HK - Data 607 - Tidyverse Recipe - Part2
Note: This is extension of Lin Li’s work on tidyverse recipe. Also I used head function to show the top rows rather than all rows to avoid ovewhelmed output Create an Example. Using one or more TidyVerse packages, and any dataset from fivethirtyeight.com or Kaggle, create a programming sample “vignette” that demonstrates how to use one or m...

Data 607 - Tidyverse recipe - Part1
Introduction The aim for this assignment is to create an example of tidyverse library and it is splitted into two parts: Create an Example. Using one or more TidyVerse packages, and any dataset from fivethirtyeight.com or Kaggle, create a programming sample “vignette” that demonstrates how to use one or more of the capabilities of the select...

Data 607 - Week 12
Introduction For this assignment, you should take information from a relational database and migrate it to a NoSQL database of your own choosing. For the relational database, you might use the flights database, the tb database, the “data skills” database your team created for Project 3, or another database of your own choosing or creation. Fo...

Data 605 - HW1
library("geometry") library("Morpho") library(rsconnect) Problem 1 You can think of vectors representing many dimensions of related information. For instance, Netflix might store all the ratings a user gives to movies in a vector. This is clearly a vector of very large dimensions (in the millions) and very sparse as the user might have rated o...
