    Welcome to stackoverflow! Please read [this](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) and update your question. – ismirsehregal Sep 08 '20 at 13:25
  • did you *load* `ggfortify` as well as installing it? (You should probably add your "PS" to the body of your question rather than the title ...) – Ben Bolker Sep 08 '20 at 14:02

Try

  • installing the ggfortify package (via install.packages("ggfortify")) [you only need to do this once per computer/installation of R] and
  • loading it (via library("ggfortify"))

then retry your autoplot() command.

  • You are correct, I tried an example after posting my (incorrect) answer and deleted mine once I realized you were right. – jjack Sep 08 '20 at 14:07
