- Documentation fixes per CRAN request.
- likert.density.plot has been deprecated.
- Added likert_anchors dataset and vignette.
- Many fixed to be compatible with the latest version of ggplot2.
- Added digits parameter to plot for heatmaps.
- Now check to ensure grouping variable does not have any missing values.
- Print a warning if any variables are not factors.
- New Shiny app that allows for interactively manipulate Likert options.
- Fixed a bug where the labels were placed on the wrong side.
- Now require ggplot2 versions greater than 2.2.0.
- Fixed a bug where stacked bars were in the wrong order in grouped plots.
- Plotting options are now passed as a list. The likert.options returns the default set of plotting options.
- Fixed a bug where the neutral labels would be printed twice when there were an odd number of levels and plot.percents = TRUE.
- Fixed a bug where the results for a grouped analysis with missing levels may not be correct in the print function.
- Update for ggplot2 version 2.0
- Removed all use of the reshape package.
- Fixes issue 40 where the histogram bars may not match the likert bars.
- Fix to work with the latest version of the xtable package.
- Added ability to group items by factor.
- Converted all uses of reshape to reshape2.
- Other fixes to pass R CMD CHECK.
- Added colors parameter to plot.likert.bar to define custom colors for levels.
- Fixed bug where an unused factor level would not appear in the legend.
- Added initial support for conducting gap analysis. A demo, GapAnalysis has also been added.
- Removed dependency on a non-exported function in ggplot2.
- Can now create a likert object with a pre-summarized data frame.
- New Shiny app to demonstrate many of the features in the likert package. The shinyLikert() function will start the app.
- Fixed bug where text.color parameter was not being used.
- Fixed bug 16.
- Fixed bug where automatic conversion to factors would not work if there were missing levels in an item.
- Added text labels to the histogram (if include.histogram=TRUE) for the n.
- Fixed a bug where plot.likert(…, include.histogram=TRUE) would not work with a group and only one item (i.e. one column).
- Updates for newer version of R and Roxygen.
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.
- Changed the default colors.
- Added parameter to change legend title.
- Can now plot bar plot panels horizontally.
- Changed the center=TRUE as the default for bar plots to.
- Added panel.flip to flip the placement of grouping elements and items.
- Added legend.position parameter.
- Added panel.strip.color to change the background color for panel labels.
- 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.
