Yes this question, but NOTHING is fixing it. I've searched to the end of Google.
Here are instructions form instructor:
Download this RData file to your working directory. Then load the data into R with the following command:
That triggers the error in title
The first fix to pop up: I add the simple type="binary" but that doesn't work. Instead I get a new error:
Error in install.packages : file ‘~/Downloads/skew.RData’ is not a macOS binary package
A few more answers said binary="TRUE"
That doesn't work.
I try some of the other fixes online here and nothing is working.
Yes devtools is installed but it seems that half of the 'answers' say you don't need it.
