R-Studio Connect and Interaction
Setting up R-Studio
Time to set up our R-Studio to share interactive documents.

Viewing on the website.
- view with shiny.byui.edu
Example: library(DT) - DataTables
Make a new Rmd file that just has the following in it (including the default yaml).

Team Discussion
Case Study 8: It’s about time
Case Study 9: Interacting with time
Task 17: My investment is better than yours
Try: library(DT) - DataTables
Look at the DT: An R interface to the DataTables library website and find one or two modifications that you could make to your table output to move beyond the default.
- Work as a table and push one file to R-Studio connect.
- Make sure everyone at the table has the code saved on their computers.

Time Series Data
Are we using timetk?
Looks like the task doesn’t require it. I wanted you guys to see this package and understand the potential if you need it in the future - Link.
tibles, ts, xts, and zoos oh my!
Use the links on this page to try and describe what ts, xts, and zoo formats are in R?
We are not going to take the time to get into the weeds of xt, xts, zoo. Here are two locations where you can read till your heart is content - 1, and 2.
Really matrix formats
Q: Why is xts implemented as a matrix rather than a data frame?
xts uses a matrix rather than data.frame because: 1) xts is a subclass of zoo, and that’s how zoo objects are structured; and 2) matrix objects have much better performance than data.frames.
Why xts?
Q: Why should I use xts rather than zoo or another time-series package?
The main benefit of xts is its seamless compatibility with other packages using different time-series classes (timeSeries, zoo, .). In addition, xts allows the user to add custom attributes to any object. See the main xts vignette for more information.
