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  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

plot(pressure)

library(ggplot2)
## Warning: package 'ggplot2' was built under R version 3.3.3

# Vis 1
vis_1 <- ggplot(mpg)
vis_1 + geom_bar(aes(class, fill= trans)) + scale_fill_discrete(name = 'Transmission')

# Vis 2
vis_2 <- ggplot(mpg)
vis_2 + geom_boxplot(aes(manufacturer, hwy)) + theme_classic() + coord_flip() + labs(y = "Highway Fuel Efficiency (mile/gallon)", x= "Vehicle Manufacturer")

# Vis 3
ggplot(diamonds) + geom_density(aes(price, fill= cut, color= cut), alpha= 0.2, size= 0.2) + labs(title="Diamond Price Density", x= "Diamond Price(USD)", y= "Density") + theme_classic()

# Vis 4
ggplot(iris, aes(Sepal.Length, Petal.Length)) + geom_point()+ geom_smooth(method= lm)+ theme_classic()+ theme(panel.grid.major = element_line(size= 1), panel.grid.minor = element_line(size=0.5)) + labs(title= "Relationship between Petal and Sepal Length", x= "Iris Sepal Length", y= "Iris Petal Length")

# Vis 5
ggplot(iris, aes(Sepal.Length, Petal.Length, color = Species)) + geom_point() + geom_smooth(method = lm, se = FALSE) + theme_classic() + theme(text = element_text(family = "serif"), axis.ticks = element_line(color = "black", size = 0.8), legend.position = "bottom", legend.title = element_text(face = "plain"), plot.title = element_text(size = 14, face = "plain")) + labs(title = "Relationship between Petal and Sepal Length", subtitle = "Species level comparison", x = "Iris Sepal Length", y = "Iris Petal Length")

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