 ## Comments
-This submission fixes a bug in the get_elev_raster function.  The API key for mapzen had a typo.  This also required some changes to testing the package.  The package is now tested locally and via travis-ci.  The tests are skipped on CRAN.  
+This submission fixes a bug in the get_elev_raster function.  The API key for mapzen had a typo.  This also required some changes to testing the package.  The package is now tested locally and via travis-ci.  The tests are skipped on CRAN.  Additionally, this corrects a problem with vignettes on a prior submission.
