Use check() and get error about `*-Ex.R`

devtools

#1

I am learning to build a package and get error when I I run check()

E  checking examples (625ms)
   
   See
     ‘/private/var/folders/yt/307v0c_945z1rh043jsdx1lh0000gn/T/RtmpvZl8ug/add2md.Rcheck/00check.log’
   for details.
   
   Running examples in ‘add2md-Ex.R’ failed

But I cannot find it from the spotlight on Mac.

It seems there is a function not found in your example file add2md-Ex.R Can you check that example? It needs to be able to run without error.


#4

Hi @cderv, I cannot find this file.

57

And The hello.R file is under the folder R I can see.


#5

You only have access to your package. Try to run you examples in clean session to see if everything goes well. There is a devtools helper function for that.
We can't help you more from afar.
