rbundler build error: "cannot open file 'startup.Rs': No such file or directory"

Question

I'm running into an issue when building the following package: https://github.com/yoni/rbundler

My test attempts to run rbundler's bundle command on a trivial package which has a single dependency. The test passes on my OSX machine, but fails on my x86_64-redhat-linux-gnu Jenkins server. Both machines are running R 2.15.1 with devtools 0.7.1, which includes this bug fix.

The full test output can be found in this gist.

Here's a short summary of error I'm seeing:

Error in file(filename, "r", encoding = encoding) : 
  cannot open the connection
Calls: local ... eval.parent -> eval -> eval -> eval -> eval -> source -> file
In addition: Warning message:
In file(filename, "r", encoding = encoding) :
  cannot open file 'startup.Rs': No such file or directory
Execution halted

---

The background for this is that I'm trying to build a dependency management system for R. The idea is that an R project should be able to run without using system-wide or user-wide libraries. Rather, the R project will have it's own library installed under it's root directory.

Answer 1

In my case this issue was caused by the environment variable R_TESTS that was set to startup.Rs

When you execute another R process from within your tests (in my case it was submitted via OGS qsub), the presence of this environment variable causes issues.
