R RSelenium/seleniumPipes Unknown error: cannot find Chrome binary

I try to connect with Selenium in R using the Chrome browser on Win10.

I installed Chrome 74.0.3729.61 and added the chrome.exe path to the Environment Variables.

devtools::install_github("johndharrison/seleniumPipes")
devtools::install_github("ropensci/Rselenium")

#start selenium
selServ <- selenium()
# check ports
selServ$log()$stderr 
# conect using port
sel <- remoteDr(browserName = "chrome", port = 4567)

gives me the following error message:

Called  newSession  - Try no:  1  of  3 

Called  newSession  - Try no:  2  of  3

I found some guidance for Python (Cannot find Chrome binary with Selenium in Python for older versions of Google Chrome) and c# (Selenium WebDriver - Could not find Chrome binary), however, I do not know how to implement it in R.

IMHO you need to download and run chomedriver.exe(if you are using Windows 10, as you mentioned) before to use selenium.
Could you try below solution?

Solution 1. on command window

java -Dwebdriver.chrome.driver="C:/{yourPath}/selenium/chromedriver.exe" -jar "C:/{yourPath}/selenium/selenium-server-standalone-3.141.59.jar" -port 4567

or

Solution 2. direct use R script 

rstudioapi::terminalExecute('java -Dwebdriver.chrome.driver="C:/{yourPath}/selenium/chromedriver.exe" -jar "C:/{yourPath}/selenium/selenium-server-standalone-3.141.59.jar" -port 4567')

Yes, both are same command exactly. You are able to use anyone you want.
