I can't get anywhere with R selenium. Here's the first step and my output:

library(RSelenium)
rD <- rsDriver()
# checking Selenium Server versions:
#   BEGIN: PREDOWNLOAD
# BEGIN: DOWNLOAD
# BEGIN: POSTDOWNLOAD
# checking chromedriver versions:
#   BEGIN: PREDOWNLOAD
# BEGIN: DOWNLOAD
# BEGIN: POSTDOWNLOAD
# checking geckodriver versions:
#   BEGIN: PREDOWNLOAD
# BEGIN: DOWNLOAD
# BEGIN: POSTDOWNLOAD
# checking phantomjs versions:
#   BEGIN: PREDOWNLOAD
# BEGIN: DOWNLOAD
# BEGIN: POSTDOWNLOAD
# [1] "Connecting to remote server"
# Error in checkError(res) : 
#   Undefined error in httr call. httr output: Failed to connect to localhost port 4567: Connection refused
# In addition: Warning message:
#   In rsDriver() : Could not determine server status.

What did I miss ?

In case that is still useful, I was running into the same problem today and was able to fix it by installing a Java Development Kit (Java SE Development Kit 11.0.1).

I was getting an error message from my computer to that effect, as well as the same R error as mentioned in this question, and it fixed it.

For a reproducible example, I was able to replicate this tutorial.

Per the Cran vignette I had to run:

shell("docker-machine ip")

Then set the remoteServerAddr to the IP which was returned.
