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: Visualization 1:

library(ggplot2)

library(ggthemes)

## Warning: package 'ggthemes' was built under R version 3.2.5

ggplot(mpg, aes(class,fill=trans)) + geom_bar()+guides(fill=guide_legend(title="Transmission"))

Visualization 2:

library(ggplot2)
ggplot(mpg,aes(manufacturer,hwy))+geom_boxplot()+coord_flip()+
  labs(y="Highway Fuel Efficiency(miles/gallon) ",          
       x="Vehicle Manufacturer")+theme_classic()

Visualization 3:

library(ggplot2)
library("ggthemes")
ggplot(diamonds, aes(x=price,color=cut,fill=cut)) + geom_density(aes(fill=factor(cut)), alpha=0.2) +theme_economist() + scale_colour_economist() +labs(title="Diamond Price Density ",          x="Diamond Price(USD)",
         y="Density")

Visualization 4:

ggplot(iris, aes(x = Sepal.Length, y = Petal.Length)) +  geom_point(position = "jitter")+ geom_smooth(method = "lm")+theme_minimal() + labs(title="Relationship between Petal and Sepal Length",  x="Iris Sepal Length",
y="Iris Petal Length")

Visualization 5:

ggplot(iris, aes(x = Sepal.Length, y = Petal.Length, color = Species)) + geom_point()+geom_smooth(method ="lm",se = F) + theme_tufte() +
  labs(title="Relationship between Petal and Sepal Length",
       subtitle="Species level comparison",
       x="Iris Sepal Length",
y="Iris Petal Length")+theme(
legend.position = "bottom")
