You have worked through the first three parts of the textbook, introducing you
to the basic tools and processes in R. This whole book is useful, but we cannot
cover the whole book. You can choose what you would like to explore from here
when the semester is over.
The remaining three parts of the book are Part IV Import, Part V Program, and
Part VI Communicate. We will sample a section or two from each part.
This week you can practice importing data from and exporting data to spreadsheets.
In the time before the marriage of data science and statistics, people collected,
analyzed, and shared data in spreadsheets. We still do, and there is a strong
case that Excel is probably the single most useful computer application ever
written.
You will still need to collect information from and present information to people
who have no experience in R. Excel is a great common denominator and it is hard
to find someone who is not at least comfortable opening and reading an Excel
spreadsheet.
Google Sheets grows in popularity due to the ease with which people can access
it "free of charge", but Excel still eclipses Google Sheets in power and
functionality.
Try a few exercises in Homework-13.R reading and writing files to and from Excel
and Google Sheets.
Assessment deadlines will be 11:59pm each Saturday.
All assessments are submitted to the Homework Folder inside your assigned
Google Drive folder.
There are no make-ups for missed assessments. Contact me before a deadline
if you have an issue meeting the deadline and we will find a mutually
agreeable solution.
