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 have a shared computer. If I login with windows userA, I can run the following:
normalizePath("//mydrive/my/path", "/")
and it returns:
"\\\\mydrive/my/path"
However if login to windows under userB, I get this message:
Warning message: In normalizePath(path.expand(path), winslash,
mustWork) : path[1]="//mydrive/my/path": An unexpected network
error occurred
What does it mean? This has important consequences, as it prevents to add "//mydrive/my/path" to the .libPaths() when running under userB, e.g .libPaths(new="//mydrive/my/path"), it prints the same warning, then as soon as I try to use a package that is in this lib location, it show the ERROR:
Error in normalizePath(path.expand(path), winslash, mustWork) :
path[1]="//mydrive/my/path": An unexpected network error occurred
Here are the details of my session under userA:

Finally, I also noticed the following warning on userB, which could be linked to the same issue:

I've recently updated my Windows machine and reinstalled R3.4.0 (64bit) and igraph 1.0.1. I've previously used igraph in combination with FCMapper and it's worked perfectly.
On the new machine I keep getting the following error, even with code that previously worked without a hitch:
Error in base::.Call("R_igraph_check_finally_stack", PACKAGE =
"igraph") : "R_igraph_check_finally_stack" not available for
.Call() for package "igraph"
Error in base::.Call(.NAME, ...) : "R_igraph_finalizer" not
available for .Call() for package "igraph"
I've had a google and the previous responses indicate that it's a NAMESPACE error in the current version of the package. Any help would be appreciated!

In addition: Warning message:

From the function startServer() this is the part that is producing the error:

"/format:htable"), stdout = TRUE, stderr = NULL)
When I run this part I get the following:

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

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.
