Hello, I am trying to get the output from the numerical simulation of a system of ordinary differential equations for a range of values for three parameters. I am using the ode() function (deSolve package) to run the numerical simulation and apply() to run the simulation function for each set of parameter values. I am having trouble getting the apply() function to work. Here is an

I've been a Linux user for a few years now but this is my first taste of Wine. Naturally, I've got a problem (leave it alone!). A transcript of my wine session looks like this: # wine --winver win95 /mnt/cdrom/railatlas.exe FIXME:pthread_rwlock_rdlock FIXME:pthread_rwlock_unlock Could not stat /mnt/fd0 (No such file or directory), ignoring drive A: FIXME:pthread_rwlock_rdlock

Hi, Given that R reports Type I sums of squares, isn't it a bit anachronistic that it re-orders terms in formulae? > d <- expand.grid(y=rnorm(8), + A=factor(c(1,2)), + B=factor(c(1,2)), + C=factor(c(1,2))) > summary(aov(y ~ A+B+A:B+C,data=d)) Df Sum Sq Mean Sq F value Pr(>F) A 1 8.294e-34 8.294e-34 1.027e-33 1

I have a statistical problem which has given me no end of grief recently, and am posting here in the hope that somebody can give me a straight answer. I'm a IT postgrad, not a statistician, so people may have to speak really slowly and clearly for me to get it :) I am collecting simulation data, and the results are geometrically distributed (or approximately so). From what I can gather

All, I have been working on a component that is included with samba called SMBSH. The binary allows you to automount your NT shares by accessing your profile . I have been working on this for the last few days and have been unsuccesful at getting it work. Now I am not much of a programmer, but I did my best to try and troubleshoot this. However it just does not want to work in Linux. I

Hi all , I set up https on CentOS 4.4. I did the below sets of commands, first removed existing files rm /etc/httpd/conf/ssl.key /server.key rm /etc/httpd/conf/ssl.crt/server.crt Next, I created key. Change to the /usr/share/ssl/certs/ directory and type in the following command: make genkey then issued below command, make testcert finaly /sbin/service httpd restart Then I got the

I have 20 variables: 5,9,6,1,5,9,7,4,5,6,3,2,4,8,9,6,1,8,4,8 How do I calculate the corresponding quantiles from a normal distribution with the same mean and variance as the sample? Also, how do I draw a QQ plot of the data?

But It gives the below error. why is that ? -- [root at worldnet ~]# mount /dev/hdc /media/cdrom/ /dev/hdc: Input/output error mount: block device /dev/hdc is write-protected, mounting read-only /dev/hdc: Input/output error mount: /dev/hdc: can't read superblock [root at worldnet ~]# Thank you Indunil Jayasooriya -- Thank

Hello, after searching through the archives and not finding a thread that answers this question, I thought I'd pass it on to the list. Given a data frame and given a factor variable that assigns a class to each case in the data frame, what is the most efficient way to sample a given number of cases from each class? I've found a roundabout solution that works as follows: for each class:

Hi, I get the below error, while starting clamd. what's wrong with it? help is needeed.

On the cover of Zivot and Wang's Modeling Financial Time Series with S Plus, there is a correlation plot that seems to indicate the strength of correlation with color-coded squares, so that more highly correlated stocks appear darker red. If anybody out there is familiar with the book or understands what I am talking about, I am curious as to whether or not there is a similar function in R

Hello, Is anyone else having trouble with the and_raise method on mocks, with respect to shared behaviors? If I do the following instead: foo.should_receive(:bar).and_return { raise } everything seems to work. I have been supplying no arguments to and_raise, by the way. Also, you may want to make the background in the code examples on the home page a little lighter. I am hardly able to

Hi R people: On page 235 of the Blue Book (Becker, Chambers, and Wilks), there is a "compose2" function. compose2 <- function(f,g) { gg <- substitute(g1(x)) print(gg) gg[[1]] <- g ff <- substitute(f1(y)) print(ff) ff[[1]] <- f ff[[2]] <- gg print(ff) fun <- function(x){ NULL } fun[[2]] <- ff fun } However, when I run this function using sum

Hi all. I would be very pleased if someone could help me, as I do not seem to get the different branches of my tree painted in different colours. The closest I get is colouring the names of my samples(=names of the branches). Here is the code. data <- read.table(file = "S://SEDIM//TRFLP//B12.5_50-700bp.txt" , as.is = TRUE, header = TRUE, sep = "\t", row.names =

R version 2.7.0 RC (2008-04-20 r45403) When using semi-transparent filled plotting symbols, the border of the symbol has a different (darker) colour than the interior: plot(0, 0, pch=19, col="#FF000022") (Saving this as a PDF and looking at it magnified may make it easier to see.) This is pretty annoying, since when plotting partially overlapping points, the border colour dominates,

I've been trying to get RedAlert working under wine for about a month now. I start wine from an xterm with: $ wine /WIN95/westwood/redalert/ra95.exe 2>&1 | tee wine.out ; and get the following in wine.out: fixme:ddeml:DdeConnect (0x1,49161,49163,(nil)): stub fixme:ddeml:DdeNameService (1,49161,0,1): stub fixme:dsound:IDirectSoundImpl_SetCooperativeLevel (0x403ce3e4,00000138,2):stub

In an R graphic, I'm using cond.col <- c("green", "yellow", "red") to represent a quantitative variable, where green means 'OK', yellow represents 'warning' and red represents 'danger'. Using these particular color names, in B/W, red is darkest and yellow is lightest. I'd like to find color designations to replace yellow and

Thanks very much Douglas for the pointer to nlm. Maybe the "Notes on R" maintainer can add at least a mention of nlm in the section on nonlinear fitting? I never did nonlinear fitting in S-Plus before, so I have nothing to unlearn, but I was hoping someone could show me how to do a least squares fit with nlm. example: x<-c(1,2,3,4,5,6) y<-.3*x^-.6 +.2 y<-y+rnorm(6,0,.01)
