This page provides introductory information on the use of R in an introductory applied statistics class. In particular, it provides:
This is a package designed for introductory statistics students. It adds functionality to many R functions, in addition to streamlining output and implementing many STATA functions in R. The package grew out of a desire for students in the introductory biostatistics courses at the University of Washington to learn statistical analysis techniques using R. We believe that the output given by the package is more germane to the problems most introductory students will face than that in the base R functions, or in many other packages.

This site hosts the current version of the package, which is 0.0.1, in .tar.gz form for Mac or Linux and in .zip form for Windows. This version was updated on 1 September, 2015.
While package vignettes can be accessed using the
browseVignettes() function in R, we also provide the vignettes here. We have one for regression in
uwIntroStats, one for writing multiple-partial F-tests in regression, and one showing the various test cases that we have used in different documents.
We have written An Introduction to R, aimed at students who wish to gain an introduction to coding in R, reading data in to a session, and the various ways that data is stored.
For those who have previously used STATA, we offer a STATA-R translation document.
Last, we present a document outlining our philosophy and approach to analyzing a data set, along with examples and code, titled Notes re: FEV. We analyze the FEV dataset, hosted on this website under the datasets page. This analysis shows the typical process that Scott goes through in a quarter teaching Applied Biostatistics at the University of Washington.
All of the documents are presented again below. We also have some video tutorials on installing R and RStudio for Windows and Mac OS, using graphical user interfaces with R,
the R workspace and data frames, and an introductory video to the
