Why am I getting a syntax error with RSelenium in Docker?

I am trying to follow this tutorial RSelenium and scraping as it seems to be just what I am trying to do. Use RSelenium to scrape a Javascript website.

I have installed Docker and all seems good, but I run into problems with the following command:

remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox'")

which I think is intended to be:

remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox")

However, both versions return this error:

bash: syntax error near unexpected token `('

What am I doing wrong?

Here is the full log:

Your basic problem is that you're trying to type an R command at the bash shell prompt, and that's never going to work. I think you may be missing the point of the tutorial you're following:

The Docker image you're using just provides Selenium, a tool for remotely controlling web browsers. It is expected that you are running R on your host, and pointing the RSelenium library at the selenium service offered by the Docker container.

You will need to install R on your host in order to follow that tutorial.
