title: Problems with R (likert) package
body: <p>I'm trying to produce an R plot with likert scale data using RStdudio v1.0.153. I get the following error:</p>
  
  <pre><code>Error in likert(think) :
  All items (columns) must have the same number of levels
  </code></pre>
  
  <p>Link to my data is at: <a href="https://docs.google.com/spreadsheets/d/1TYUr-_oX9eADZ6it1w_4CQJ_wITP6xISaJJHTad3JbA/edit?usp=sharing" rel="nofollow noreferrer">https://docs.google.com/spreadsheets/d/1TYUr-_oX9eADZ6it1w_4CQJ_wITP6xISaJJHTad3JbA/edit?usp=sharing</a></p>
  
  <p>Below is the R code I used:</p>
  
  <pre><code>&gt; library(psych)
  &gt; library(likert)
  
  &gt; myColor &lt;- c("red","orange", "light blue","light green", "lavender")
  &gt; levels = c("Strongly Disagree", "Disagree", "Neutral", "Agree", "Strongly Agree")
  
  &gt; think$A = factor(think$A, levels, ordered = TRUE)
  &gt; think$B = factor(think$B, levels, ordered = TRUE)
  &gt; think$C = factor(think$C, levels, ordered = TRUE)
  &gt; think$D = factor(think$D, levels, ordered = TRUE)
  &gt; think$E = factor(think$E, levels, ordered = TRUE)
  &gt; think$F = factor(think$F, levels, ordered = TRUE)
  
  &gt; results &lt;- likert(think)
  &gt; plot(results, col = myColor) #Have not used this yet because of the error above
  </code></pre>
