I've wrote some code to simulate a random walk in 2 dimensions on a lattice. Basically I want to add something in to make it plot it point by point so you can see what is going on. Heres my code for the random walk in 2d RW2D<-function(N) { i<-0 xdir<-0 ydir<-0 xpos<-vector() xpos[1]<-xdir ypos<-vector() ypos[1]<-ydir for (i in 1:N-1) { r<-runif(1) if(r<=0.25) {xdir<-xdir+1} if(r>0.25 && r<=0.5) {xdir<-xdir-1} if(r>0.5 && r<=0.75) {ydir<-ydir +1} if(...

Hi all, My app uses prefixes for user-defined labels and directory names. Since these are case-sensitive, I chose XLABEL and XDIR respectively. Labels and directories may start with an upper-case, so a ":" is always inserted between the prefix and the term itself. These prefixes are mapped with add_boolean_prefix to "dir" and "label". Let's imagine I index a document with "XLABEL:xapian...

...ble. SCRIPTING/OTHER LANGUAGES 7. -x argument which works similar to the same argument in Perl/Python/Ruby to allow a batch file and an R file to be combined. For example: python -x prog.py skips first line of prog.py allowing non-UNIX forms of #!cmd perl -x prog.pl or perl -xdir prog.pl strips off text before !#perl line and possibly cd's to directory (if one is given). ruby works same way. Thus one could write: Rscript -x myfile.bat and combine a Windows batch file and an R file into myfile.bat, say. 8. tcltk a. some easy way to run R minimized but have a tclt...

Hi, It's been a while since I created my smbpasswd file, and therefore it is no longer in synch with my Unix file. I've added and removed users over time, and now I need a way to update the 'smbpasswd' file without losing the encrypted passwords that are already in place (ie. I don't want to just run 'makesmbpasswd.sh' again). So, I've written the

Okay, everything as the first large one I sent today, with a few extra mods. _PATH_MAILDIR is only used in sshd.c, that I can see, so moved the #ifdef from config.h.in to there. several files had __progname defined in the middle of the code, as well as at the top of the code, so cleaned those out. all the fixes for u_int32_t -> uint32_t and u_int16_t -> uint16_t, plus added appropriate
