The following materials have been developed by Linda Brant Collins at the University of Chicago.  The materials require the same username and password.

• R handouts for Investigations (.pdf files and .tex files)
• R scripts for class demonstrations of Investigations
• Custom R functions written for simulations and other special class demonstrations
• Data files ready to load into R using R code in the form
   > mydata = read.table(filename="mydata.txt", header=TRUE)
• They can also be copied and pasted from the text files page
  
• Additional notes useful for teachers demonstrating Investigations in front of large classes can be found in the Classprep.pdf file.  

The following materials make use of the R commander

• Investigation 1.7.1
• Investigations 2.1.2 and 2.1.3
