Course Description

R is a free, open source statistical package that is increasingly being used in many fields. While R is free, it is not cheap — meaning that mastering R requires some time investment. It is particularly helpful to have some guidance in the more complex applications of R.

Class Size: class size is limited to 16 people.

Bring: Laptop computer pre-loaded with software (see below)

Prerequisites: It is assumed that participants have a basic familiarity with R — this is NOT a course for beginners for R. For example, it will be assumed that you can read basic data using read.table() or read.csv() into a data frame; that you can compute basic statistics, e.g. using the mean() function, and have a basic understanding of plotting, e.g. using basic plot() command.

Course Content

1. Quick review of basic R

  • data frames, vs vectors vs. matrices. vs lists
  • selecting rows/columns of objects
  • more advanced functions, e.g. grep, recode,
  • dealing with dates and times

2. Basic model fitting

  • The basic ANOVA and regression models using the lm() function.
  • Multiple comparisons using the lsmeans package
  • Predictions; confidence intervals for the mean and prediction intervals

3. Basic Plotting

  • Basic plotting using Base R plot(), histogram(), strip.chart(), boxplot() functions
  • Saving these for use in your reports

4. Better graphing via ggplot – much better than Base R graphics

  • Basic qplot and ggplot commands
  • More advanced features of ggplot
  • Saving ggplot graphics

5. Improve your R output

  • making nicer tables and text output
  • generating nicer reports using R Markdown (but not using Sweave)

6. Functions – generalize your work

  • how to write functions
  • different data structures for input and output (e.g. data frames, lists, etc)
  • passing data among functions; scoping rules;
  • debugging your functions
  • sourcing and function management

7. Subgroup processing

  • the plyr package – processing for sub-groups of your data

8. Bootstraping/simulation studies

  • how to find standard errors for non-standard cases
