similar to: 2d rndom walk

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)

Greetings list, I am new to programming in R, and am using nnet() function for a project on neural networking. Firstly I wish to ask if there is any pdf explaining the algorithm nnet uses, which could tell me what the objects of the nnet class, like 'conn', 'nconn, 'nsunits', n and 'nunits' mean, and how weights are calculated. The package pdf has little or no

To compile vmkit on Ubuntu 12.04 64-bit machine, I followed the steps giving here <http://vmkit.llvm.org/get_started.html>[1]. but when I run ./configure I am getting following error- root at komal:/home/komal/Desktop/GSOC/vmkit/vmkit# ./configure >> -with-llvm-config-path=../llvm-3.3.src/configure >> --with-gnu-classpath-glibj=/usr/local/classpath/share/classpath/glibj.zip

Hi Harris Bakiras, Thanks for reply. It working now. Actually I wanted to try vmkit VM to run jruby codes. vmkit is able to run Java program, but when I try to run JRuby code then I get following error - root at komal:/home/komal/Desktop/GSOC/programs# jruby hello.rb > > Platform.java:39:in `getPackageName': java.lang.NullPointerException > > from ConstantSet.java:84:in

Hi all, This is my query. Let me explain the environment first. I have to write a perl-cgi script to add a user in samba. I will be accessing this script through apache server, in short i am making a web page to add samba user. My query is how can i add user with "smbpasswd" command and giving password as command line argument. In normal scenario i get a prompt asking for

I am working on a project to port JRuby on Embedded systems. JRuby converts Ruby code to bytecode which is executed by any JVM. For this project I am testing performance of JRuby with various available JVMs. I have chosen ARM architecture. Does vmkit support ARM architecture?

here <http://vmkit.llvm.org/> its mentioned that its portable on ARM. So simply cross-compiling will work?

Hi Kumar, There is an error on your configuration line, you should provide the path to llvm-config binary instead of configure file. Assuming that you compiled llvm in release mode, the llvm-config binary is located in : YOUR_PATH_TO_LLVM/Release+Asserts/bin/llvm-config Try to change the -with-llvm-config-path option and it will compile.

I don't know how JRuby works, maybe it uses some new feature that GNU Classpath does not provide. VMKit's openJDK version is unstable on 64 bits since package version 6b27. You can still use it for very small programs which does not need GC but that's all. It works fine on 32 bits. So you can try it on 32 bits or revert your java version to a previous one (< than 6b27) to test

Hello Kumar, Unfortunately we never experienced on ARM architecture and we are not planning to port VMKit on ARM for the moment.

I have cobbled together the following logic. It works but is very slow. I'm sure that there must be a better r-specific way to implement this kind of thing, but have been unable to find/understand one. Any help would be appreciated. hh.sub <- households[c("HOUSEID","HHFAMINC")] for (indx in 1:length(hh.sub$HOUSEID)) { if ((hh.sub$HHFAMINC[indx] == '01')

Hi Kumar, It's a mistake, we will correct that, we haven't tested vmkit on arm. As LLVM supports arm, by cross-compiling vmkit in arm/linux, it could work, but you will probably have to adapt some few parts of the code. If you plan to make the port, feel free to send us a lot of patches :) Gaël Le 22 juil. 2013 17:09, "Kumar Sukhani" <kumarsukhani at gmail.com> a écrit :

I am working on a simulation where I need to count the number of matches for an arbitrary pattern in a large sequence of binomial factors.

I have been working with the pls procedure and have problems getting the procedure to work with matrix or frame data. I suspect the problem lies in my understanding of frames, but can't find anything in the documentation that will help. Here is what I have done: I read in an 10000 x 8 table of data, and assign the first four columns to matrix A and the second four to matrix B pls <-

Hola! I am programming a class (S3) "symarray" for storing the results of functions symmetric in its k arguments. Intended use is for association indices for more than two variables, for instance coresistivity against antibiotics. There is one programming problem I haven't solved, making an inverse of the index function indx() --- se code below. It could for instance return the

If i do not have suitable driver for Linux for printer is it still possible to print to windows printer ? I tired postscript printer but it is not working. Thanks Regards,

For each entry of the first column, if that entry is found in the second column, I would like to get the corresponding index. For instance, if the first entry of the first column is 5th entry in the
