# The Problem

Copy this into the RStudio editor and then collapse the YAML in this gist to see the problen.  The problem is this:

1.) collapsing the beginning of the YAML leaves the last line plus the trailing `---`.
2.) collapsing the trailing `---` collapses the code chunk to follows.

Interestingly, the Github editor also has the same problem with the yaml collapsing incorrectly.
