Dear all, how can I convert an m x n incidence matrix into an m x m adjacency matrix or an n x n adjacency matrix? The current matrix contains binary data, hence the new matrix would contain counts of common occurrences. Thank you for your help. Phil

Dear R community, is there an easy way to convert an adjacency list (or a data-frame) to a non-symmetric matrix? The adjacency list has the following form: person group 1 Sam a 2 Sam b 3 Sam c 4 Greg a 5 Tom b 6 Tom c 7 Tom d 8 Mary b 9 Mary d I need the data in a matrix with persons as rows and groups as columns: a b c d Sam 1 1 1 0 Greg 1 0 0 0 Tom 0 1 1 1 Mary 0 1 0 1 I know that there

Dear R-Fans, The more I work with matrices (e.g., data.frames) the more I think it would be helpful to have functions to apply (several!) mathematical and/or logical operators column- or row-wise in a matrix. I know the function apply() and all its derivates (e.g., lapply) but I think this does not help for solving (e.g.) the following task: assume there is a 3x3 matrix: 1 2 4 4

Dear useRs, last week I asked you about a problem related to isoMDS. It turned out that in my case isoMDS was trapped. Nonetheless, I still have some problems with other data sets. Therefore I would like to know if anyone here has experience with how well isoMDS performs in comparison to other non-metric MDS routines, like Minissa. I have the feeling that for large data sets with a high

Hi, This is my first message to this list. It would be great if people here could help me with the following problem (self-contained code example below): I have a list of matrices and would like to apply a summary function to the matrices in the list. The matrices represent social networks, therefore I need to apply some specialized summary functions provided by the ergm package. These

Hi All, I''m just starting out with RoR and scriptaculous so I hope this is the right forum for this question. :) I''d like to use the drag & drop feature to allow users to copy text from a browse/search result to a text box across windows. For example if a user wants to browse for an existing tags, that list might be too long for a auto complete textfield to be helpful. So

Testing Samba 2.0.7pre2 I found that creating new shares with SWAT does not work, just the Samba-logo appears, but nothing else. -- Stephan D?hr <duehr@ID-PRO.net> (Support) * ID-PRO Deutschland GmbH * Am Hofgarten 20 * D-53113 Bonn * Tel +49 228 4 21 54 0 * Fax +49 228 4 21 54 59 * http://open-for-the-better.com/

I've got Metal Gear Solid running fairly smoothly in Wine 1.3.31 on Mac OSX Snow Leopard, with no instability or crashes so far. When I start the game, the sound acts as it should-- however, going past the main menu (such as to Briefing or New Game) causes the sound to stop working. How can this issue be fixed? Here's my console output: Code:
