likert (version 1.3.5.1)

Analysis and Visualization Likert Items

Description

An approach to analyzing Likert response items, with an emphasis on visualizations. The stacked bar plot is the preferred method for presenting Likert results. Tabular results are also implemented along with density plots to assist researchers in determining whether Likert responses can be used quantitatively instead of qualitatively. See the likert(), summary.likert(), and plot.likert() functions to get started.

Functions in likert (1.3.5.1)

Adapted from ggExtra package which is no longer available. This is related to an experimental mlpsa plot that will combine the circular plot along with the two individual distributions.

Prints results table.

Results from an administration of the Math Anxiety Scale Survey.

Builds an object with options for plotting likert results.

Results from the Survey of Academic Self-Regulation (SASR).

Reverse the levels of a factor.

print.likert.bar.plot

Print method for likert.bar.plot. The primary purpose is to suppress the "Stacking not well defined when ymin != 0" warning printed by ggplot2 for bar plots that have negative bars (i.e. the centered plots).

The zero grob draws nothing and has zero size.
