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 http://rmarkdown.rstudio.com.

When you click the Knit 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:

library(ggplot2)
ggplot(data=mpg) + geom_point(mapping = aes(x=displ, y=hwy)) + facet_wrap(~class, nrow=2)

ggplot(data=mpg) + geom_point(mapping = aes(x=displ, y=hwy)) + facet_wrap(~drv, nrow=2)

ggplot(data=mpg) + geom_point(mapping = aes(x=displ, y=hwy)) + facet_wrap(drv ~ cyl)

ggplot(data=mpg) + geom_smooth(mapping = aes(x=displ, y=hwy))
## `geom_smooth()` using method = 'loess' and formula = 'y ~ x'

ggplot(data=mpg) + geom_smooth(mapping = aes(x=displ, y=hwy, linetype = drv)) 
## `geom_smooth()` using method = 'loess' and formula = 'y ~ x'

ggplot(data=mpg) + geom_smooth(mapping = aes(x=displ, y=hwy, linetype = factor(mpg$cyl)))
## Warning: Use of `mpg$cyl` is discouraged.
## ℹ Use `cyl` instead.
## `geom_smooth()` using method = 'loess' and formula = 'y ~ x'

ggplot(data = mpg, mapping = aes(x = displ, y= hwy)) + geom_point() + geom_smooth()
## `geom_smooth()` using method = 'loess' and formula = 'y ~ x'

library(dplyr)
## 
## Attaching package: 'dplyr'
## 
## The following objects are masked from 'package:stats':
## 
##     filter, lag
## 
## The following objects are masked from 'package:base':
## 
##     intersect, setdiff, setequal, union
ggplot(data=mpg, mapping=aes(x=displ, y=hwy)) + geom_point(mapping=aes(color=class)) + geom_smooth(data=filter(mpg, class == "subcompact"))
## `geom_smooth()` using method = 'loess' and formula = 'y ~ x'

ggplot(data=mpg, mapping=aes(x=displ, y=hwy)) + geom_point(mapping=aes(color=class)) + geom_smooth(data=filter(mpg, class == "subcompact"), se=FALSE)
## `geom_smooth()` using method = 'loess' and formula = 'y ~ x'

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
