wdman (Webdriver Manager) is an R package that allows the user to manage the downloading/running of third party binaries relating to the webdriver/selenium projects. The package was inspired by a similar node package webdriver-manager.
wdman package currently manages the following binaries:
Associated with the above are five functions to download/manage the binaries:
You can install
wdman from GitHub with:
# install.packages("remotes") remotes::install_github("ropensci/wdman")
The package can also be installed from CRAN:
As an example, we show how one would run the Selenium standalone binary as a process:
The binary takes a port argument which defaults to
port = 4567L. There are a number of optional arguments to use a particular version of the binaries related to browsers selenium may control. By default, the
selenium function will look to use the latest version of each.
selServ <- selenium(verbose = FALSE) selServ$process ## PROCESS 'file50e6163b37b8.sh', running, pid 21289.
selenium function returns a list of functions and a handle representing the running process.
log functions give access to the stdout/stderr pipes and the cumulative stdout/stderr messages respectively.
selServ$log() ## $stderr ##  "13:25:51.744 INFO [GridLauncherV3.parse] - Selenium server version: 4.0.0-alpha-2, revision: f148142cf8" ##  "13:25:52.174 INFO [GridLauncherV3.lambda$buildLaunchers$3] - Launching a standalone Selenium Server on port 4567" ##  "13:25:54.018 INFO [WebDriverServlet.<init>] - Initialising WebDriverServlet" ##  "13:25:54.539 INFO [SeleniumServer.boot] - Selenium Server is up and running on port 4567" ## $stdout ## character(0)
stop function sends a signal that terminates the process:
selServ$stop() ## TRUE
By default, the
selenium function includes paths to chromedriver/geckodriver/phantomjs so that the Chrome/Firefox and PhantomJS browsers are available respectively. All versions (chromever, geckover etc) are given as
"latest". If the user passes a value of
NULL for any driver, it will be excluded.
On Windows operating systems, the option to included the Internet Explorer driver is also given. This is set to
iedrver = NULL so not ran by default. Set it to
iedrver = "latest" or a specific version string to include it on your Windows.
