Hi, i'm not using an eeepc, but i think your slax + sage + python +... would be really interesting for many ppl using this sort of software. Means, an official ISO image would be fantastic :D This distro is not only for EeePC, but it can run on other PC and Notebook. Only I had added some

[sage-support] R interface issues

2008-05-15 Thread shahab
Hi, Maybe I am doing something wrong. I used to work with rpy and it worked fairly well. I am having trouble with the new R interface. For example, I can't explain why: r.summary(r.c(1,2,3,11,2,3,4,5)) works perfectly fine but: x = r.cbind(1, 1:7) gives me a syntax error and y =

Hi Shahab, disclaimer: I have never used R. But hopefully my remarks make sense. On May 15, 9:49 am, shahab [EMAIL PROTECTED] wrote: x = r.cbind(1, 1:7) gives me a syntax error and It complains about the colon in 1:7. Do you mean 1/7 or 1.7? Both work: sage: x = r.cbind(1,1/7) sage: x

great: that's exactly the case. the adjacency matrix of transitive closure is the reachability matrix, so this is a good workarround. On 14 Maio, 16:16, Jason Grout [EMAIL PROTECTED] wrote: Jason Grout wrote: William Stein wrote: On Wed, May 14, 2008 at 6:57 AM, David Joyner [EMAIL

Willaim, I'll give Sage another try when I get a new computer (which hopefully isn't too far off), or when there is a native Sage for windows. Thank you for your time. For now, I will stick to straight Python. I admire your dedication to the Sage project and wish you success. I will give Sage

I copied sage 3.0 binary to a different location (which worked fine). I also moved the directory sage_notebook to a different location. When I start the notebook pointed to this new directory, it starts fine but all the users info are gone. All the worksheets are still there. If I add a user to

Are you certain that you are getting the new path correct? I've thought that this happened to me before, and it turned out that I wasn't specifying the new notebook directory correctly. I have had two mysterious cases of worksheets disappearing from the noteboook (in the sense that they didn't

I have made that mistake before but this time the path is correct. The user folders under the /worksheet exist and once I added a new user with the same name (user1) to the server, nothing shows up in the new notebook window. But when I create a new worksheet for this user1, the worksheet folder

Is this a bug? sage: 3 == pi 3 == pi sage: i == i I == I Shouldn't this return False and True, respectively? I know this works: sage: 3 == pi.n() False sage: 3 == RR(pi) False but I sort of expect pi to act like the number pi when used with things like == or , without using the .n()
