# Materials
If you don't have it already, now might be a good time to install R and RStudio to get started.
- [Download R](http://cran.r-project.org/)
- [RStudio](http://www.rstudio.org/)
- We'll also want to install a few basic packages. This can be done on the fly later, but a few include `ggplot2`;`knitr`;`plyr`
# Installing R on Windows
<p align='center'><iframe src="http://www.screenr.com/embed/kzT8" width="650" height="396" frameborder="0"></iframe></p>
# Installation Tips
- Setting up R on Windows XP is straightforward. On Windows 7 or Vista you may need to run in administrator mode to install extensions.
- Standard R interface in Windows is pretty ugly, which is why we use RStudio!
# Next Install packages
First, watch this tutorial<br>
<p align='center'><iframe src="http://www.screenr.com/embed/Fps8" width="650" height="396" frameborder="0"></iframe></p>
# Install Packages
- Are you running RStudio in administrator mode on Windows Vista or Windows 7?
- If not, you need to be. Right click on RStudio and then click "Run as Administrator"
- If you are on a Mac or Windows XP you can disregard this
# Install Packages (2)
- Now, copy and paste the code below into the bottom left window in RStudio (the R terminal):
```{r, eval=FALSE,echo=TRUE,tidy=FALSE}
install_new<-function(mypkg){
if (mypkg %in% installed.packages()) cat("Package already installed")
else{cat("Package not found, so installing with dependencies... /n
Press CTRL C to abort.")
Sys.sleep(5)
install.packages(mypkg,repos="http://cran.wustl.edu/")
}
}
install_new('plyr')
install_new('lmtest')
install_new('ggplot2')
install_new('gridExtra')
install_new('stringr')
install_new('knitr')
install_new('quantreg')
install_new('zoo')
install_new('xtable')
install_new('lme4')
install_new('caret')
```
# How it Works
- I will present a mixture of concepts and examples that illustrate various features of R
- Periodically we will stop and do some exercises to practice what we have talked about
- You have been provided with the data used and all the code in the examples on the screen
- For each tutorial simply open the "Tutorial X.R" file associated with the tutorial number to get access to the R code associated with each slide
- We'll talk about how to load the data
- You can follow along as I move through the slides, or wait until we pause for an example and run the code
- Please hold questions until either the exercise period or the end of each tutorial due to the large size of the class!
# Housekeeping
- No food in the Training Center (drinks only with covered lids!)
- Feel free to get up at any time as necessary
- Let's make sure now everyone can launch R, RStudio, and has downloaded and can access the materials for the training
- Also, make sure you are set up with the wi-fi password!
# Have fun!
Let's get started!
