    Assuming you got

    library(RSelenium)
    startServer()
    remDr <- remoteDriver()
    remDr$open()
    remDr$setWindowSize(width = 800, height = 300)
    remDr$navigate("https://www.r-project.org/about.html")
    

    You could scroll to the buttom like this:

    webElem <- remDr$findElement("css", "body")
    webElem$sendKeysToElement(list(key = "end"))
    

    And you could scroll to the top like this:

    webElem$sendKeysToElement(list(key = "home"))
    

    And in case you want to scroll down just a bit, use

    webElem$sendKeysToElement(list(key = "down_arrow"))
    

    The names of the keys are in selKeys.
