R is often used to teach statistics at universities, so there may be hundreds of thousands, if not millions, of installations around. Here are the Amazon data on "Introductory Time Series with R (Use R!)" published by Springer (272 pages, 45$) Amazon Best Sellers Rank: #72,412 in Books (See Top 100 in Books) Statistical or "R by Example (Use R!)" (350+ pages, 44$) Amazon Best Sellers Rank: #72,627 in Books which looks good to me. But notice that "The Art of R Programming: A Tour of Statistical Software Design" published by No Starch Press fares much better: (400pages, 25$) Amazon Best Sellers Rank: #9,454 in Books (See Top 100 in Books) Mathematics Note that "R Cookbook (O'Reilly Cookbooks)" (400+ pages, 25$) has even better scores: Amazon Best Sellers Rank: #8,835 in Books (See Top 100 in Books) IMHO this data shows that Springer wants to charge much more for its books (and its sales are perhaps 10 times less, at least on Amazon, see http://www.fonerbooks.com/surfing.htm), for reasons that do not look convincing to me. Looks like Springer behaves in this market as Apple in personal computers, charging more for reasons not always clear...

[sage-devel] Re: Singular fails to build in Sage 5.9
Oh... I see. I am ignorant on what various flags mean. Let me summarize my problems and see if I get them right: 1) my gcc compiler confuses c and c++ programs. 2) I want to solve 1) by forcing sage to use the gcc-4.7.2. but the problem is that the copy of gcc that come with sage won't build from my system gcc... (see the my 3rd message in this discussion) Am I right? Any ideas on what else can I try?

Here's an article on R http://www.nytimes.com/2009/01/07/technology/business-computing/07program.html?pagewanted=all and it doesn't mention Springer. How many copies do you need to be among the best-sellers for Springer? Maybe 3,000? How many copies of R are there, and how many people actually buy a book to use free software? How many would buy a bunch at US$65 each? (Certainly some, but perhaps because the book teaches something other than documenting R. Like statistics, data analysis, etc. ) Regarding just "R" how good is the free documentation available here: http://www.r-project.org/ ? While I would not like to discourage anyone from writing documentation on anything, all the traditional motivations for publication seem to be lacking for a Springer series. Here are some of the traditional motivations. 1. The author hopes to make money from royalties. 2. The author hopes to become famous (or gain tenure) from the book. 3. There is a gap in the literature and the author and publisher wish to remedy this for non-financial reasons, perhaps political, moral, religious; making friends, influencing enemies. 4. Some kind of creative impulse. You may have some other ideas for motivation, but these come to mind. Insisting on Creative Commons means, it seems to me, that you would be working to make sure that the only people who might make money from sales would be Springer. Of course Springer would be biased in favor of ANY way of adding to their list, as long it has some prospect of making some money for them, and they are used to sales of very short runs. It falls short of their activities with journals -- the author surrenders all control in return for no royalty, and Springer charges big bucks for library subscriptions -- but it is something. An intermediate stance, where an author writes a good/popular book and gets paid royalties on sales, is a common although rarely lucrative (for the author) choice. I personally doubt that combinatorics with Sage would be a big seller, but if you have already written it and Springer would like to publish it, and it doesn't interfere with your ownership, it seems like you have nothing to lose. But make sure you don't give away something unintentionally, whether it is right or your valuable time and energy.

I am using Archlinux, so there is not g++ separately. And gcc decides whether the program as a C or C++ program in the following way. |gcc file.C # uppercase .C (or .cpp) will process as C++ gcc file.c # lowercase .c will process as C| see http://unix.stackexchange.com/questions/34654/c-compile-in-arch-linux-with-no-g-package-in-repositories for details. So the question is what can be changed so that the gcc in my machine will interpret compile weight0.c as a C++ program... I wonder why I didn't encounter such a program earlier... perhaps it's the pre-release reversion that causes that problem. Also can I use force it to use the gcc (I suppose gcc-4.7.2.p1.spkg is the one) that comes with sage to compile? Yes it looks tricky. It could very well be a regression as it compile with the C compiler and not the C++ compiler on my box with gcc 4.6.3 (gentoo). That being said gcc is very permissive and one day someone may decide to cut that one off. Would you believe that 2 days ago I accidentally configured octave with CXX=gcc-4.7.1 and I almost completely compiled it before being shot down by such a problem [octave is mostly c++]. The problem is not that a C compiler is used to compile weight0.c, but that cf_gmp.h includes in the first place. (Although bits/c++config.h is valid C code as well, it's not in the [C++] include path if you compile a file as C code which includes it.) But it seems ArchLinux's broken gcc/g++ behaviour triggers the problem. Pong, could you upload/attach your cf_gmp.h? (Should be located in $SAGE_ROOT/spkg/build/singular-3-1-5.p7/src/factory/, but only after a failed build or if you use 'sage -f -s ...', or alternatively set SAGE_KEEP_BUILT_SPKGS=yes.) I'll take a look at the full Singular build log you attached earlier. -leif -- () The ASCII Ribbon Campaign /\ Help Cure HTML E-Mail -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

It could very well be a regression as it compile with the C compiler and not the C++ compiler on my box with gcc 4.6.3 (gentoo). That being said gcc is very permissive and one day someone may decide to cut that one off. Would you believe that 2 days ago I accidentally configured octave with CXX=gcc-4.7.1 and I almost completely compiled it before being shot down by such a problem [octave is mostly c++]. Anyway you can certainly force sage's gcc by setting SAGE_INSTALL_GCC=yes before building sage.

Re: [sage-devel] Singular fails to build in Sage 5.9
Hum I see what you are saying. Well my case is a bit tricky but I think I'm not alone. I am using Archlinux, so there is not g++ separately. And gcc decides whether the program as a C or C++ program in the following way. gcc file.C # uppercase .C (or .cpp) will process as C++ gcc file.c # lowercase .c will process as C see http://unix.stackexchange.com/questions/34654/c-compile-in-arch-linux-with-no-g-package-in-repositoriesfor details. So the question is what can be changed so that the gcc in my machine will interpret compile weight0.c as a C++ program... I wonder why I didn't encounter such a program earlier... perhaps it's the pre-release reversion that causes that problem. Also can I use force it to use the gcc (I suppose gcc-4.7.2.p1.spkg is the one) that comes with sage to compile?

But the killer thing I think is that weight0.c is a justly compiled with the c compiler but if you want to use this header, g++ should be used. One man's opinion at any rate.
