RSelenium and Java Heap Space

I’m in the process of deploying a scraper on a DigitalOcean instance. The scraper uses RSelenium with the PhantomJS browser. I ran into a problem though. Although it worked flawlessly on my local machine, on the remote instance it broke with the following error: Selenium message:Java heap space Error: Summary: UnknownError Detail: An unknown server-side error occurred while processing the command. class: java.lang.OutOfMemoryError Further Details: run errorDetails method Execution halted Clearly Java a memory issue.
