I just installed RSelenium from github (I have the same issue when I install it via cran) and I get the following error in windows machine:
Error in if (file.exists(file) == FALSE) if (!missing(asText) && asText == :
argument is of length zero
In addition: Warning message:
running command '"wmic" path win32_process get Caption,Processid,Commandline /format:htable' had status 44210
From the function startServer() this is the part that is producing the error:
system2("wmic", args = c("path win32_process get Caption,Processid,Commandline",
"/format:htable"), stdout = TRUE, stderr = NULL)
When I run this part I get the following:
character(0)
attr(,"status")
[1] 44210
Warning message:

It is an issue with Win 7.
A htable XSL stylesheet is used to format the output of WMIC path win32_process
It results as a mismatch when using regional settings. Possible workarounds given are:
Copy or move the C:\Windows\system32\wbem\en-US*.xsl files up into the C:\Windows\system32\wbem\ folder.
Change your regional settings to match your Windows language version, log out and back in.
Specify the full path: WMIC process get /format:"%WINDIR%\System32\wbem\en-US\csv"
as noted in wmic error (invalid XSL format) in windows7

I am using R in Windows from Amazon AWS.
However when I use the same code from my local Mac, I have no problem.
Any pointer how to resolve this issue will be highly helpful.
Thanks,

I am trying to learn using RSelenium. I am stuck with just trying to start the server using rsDriver. I am simply trying to run the code below and got the following error:
rD <- rsDriver()
checking Selenium Server versions:
BEGIN: PREDOWNLOAD
Error in open.connection(con, "rb") :
Peer certificate cannot be authenticated with given CA certificates
I searched around stack overflow and found out we can give options to rsDriver using below but I still got error:
my_extra <- list("--ignore-ssl-errors=true", "--ssl-protocol=tlsv1", "--web-security=no")
rs <- rsDriver(extraCapabilities = my_extra)
checking Selenium Server versions:
BEGIN: PREDOWNLOAD
Error in open.connection(con, "rb") :
Peer certificate cannot be authenticated with given CA certificates
Is there anything else I am missing?
for httr::GET function, I am able to bypass the SSL Certificate using:
set_config(config(ssl_verifypeer=0L)).
But this method does not work for RSelenium::rsDriver.

rsDriver uses the binman package to handle the downloading of relevant binaries. The selenium project lists its release in a JSON file at https://www.googleapis.com/storage/v1/b/selenium-release/o
You should have the same issue if you try:
jsonlite::fromJSON("https://www.googleapis.com/storage/v1/b/selenium-release/o")
You can mock the relevant curl fundtion using something like:
my_new_handle <- function(...){
print("mocking")
h <- .Call(curl:::R_new_handle, PACKAGE = "curl")
curl:::handle_setopt(h, ..., ssl_verifypeer = FALSE)
h
}
testthat::with_mock(
`curl::new_handle` = my_new_handle,
{
selCommand <- httr::with_config(config(ssl_verifypeer=0L),wdman::selenium(retcommand=TRUE))
}

I am new to R and am trying to web scrape a jsp page to collect data. The page I want scrape from is: https://www.taxpayerservicecenter.com/RP_Search.jsp After I get a browser to open this url, I want to select neighborhoods, and scrape all the data there.
Also, is there an easier/better way to do this? This page has buttons and forms so it isn't as straight forward as say, scraping from a wikipedia page.
library(RSelenium) #passes
checkForServer() #passes
startServer() #passes
remDriver <- remoteDriver(remoteServerAddr="localhost", port=4444, browserName="firefox")
The following line is where I receive the error:
remDriver$open() #opens a browser, get the farthest w firefox
This is the error message I receive. I have searched everywhere for how to solve this!:
> remDriver$open() #opens a browser, get the farthest w firefox

I followed the instruction on the Github. It returned me an error like this:

Error in curl::curl_fetch_memory(url, handle = handle) :

In addition: Warning message:

Then, I tried to download the repo zip file and installed the shinyTable from local zip file in R studio. After that, I library(shinyTable). It return me an error.

I had similar issues recently. Can you try this:

install_git("https://github.com/trestletech/shinyTable")

It looks like you don't currently have the phantomjs.exe on your path. More details can be found in the RSelenium "Saucelabs" vignette http://cran.r-project.org/web/packages/RSelenium/vignettes/RSelenium-saucelabs.html#id2a.
So download phantomjs from here: http://phantomjs.org/download.html and put the exe in your path.
