shortestPath: Error in file.info(x) : invalid filename argument

I believe this is specific to something strange happening in RStudio, as the problem cannot be reproduced in the command line. The shortestPath function completes successfully but this message is inexplicably displayed as an error.

Hi Nicole,

I also see the same behavior in all three environments commandline (getPaths also indicates the same error), RStudio console/script, R Console. Here is link to code gist/github:
rscript code

Here is my commandline output (I labelled the output in my Rscript code output for convenience):

C:\sandbox\r\rcode_commandline>rscript rneoj_getPath_str_test.R
