remDr$open() Unexpected Error when using RSelenium with phantomjs

Question

I am using the following code

remDr <- remoteDriver(browserName = "phantomjs")
URL <-"http://www.soccer24.com/kosovo/superliga/results/#"
remDr$open()

I get the following error:

Error:   Summary: UnknownError
     Detail: An unknown server-side error occurred while processing the command.
     class: java.lang.IllegalStateException

I don't know why am I getting the error?

It looks like you don't currently have the phantomjs.exe on your path. More details can be found in the RSelenium "Saucelabs" vignette http://cran.r-project.org/web/packages/RSelenium/vignettes/RSelenium-saucelabs.html#id2a.

So download phantomjs from here: http://phantomjs.org/download.html and put the exe in your path.
