Error with automated checking

I've just started getting the following result from devtools::check(), and I'm not even sure how to interpret it:

Setting env vars:
-- R CMD check -----------------------------------------------------------------
   Error: 4:2: unexpected symbol
   3:     suppressMessages(require(testthat))
   4: }.Last
   Execution halted

It nonetheless finishes immediately afterwards with:

Duration: 208ms

0 errors v | 0 warnings v | 0 notes v

R CMD check succeeded

Does anyone have advice for how to start tracking down the issue?

A few follow-up questions to help you troubleshoot the issue:

  1. Are you able to build the package with devtools::build()?
  2. What happens when you test the package with devtools::test()?
  3. What file contains the line suppressMessages(require(testthat))? You can search the entire package in RStudio with Edit->Find in Files... (Ctrl-Shift-F). Can you share the contents of that file?

Thanks for the help.

  1. Yes.
  2. It passes all tests with complete execution.
  3. No file in the package contains that line of code.

Perhaps it is in your project or user level level .Rprofile?


OK, even stranger, my user .Rprofile file in its entirety:

if (interactive()) {

There is no .Last.

OK, I have the cause and the solution:

When I ran use_devtools() and copied the text over to .Rprofile, the text terminated without a carriage return. The solution was to simply add said carriage return to the end of the file.
