Re: [Rd] forwarded: bug (?) in cut.POSIXt with breaks=integer
PS a parallel problem seems to occur in cut.Date ... cut.POSIXt and cut.Date both allow breaks to be a single integer specifying the number of breaks, and both call if(is.null(labels)) levels(res) - as.character(breaks[-length(breaks)]) near the end of the function, which breaks (so to speak) if length(breaks)!=length(levels(res))-1 I could keep working on a patch if requested, but probably won't otherwise.

[Rd] Fixing html help port in 2.10
I noted that the new html-help in 2.10 under Windows uses a random port on my computer. This cause a problem, because when I create a link such as: http://127.0.0.1:28027/library/stats/html/addmargins.html this is for one-time use only. Is it possible to fix the port?

Re: [Rd] Question when compiling source code with VC++
Thank you for this clarification, neither did I know that it was written by Brian Ripley (although now this seems to be obvious) nor that the advice is already 10 years old. Thus please allow me to re-phrase my question: Dear Prof. Ripley: 1, Why did you propose the option /MT instead of option /MD? 2, Will the proposed settings to build the DLL still be valid for the upcoming Windows 7?

I didn't write that: I've got no experience with VC++. It was Brian Ripley who wrote it, and the log says he wrote it in 1999. So I'd guess that it isn't bad advice (having lasted 10 years without a change), but I guess it's possible that it is no longer optimal.

If whatever you're building has something to do with R then this is no issue since you get the port from R. And if you're working on something unrelated to R then nothing prevents you from using the same approach that old R versions used -- create a static file that points to the correct URL for the current session (like help links in 2.9 and earlier).

Re: [Rd] Fixing html help port in 2.10
You still didn't answer the crucial question -- what are you trying to do? Creating some frequently used links in a browser. Static works, but it is a nuisance that I have to change is every time I get a new version. I now created a virtual link to it (works in Windows too).

Re: [Rd] Question when compiling source code with VC++
Dear Simon, Of course I have read the MS docs, especially: http://msdn.microsoft.com/en-us/library/2kzt1wy3.aspx which says, that /MT uses the multithread, static version of the run-time library. As far as I understand this is not what most people want since to my knowledge most programs seem to use the /MD option. I also know that option /MT works pretty well for source code of R-packages compiled for Windows XP. My second question is if it will also work with Windows 7 which I do not have yet. Furthermore, you may have realized that since some time I am trying to find out why in my case neither option works on Vista, see my more detailed question at: https://stat.ethz.ch/pipermail/r-devel/2009-September/054843.html If you have any idea in this case I would appreciate it very much.

The reason it is random is the worry that multiple R instances on the same machine might collide. All processes on the machine see the same ports. Related: I'd like to suggest an option/environment variable that specifies the set of port numbers sampled from, e.g. 6800:6850 or similar. The reason is that in some places, the user don't have admin privileges on the computer and most/all ports are blocked from running servers, and there is a sysadm that needs to approve each port to be unblocked. With such a security polices it is possible to have the smaller set of port number unblocked (but not the full 0-65535 range). This applies at least to regular users on Windows.
