Hi all,

Does anyone know why the PR builder keeps failing on SparkR's CRAN checks?  I've seen this in a lot of unrelated PRs.  E.g.: https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/90065/console

Hossein spotted this line:
```
* checking CRAN incoming feasibility ...Error in .check_package_CRAN_incoming(pkgdir) : 
  dims [product 24] do not match the length of object [0]
```
and suggested that it could be CRAN flakiness.  I'm not familiar with CRAN, but do others have thoughts about how to fix this?

Thanks!
Joseph
