Yes, you are right about needed work.

Yes, the implementation would not be the main problem, but the maintenance. For hierarchical views, there needs to be much more communication and coordination between the maintainers of related views. My idea was to keep the work low for the maintainers...hoping that there would be more people volunteering to maintain a view related to their field of research or application.

Hello! First of all congratulations for a nice approach to present "R fields" in more coherent way. When I started with R I was often frustrated with long list of packages, similarities between them, ... If I would take a slow approach (one thing at a time) things would be easier from the start, but usually one wants to know what a new program is capable of.

I think that there is a lot of "fields" where this views cover the same stuff. When I first read about ctv I thought it will be implemented more in somewhat "hierarchical" or kind of "multiple" way, since for example linear models come usefull in many different fields and some people might never look under "Econometrics" view as Paul stated. I realize that "hierarchical/multiple" is far from easy and I do not have any clear idea how to implement it, but it would probably easier to maintain larger set of views in such a way and it would be easier to generate new ones. -- Lep pozdrav / With regards, Gregor GORJANC --- University of Ljubljana Biotechnical FacultyURI: http://www.bfro.uni-lj.si/MR/ggorjan Zootechnical Department mail: gregor.gorjanc bfro.uni-lj.si Groblje 3 tel: +386 (0)1 72 17 861 SI-1230 Domzale fax: +386 (0)1 72 17 888 Slovenia, Europe __ R-devel@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

It is certainly a better starting point than anything I have related to Matlab. I think this also underlines the bigger problem too. There is actually a very large amount of R documentation, but it is often hard for someone with a particular background to know were to start. Even though I now know this document exists, it seems a bit difficult to actually find it from CRAN. If I Google "R and Octave" I get it immediately, but it doesn't show up with "R and Matlab." It seems to me that the "view" idea may provide a very good mechanism that will work even when you really don't know where to start. (BTW, this is an example, I don't really know much about Matlab.)

Yes, that is, of course, an obvious idea but it requires more coordination between the different views, hence we've decided not to support hierarchically ordered views. Re: "ControlTheory". If someone would raise his hand and provide a view for that, it would be great. It could, of course, link to the "Econometrics" view (and vice versa) but they wouldn't have a formally defined subset in a "TimeSeries" view. > Other things that might be useful are various programming views, like > a Matlab view, and an SPSS view. I'm not sure what you have in mind here, because I would think that this amounts more to using the language in general than using certain packages.

Yes, there have been discussions about stuff like that on R-SIG-Finance. I think the presence of an "Econometrics" view shouldn't keep people from setting up an econometrics wiki if they want something like that. But my personal preference would be that someone starts collecting and maintaining code snippets in an R package rather than a wiki. The gregmisc bundle is a place for something like that with general statistical functionality. And back then, when this was discussed on the finance SIG, I suggested that someone who has some critical mass of code would start something similar for finance/econometrics/time series stuff.

Just to be sure I do understand, would you expect there might also be a "Time Series" view, which would probably overlap some with the "Econometrics" view?
