Test script crashes

When I run the testing script in /cfu/software/test-s2dverification it raises a message telling that the check process was unsuccessful. When I run the check process manually I get the following warning:

Warning in dir.create(pkgoutdir, mode = "0755") : '/home/nmanubens/s2dverification/s2dverification.Rcheck' already exists

Before I always passed the test script even having a previous .Rcheck folder. The test should pass now too even if this folder exists.
