Stat 505 Assignment 0.5

1. About Desire to Learn (D2L) If you've never used it, you can skip to (2). But if you used Blackboard or Moodle, it's a similar course management system.
   1. Do you prefer D2L as a means for me to communicate with the class? (I expect this to be infrequent, but will sometimes need to clarify a HW question or fix an error. The alternative is for me to use this email in a class list of emails.)

   2. Would you like me to post grades in D2L?

   3. Would you use a chat group in D2L?

2. On what computer will you be doing your homework? (Needs a word processor and R). Expected answers: my own laptop/desktop, Student lab computers in Reid/Roberts, my office computer, math dept machines, etc.
   1. Install R from CRAN. if it's not already there.
   2. Install RStudio from Rstudio.org if it's not already there.
3. Startup Rstudio session
   1. From the R help menu click "About R". What version of R are you using?

   2. Type help(boxplot) in the R editor. Near the bottom of the help page you should see this line

       ## Using 'at = ' and adding boxplots -- example idea by Roger Bivand --
