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:

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00

Including Plots

##1.List
library(ggplot2)

ggplot(ggplot2::mpg) +
 aes(x = displ, y = hwy, colour = class) +
 geom_point(shape = "circle", size = 1.5) +
 scale_color_hue(direction = 1) +
 labs(title = "Relationship between engine size and fuel efficiency") +
 theme_minimal() +
 theme(plot.title = element_text(size = 12L, face = "italic"))

##2.List

library(ggplot2)

ggplot(ggplot2::mpg) +
 aes(x = displ, y = hwy) +
 geom_point(shape = "circle", size = 1.5, colour = "#879DC5") +
 theme_light() +
 facet_grid(vars(drv), vars(cyl))

##3.List
library(ggplot2)

ggplot(ggplot2::mpg) +
 aes(x = displ, y = hwy, colour = drv) +
 geom_point(shape = "circle", size = 1.5) +
 geom_smooth(span = 1L) +
 scale_color_brewer(palette = "Set2", direction = 1) +
 theme_minimal()
## `geom_smooth()` using method = 'loess' and formula 'y ~ x'

##4.List
library(ggplot2)

ggplot(ggplot2::diamonds) +
 aes(x = cut, fill = clarity) +
 geom_bar(position = "dodge") +
 scale_fill_hue(direction = 1) +
 theme_minimal()

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