title: troubleshooting object 'tibble_update_attrs' not found in R
body: <p>I have been having troubles with R this morning, first reading in a .csv file, followed by trying to use GGPLOT2.  To make sure it wasn't my code, I went to <a href="http://www.sthda.com/english/wiki/ggplot2-barplots-quick-start-guide-r-software-and-data-visualization" rel="nofollow noreferrer">http://www.sthda.com/english/wiki/ggplot2-barplots-quick-start-guide-r-software-and-data-visualization</a> and grabbed the following code:</p>
  
  <pre><code>df &lt;- data.frame(dose=c("D0.5", "D1", "D2"),
                   len=c(4.2, 10, 29.5))
  head(df)
  
  
  library(ggplot2)
  # Basic barplot
  p&lt;-ggplot(data=df, aes(x=dose, y=len)) +
    geom_bar(stat="identity")
  p
  
  # Horizontal bar plot
  p + coord_flip()
  </code></pre>
  
  <p>I can create the dataframe, but then get this error upon running the Basic Barplot code:
  Error in update_tibble_attrs(x, ...) : 
    object 'tibble_update_attrs' not found</p>
  
  <p>I updated packages, reinstalled GGPLOT2, restarted R-Studio and computer to no avail.  Earlier today I was getting similar errors about tibbles when trying to build dataframes from scratch, and reading in .csv files.</p>
  
  <p>I have Googled but have not found a relevant answer (or at least one that looks relevant).</p>
  
  <p>How do I start troubleshooting this error?</p>
  
  <p>Thanks!</p>
