The new iOS version of R Instructor has been released! Enjoy the new interface built for iOS7 and the major under-the-hood stability and performance enhancements!

In addition to the core code being updated, I've added a section on qplots (from the ggplot2 package) and additional content to the base plot section. In the next update, I will include additional material on the ggplot2 package.

Additions to base plots section:

1. Add a grid 

2. Add and modify arrows

- change arrow head shape

- change arrow head length

- change arrow color

- change arrow line width

- change arrow line type

- change arrow head angle

3. New qplot section (requires ggplot2):

How to make qplots:

- Boxplot

- Histogram

- Density histogram

- Frequency polygon

- Line chart

- Path plot

- Scatter plot

- Conditional smoother

4. Modifications described for each of the qplots:

- add color, either specific color or according to a third variable

- add title or change title font size

- add facets

- adjust line widths and point sizes

- ... and a few other modifications specific to particular qplots.
