Data Visualization using R (Statistics Project Sample)

Data Visualiza+on Quan%ta%ve Assignment Op%on Preliminary steps: • Literature and materials: • Wickham & Grolemund (2017) • ggplot2 Cheatsheet • R Cheatsheet • Presenta%on slides for weeks 9 & 10 • If you have not yet installed the tidyverse package, do so by typing the following command into the RStudio console: • Load the tidyverse package into RStudio, which comes with ggplot2 pre-installed: • Download the ldt.RData file from OPAL and load in into your RStudio environment, using either the file manager or by typing the code below into the console :1 The file will be saved in your RStudio environment as ldt. If loading the dataset manually make sure to replace FILE/PATH with the loca%on of the file on your computer. 1 NB: If you’re a Windows user, don’t use backslashes as directory separators! Indicate the file loca%on using forward slashes (e.g., C:/FILE/PATH/ldt.RData instead of C:FILEPATHldt.RData) or double backslashes (C: FILE\PATH\ldt.RData). 1 Task 3 Consider the following dataset • marvel.csv: data on characters from the Marvel universe (NOTE: the dataset uses the semicolon ‘;’, not the comma, as separator!) Load the dataset into RStudio. Explore your chosen dataset visually. Try out a variety of plot types on a variety of different variables. Choose your two favorite (or what you feel to be the most informa%ve) plots. Make sure the plots have a meaningful %tle and the axes meaningful labels. Describe and interpret the plots in a few sentences. Paste the code for them as well as the resul%ng plots below. Tip To create a new variable condi%oned by another variable, you can use the mutate() func%on,2 e.g.: The above code creates a new variable called BMI for the starwars dataset, which is based on the exis%ng variables mass and height. The result (a copy of the dataset now containing the new variable) is assigned back to the starwars dataset variable to save it. Please note that the mutate() func%on is part of the tidyverse package. h^ps://dplyr.%dyverse.org/reference/mutate.html source..
