Tidyverse - mpg dataset - "drv" column data missing

hyoon0805 · November 12, 2020, 7:31pm

Hi, I have installed and loaded tidyverse package and am working with the mpg dataset. I just noticed that the entire "drv" column data is missing. I have no clue why all the data is shown as "NA". I tried deleting the entire package and reinstalling it, but it didn't help much. Can anyone help me with the issue?

> head(mpg)
  manufacturer model displ year cyl      trans **drv** cty hwy fl   class
1         audi    a4   1.8 1999   4   auto(l5)  NA  18  29  p compact
2         audi    a4   1.8 1999   4 manual(m5)  NA  21  29  p compact
3         audi    a4   2.0 2008   4 manual(m6)  NA  20  31  p compact
4         audi    a4   2.0 2008   4   auto(av)  NA  21  30  p compact
5         audi    a4   2.8 1999   6   auto(l5)  NA  16  26  p compact
6         audi    a4   2.8 1999   6 manual(m5)  NA  18  26  p compact

Thank you

Did you highlight this manually?

Strange. We are on the same setup. I'm on RStudio 1.3.1073. There are a few packages attached via namespace where we differ. You might try update.packages() and then see if there are any other datasets where this occurs.

yes, I did add the asterisks. I was hoping to bold it but then seems like it didn't work under the code block!

below is the sessioninfo I got if this helps!

Thanks! I'll try updating other packages as well. It is strange indeed since it's just one column that I'm missing.
