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:

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

Hello R experts: When I tried to read my data into R, it does not take # sign A subset of Exp.txt is: Experiment name assay id Varname (A1)DBA TPA 6h/DBA Acetone rep1(A1) #3 4090 A90C1 (A2)DBA TPA 6h/DBA Acetone rep2(A2) #3 4091 A91C1 The command is: Exp <- read.delim2("Exp.txt",check.names=F,as.is=T) It is excuted but gave me all the NAs. Can you all drop me a hint? Thanks

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

Hi, I am working on an example about generalized linear model in a paper using glm( ). The code is quite simple and straightforward, but the result is rediculous. The true parameter is c(4, -6), but the result is c(2.264774, -3.457114) Can anybody tell me the reason for this? Thanks a lot!!! Here is the code: g=function(t){exp(t)/(1+exp(t))} #the given link function n = 100 # sample size

I was pretty shure that W3 works great in wine, but in recent version 1.1.4 there is no image in cinematics but only in full screen - itrs weird, because when turn into windowed mode cinematics play well - in opposite when in fullscreen mode, only sound is hearable. Whats up with that??

Hello all, I've got Unz (FM Towns emulator) running under wine but its not capable of reading the original FM Towns CDROM images on my Mac. I have it working under Windows XP using Daemon Tools to mount the ISO but under OSX it does not work. I have the ISO mounted under finder and have pointed my wine configuration to the mount point. No luck. Has anyone successfully got this running under

Hi, Color of my step plot is now by default. Now I'd like to change the color as the grey scale I specified. I don't know why I got three black plot. Here I attach two version of codes. The first one produces a step plot with color by default. The second one, modified from the first one, is not producing the grey scale I want. Any help would be highly appreciated. [version 1- working]

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

So it looks like Wine is doing a good job of emulating Windows. It's so good that I'm having the same problem with old games as I was under WinXP. If I play a game with CD audio tracks, it freezes for a few seconds every time the track changes. Under Windows, I used to apply the IgnoreMCIStop fix from the Windows Application Compatibility Toolkit to fix the problem. Does Wine have

I don't know how I managed to mess up sending this last time, but somehow it got attached to the AgentCallbackLogin thread. Since the indended audience may not see it there, please indulge me by tolerating this second copy: Here's a little tidbit about the non-functional flash key on the Budgetone 100's. I have 20 of these phones. On some, the flash key works, and on some it

Hi all, I'm using Wine 20050930 on Gentoo Linux. I have successfully installed Warcraft III and got it working for the most part. I can't get the in game cinematics working. I had them working with Wine 200410??. Now all I get is a message about an invalid resolution. The movie scenes are 800x368 and I run the game at 800x600 using opengl. System specs: Toshiba Satellite 3000

I've tried Alcohol120, Clone Drive, CD Rom Emulator and daemontools but none of them work for me with Wine. Anybody knows that virtual CD program works in Wine?

I prefer to run games that require CDs from image files, since it is faster and protects the life of my CDs. In windows, I would just mount the disc image and I could then play. But using Wine and Ubuntu, it appears to work differently. When installing a Windows CD using WINE under Ubuntu 8.10 64 bit, how should I go about mounting a disc image so it is seen by games running under WINE as a CD?

I just did a gem update and it broke my rails application. I had to go back to 2.0.2, because 2.0.2.9129 produces this error on Mac OS X Leopard: /Users/nicholas/RubyDev/dummy/config/environment.rb:38: undefined method `time_zone='' for #<Rails::Configuration:0x12c9f24> (NoMethodError) from /Library/Ruby/Gems/1.8/gems/rails-2.0.2/lib/initializer.rb:47:in `run'' from

Dear all, I am developing Fortran code for general distribution, which will assist fisheries scientists in making forecasts about future fish-stock population dynamics. I have produced an S-PLUS script which takes the output from this code and generates the necessary summary plots, but I am aware that not everyone can afford to buy S-PLUS. Hence, I am interested in the use of R to produce these

I am new to Wine--I tried it about 7 or 8 years ago, with no luck whatever, and now for the first time I'm trying it again. I am amazed at how well it works! I have installed 2 windows programs, DraftSight and GcmWin. The first is a CAD program and the second produces a Great Circle Map centered on your input coordinates. I would like to try and install an old AutoCad, but I'm

Hello, We are looking to adjust the font size of the axis annotation on the graph that results from use of the metaplot() function. Metaplot seems to respond to cex and cex.lab to change those graphical parameters, but it doesn't respond to cex.axis. Is there a way to work around this by creating a customized x-axis, and if so, how? Thanks for all your help. Syntax is below. Best, Dawn
