RSelenium, Can't start server

I'm trying to use RSelenium for web-scraping purposes behind a login and I can't get the server to run.

Current result:

library(RSelenium)
startServer()
remDr <- remoteDriver(port = 4444,
                      browserName = "firefox") 
remDr$open()
# [1] "Connecting to remote server"

Error:     Summary: UnknownError
   Detail: An unknown server-side error occurred while processing the command.
   class: org.openqa.selenium.firefox.NotConnectedException

I've tried running the server myself by downloading and trying to open it (nothing happens).

Try below.

rD <- rsDriver(port=4444L,browser="firefox")
mybrowser <- remoteDriver(browserName = "firefox") 
mybrowser$open()

RSelenium has problems to establish serwer at the begginig on respective port. Subsequently we are telling which driver should be used.

This was a tough one and stopped me for a couple of days when I could search on it. In the end I uninstalled Firefox and installed version 37.0 while also disabling the update service. That fixed it for me and RSelenium works fine again.

Run the following code first then it should work:

RSelenium::checkForServer()

This line of code installs the selenium server which you need for running RSelenium commands.
