When trying to run the RSelenium examples to try and carry out some webscraping I get the following error message when trying to open up the server...I'm not sure what the issue is...
library(RSelenium)
startServer()
# use default server initialisation values
remDr <- remoteDriver$new()
# send request to server to initialise session
remDr$open()
[1] "Connecting to remote server"
$message

Then there are some stackTrace info, all of which are NULL
Any ideas on how to solve this issue?
Also when trying to run a demo I get the following issue...(but think its because RSelenium::startServer() wasnt run first)
> demo(selExecJSexample)

Error in function (type, msg, asError = TRUE) : couldn't connect to host
This was an issue with the selenium release cycle being slightly out of sync with the firefox release cycle. http://selenium-release.storage.googleapis.com/index.html now contains an updated Selenium Server (currently version 2.43.0). Running RSelenium::checkForServer with update = TRUE will update the Selenium Server locally and the most recent firefox should function:
> library(RSelenium)
> checkForServer(update = TRUE)
