Released September 25, 2013

• New density plot type plot(l, type='density').
• xtable function to create LaTeX and HTML tables.
• Added several parameters related to centering bar plots. Can now include the center level and split across zero, or specify which level, or between which levels, centering occurs.
• Plot a histogram of responses (n) alongside the barplot.
• Summary function now includes neutral column. Values will be NA if no level is the center.
• If there is a neutral category in the bar plot it will be labeled with its percentage.
• Added parameter to wrap text in plots for long item names.

• Added group.order to reorder how groups are plotted. This also works for items in non-grouped items.
• Added parameters to turn off percent labels for low, high, and netural separately.
• Added a check to ensure all factors have the same number of levels.
• Items (i.e columns) that are not a factor will be converted to a factor using as.factor.
• Added reverse.levels function to reverse code factors. Useful when you wish to plot bars in reverse order (left-to-right).
• Two new demos, RecodeFactors and UnusedLevels show how to deal with common data issues before using the likert function.
• Added plot.percents parameter to label each category.
• Other bug fixes.
