RSelenium Invalid call to server

when I run the introductory code in R,

require(RSelenium)
remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4444, browserName = "chrome")

remDr$navigate("http://www.google.com")

I get the error

Invalid call to server. Please check you have opened a browser.

Error in queryRD(paste0(serverURL, "/session/", sessionInfo$id, "/url"), :

I added the line

remDr$open()

between the remoteDriver assignment and the remDr$navigate() command, in addition to editing the system path, and was able to achieve success.
