#Configuring RStudio Environement

Required packages and libraries:

options(repos = list(CRAN="http://cran.rstudio.com/"))
install.packages("dplyr")
## package 'dplyr' successfully unpacked and MD5 sums checked
## 
## The downloaded binary packages are in
##  C:\Users\Admin\AppData\Local\Temp\Rtmp6RSDe9\downloaded_packages
library(dplyr)
install.packages("tidyverse")
## package 'tidyverse' successfully unpacked and MD5 sums checked
## 
## The downloaded binary packages are in
##  C:\Users\Admin\AppData\Local\Temp\Rtmp6RSDe9\downloaded_packages
library(ggplot2)
library(data.table)

The following function will allow us pull data from Velocity:

PullVelocityData <- function(endpoint.url){
  raw.results <- readLines(endpoint.url)
  to.return <- data.table(jsonlite::fromJSON(raw.results))
  setnames(to.return, tolower(names(to.return)))
  return(to.return)
}

0.1 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

0.2 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.
