I\'m trying to run the following code in R, but I\'m getting an error.

I\'m not sure what part of the formula is incorrect. Any help would be greatly appreciated.

Answer 1

I got the error because of a clumsy typo:

This errors:

knitr::opts_chunk$seet(echo = FALSE)

Error: attempt to apply non-function

After correcting the typo, it works:

knitr::opts_chunk$set(echo = FALSE)
