his is our first practical Visual training in Rstudio. After you install R and R studio, please read instruction file attached. Your goal is to create 5 different charts from ggplot2 R library. If you

ITS 530: Quiz 2 sample report

Visualization with ggplot2 library

See below cheat-sheet on this library for quick reference

https://rstudio.com/wp-content/uploads/2015/05/ggplot2-cheatsheet.pdf

• First I am reading my csv dataset

• Str(data) showed me general information about my dataset

• My dataset has 1803 obs. of 27 variables:

• The second picture to show how many null values in my dataset

• I have many null variables

• Next I will start my ggplot2 visualization

• # This quiz we will look at ggplo2 library visualizations

• # Our examples are from the link http://r-statistics.co/Top50-Ggplot2-Visualizations-MasterList-R-Code.html

• Our first plot is called: Scatterplot. Screens below shows results of my code for two variables from my data. x=R_C_PCT_CLASSES_GT_50, y=IS_RANKED

• I basically want to study class size with University rank scale

• The chart basically is telling me that Universities with lower rank tend to have less of those large classes

• The second chart scatter plot with encoding

• Complete the above two charts based on your dataset and any 3 more charts from the http://r-statistics.co/Top50-Ggplot2-Visualizations-MasterList-R-Code.html (Important, the charts and your code should be based on your dataset).
