Overall, it's not a very flexible solution for us.
It can easily be done via the domain controller: my sysadmins do it. > My work around which, at least in my unique case, is a bit more flexible > (but a little more klunky) is to add code in .First.lib that substitutes > "\\" for "//" (because I need to read a cfg file in the "data" folder of the > package when it is loaded). This should work now that I have changed dirname (to do precisely that), but as I have no suitable test examples I cannot be sure. > > > cheers, roy > > > -----Original Message----- > From: Prof Brian Ripley [mailto:[EMAIL PROTECTED] > Sent: Wednesday, June 21, 2006 1:57 AM > To: Kuraisa, Roy J (Rosetta) > Cc: [EMAIL PROTECTED] > Subject: Re: [Rd] loading library from network share (PR#8982) > > > This is not supported: network shares are a Windows 'feature' and not part > of R's conception of file paths.
