Hi Alex,<br>
<br>
Thanks to your help, I've solved the probles for running './run.py -s figure-3-data-propagation-vs-time'. But, there is another problem about Rscript.<br>
<br>
I've already installed Rscript and 'ggplot2, proto, doBy' correctly according the web page "<a href="https://github.com/cawka/ndnSIM-nom-rapid-car2car'">https://github.com/cawka/ndnSIM-nom-rapid-car2car'</a>.<br>
<br>
When I run the command './run.py -s figure-3-data-propagation-vs-time', the screen displays as following:<br>
<br>
./build/car-relay --run=8 --distance=170 --fixedDistance=10000<br>
./build/car-relay --run=9 --distance=170 --fixedDistance=10000<br>
./build/car-relay --run=10 --distance=170 --fixedDistance=10000<br>
Error in library(ggplot2) : there is no package called 'ggplot2'<br>
Calls: suppressMessages -> withCallingHandlers -> library<br>
Stop<br>
<br>
Could you solve this problem?<br>
<br>
Regards,<br>
