hi all why does the following not work??? this was someone elses code and i couldnt explain why it doesn't work. m=matrix(c(0,0),2,1) v=matrix(c(1,0,0,1),2,2) Y=function(X1,X2,mu=m,V=v) { X=matrix(c(X1,X2),2,1) a=(1/((2*pi)*sqrt(det(V))))*exp((-0.5)*(t(X-mu)%*%solve(V)%*%(X-mu))) a[1] } x1=seq(-1,1) x2=x1 Z=outer(x1,x2,FUN="Y",mu=m,V=v) persp(x1,x2,Z) my code:

I want to implement the following algorithm in R: I want to split my data, use a t test to compare both means of the groups to see if they significantly differ from each other. If this is a yes (p < alpha) I want to split again (into 4 groups) and do the same procedure twice, and stop otherwise (here the problem arises). As a final result I would have different groups of data. I made some

Dear All, I like to simulate a physiologically based pharmacokinetics model using R but am having a problem with the daspk routine. The same problem has been implemented in Berkeley madonna and Winbugs so that I know that it is working. However, with daspk it is not, and the numbers are everywhere! Please see the following and let me know if I am missing something... Thanks a lot in advance,

Hello, we have 80 text files with matrices. Each matrix represents a map (rows for latitude and columns for longitude), the 80 maps represent steps in time. In addition, we have a vector x of length 80. We would like to compute a regression between matrices (response through time) and x and create maps representing coefficients, r2 etc. Problem: the 80 matrices are of the size 4000 x 3500 and we

I have a scatter plot with 10000 points.? I would like to add a line that bins every 50 points and connects the average of each bin.? I'm looking for something similar to line type "m" in Stata. With this dataset of 10000 points, I would also like to bin the data and make boxplots at certain intervals, so that I have a set of boxplots to represent each bin.? I would also like the

I'm doing a new install, and everything seems to have gone fine apart from the incredible amount of time it's taken. It does have 6 x 4TB drives in RAID6 and I am installing from a USB DVD drive as I had no SATA ports left, but this is getting rediculous. I chose a simple install (the one above file and print server) and added Postgresql but that was about it. It took over 5 hours

Hello, I have been looking for functions for calculating the within-groups variance and between-groups variance, for the case where you have several numerical variables describing samples from a number of groups. I didn't find such functions in R, so wrote my own versions myself (see below). I can calculate the within- and between-groups variance for the Sepal.length variable (iris[1]) in

I am new to linux and am currently using Kubuntu 11.04 on a coby 10in netbook with no cd drive. I have ISO files of the diablo II install play cinematics and LOD discs. i was wondering if it was possible to mount and play off of those files. something similar to Daemon tools. i tried Acetone ISO but after i mounted nothing happend. I googled for a while and came to this site and read alot about

Hi, I am trying to do some simple ingress limiting based on fwmark. I know the ability and sense to do INGRESS limiting is ehm... limited ;-) but still I want to try it. I tried several things. === 1 === tcq ingress handle ffff: tcf parent ffff: protocol ip prio 1 handle 1 fw police rate 12mbit burst 10k drop tcf parent ffff: protocol ip prio 1 handle 2 fw police rate 10mbit burst 10k drop

Hi all, I'm a newbie and I have a configuration problem with Asterisk. Seems that I'm not able to call an outbound number. I'm quite sure that it is a configuration problem, but I'm not able to find out where is the mistake, even reading several docs to www.voip-info.org. I do not have a good knowledge of Asterisk, I'm not very familiar with its configuration and I've a

I see in NexentaStor''s announcement of Community Edition 3.0.3 they mention some backported patches in this release. Aside from their management features / UI what is the core OS difference if we move to Nexenta from OpenSolaris b134? These DeDup bugs are my main frustration - if a staff member does a rm * in a directory with dedup you can take down the whole storage server - all with

Hi all, I find the whole QOS area quite fascinating and I''m considering starting a small business to try and push QOS solutions in general to small and medium sized businesses. I would of course be happy to push Packeteer and Cisco kit to those who want it, but to be honest the product of choice from a cost and functionality point of view seems to be linux I would appreciate any

There is still feedback and/or minor adjustments being asked for wrt. this series. These changes have been sitting for more than a week which is a bit rediculous. Please resubmit these changes once everything is resolved to everyone's satisfaction, thanks.
