Ok, an obligatory note: opinions expressed here are mine and not those of my employer.

comment How to implement FittedModel like objects
@Mr.Wizard I don't have a strong opinion on the matter. I would go with whatever Gabriel decides.

comment How to implement FittedModel like objects
@Mr.Wizard I think this question may have this more conceptual component too, e.g. how DownValues and SubValues are used to implement some properties of such object.

Look also at SubValues[FittedModel] for those properties you were missing.

comment How do I add options to a built in function, which only apply to a certain class of argument?
I can't reproduce this. I can run your definition (DateString) with no problems, and no errors reported. I am on Win7 64 bit, and tested on both M8 and M9.

Then we are back to my original request: please add an example illustrating the error. Generally, it is a good practice to provide fully self-contained description, not to make us guess the missing parts.

I dont see why do you need that definition at all (the one with Options). The following input, for example, works without a problem: DateString[zoned[{1959, 8, 29, 0, 0, 0}], {"Year"}, ShowZone -> True].

What error do you get? Can you add some sample use which leads to an error?

comment Is there a faster way to compute the endpoint for a DateRange given the start, step, and length?
I agree. While there are some problems with the SE model, nothing is perfect, and it most definitely works, and works pretty well.

comment Is there a faster way to compute the endpoint for a DateRange given the start, step, and length?
Yeah, this fastest gun in the West is really a problem. I view it as one of the shortcomings for the SE model, which promotes competition far more than collaboration. OTOH, it is not obvious to me whether or not the decrease of degree of competition would be better, since lots of folks appreciate this element of RPG, making it more fun to answer.

@MarkusRoellig Thanks:). Well, it's been already a while ago, time's running.

@Ajasja Which is not dissimilar, since Compress is effectively used by images.

comment Installing RLink on Linux
@murray I am fully aware of that, thanks. There are some technical problems for Macs, hopefully they will be resolved soon, as I already mentioned.

comment Using a different version of R with RLink on Windows 7
@murray Well, it has been reported that you can use external R on at least some flavors of Linux. I can't promise anything, but I hope to be able to address this issue for the 9.1 release.

@murray Well, I sort of implicitly included them into the checks I was talking about. But may be it is worth mentioning explicitly. Edited.

comment Using a different version of R with RLink on Windows 7
@Szabolcs Why don't you make that an answer? Because that's the only sensible answer there is. And if it fails, I really want to know about it.
