I've added the following code chunk at the beginning of these slides because there appears to be some error with the R code that I couldn't figure out in less than a couple minutes.

```{r global_options, include=FALSE}
knitr::opts_chunk$set(eval = FALSE)
```

In order to see what's wrong with a particular Rmd, remove the chuck above and try to knit the document, or run make.

Getting and Cleaning Data

• XML lecture causes my machine to segfault

Exploratory Data Analysis

• ggplot2 Part 1: Data is missing (eno.csv, skin.csv, etc)
• ggplot2 Part 2: Same as above
• Principles: Missing data, tries to access a local directory

Practical Machine Learning

• Forecasting: xts is not behaving.

Statistical Inference

• tCIs: Where are x1 and x2 supposed to come from?

Regression Models

• rttm: The ggplot2 API has changed and I don't know what graph you were trying to make.
• Residual Variation: same as above
• Multivariable regression examples: same as above but wrt the GGally API.
• Inference in regression: xVals has no value

Video recording duties

• R Packages: Roger records new demo video building R package in RStudio
• R Markdown: Roger
• Shiny p 1: Brian
• Shiny p 2: Brian
• Shiny Gadgets: Brian
• swirl authoring: Sean
• Plotly: Brian
• Domino: Jeff
• Leaflet: Sean
• GoogleVis: ?

The makefile doesn't work out of the box for me and I think it might be an issue with what default packages are loaded when Rscript is called. Do you have leaflet loaded on startup? For some reason it can't find the leaflet package even though it is installed.
