Hello, everyone! I picked up R several months ago and have adopted it as my choice for statistical programming. Coming from a Java background, I can honestly say that R is not only free, it is better tha S-plus: the lexical scope in R makes it very simple to simulate Java's object model. For this, I encourage everyone to read the artcle: Robert Gentleman and Ross Ihaka (2000) "Lexical

To be fair I don't really understand what the error is telling me so I don't know how to correct it. I'm trying to reshape my data so that I do repeated measures ANOVA on it. The warning message: "Error in d[, timevar] <- times[1L] : subscript out of bounds" The program: library(QRMlib) library(Hmisc) ss<-5 mu<- c(0,2,3,12) mu2<- c(0,2,10,20)

Hi everyone, I have posted a similar question to this list, but I don't get a reply. I really want to solve this problem, so I post it again... I am trying to use R to fit some mixed-effects models for a nested data. The data is a simulated data with 111 subjects. Each subject has 6 waves' data. Below are the first two subjects' data : > simu1[1:12,] Grouped Data: gf ~ age |

Hi, Sorry to bother those who are not interested in the question. I am using R to run a multiphase mixed-effects model. I simulated a data set by using the following model. And now I want to use R to estimate the parameters and compare the results with the true values. The equations of the models are as below: gf[ij]=b0[i]+b1[i]*age[ij]+b2[i]*max(0,(age[ij]-tau[i]))+e[ij] b0[i]=b00+e[i0]

Hi, I am using Splus to run a multiphase mixed-effects model. The quations of the models are as below: gf[ij]=b0[i]+b1[i]*age[ij]+b2[i]*max(0,(age[ij]-tau[i]))^2+e[ij] b0[i]=b00+e[i0] b1[i]=b10+e[i1] b2[i]=b20+e[i2] tau[i]=tau+e[i3] i: 1,2,...,100 subjects j: 1,2,...,6 occasions The main scripts of Splus is: simu1<-groupedData(gf~age|id) simu.nlme<-nlme(gf~(b0 + b1 * age + b2 *

I set up a simple BlindUp and BlindDown div that works seamlessy in Firefox but doesn''t work as smoothly in IE. When blinding down, the whole div flashes and then Blinds down. The same thing when blinding up. Is this something that is fixable? _______________________________________________ Rails-spinoffs mailing list Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org

Hi All, I a C function code, which has been successed in integrating with Splus on Unix. Now I want to move it on windows. So I want to integrate this C function with R on windows XP. I download tools.zip and saved it in c:\bin directory, download MinGW and saved it in c:\MinGw directory, download Perl and saved it in c:\Perl directory. My path is set as:

Does anybody have any suggestions on how I might simulate from fitted GAM model? I am using the gam function in the mgcv package to fit a variable coefficient model like the following from the examples. I would like simulate based on the fitted model like the simulate function in the stats package does for lm models. library(mgcv) set.seed(10) ## simulate date from y = f(x2)*x1 + error dat

Dear R-listers, I am writing a function that will generate a simple plot for the user . The size of the window (that contains the plot) may not be what the user wants. Supposing the user adjusts the window to a size of her/his choice, I would like to be able to save the new window size and specify the plot to be of this new window size when the user calls my function again. My question is

Railers, I am running an application on Rails 2.3.2. For some reason within our organization, we wish to remain on this version of Rails. For BDD/Testing, we use Cucumber. So I installed Cucumber (0.8.5), Capybara (0.3.9) and Selenium-webdriver (0.0.17). But when I run Cucumber on any feature, I get an error saying *" wrong number of arguments (2 for 1) (ArgumentError)"*, (Check here

Hi all, I have written a program which performs some data simulation, model fitting (to the simulated data) and then it will save the parameter estimates from each loop into a matrix for later use. Because convergence will not be met in some sets of the simulated data, I have used a 'while' instead of a 'for' loop for the job. With a 'for' loop I was not able to turn

Hi all, I want to show the rows of a matrix (100x3) of which some of its elements satisfy a certain condition. In particular, how can I display the 2 rows of my matrix one after the other and not all all elements of column 1 first, then column 2 and so on. See the following. > finest[finest[,1] > 10^3] [1] 4.960632e+13 3.612619e+04 7.668204e+12 1.001911e+04 8.886153e-01 [6]

Hello all, I am still very new to programming and wonder if I could get some help. I have tried to figure this out myself but still having trouble with some of the concepts. I’ll do my best to explain the problem and include the code. I may be completely off track, so ANY direction offered would be deeply appreciated. I have a question model / object which consists of a question, answers, and

I am checking a file system (ext3) as shown below. It is actually a fresh file system, as I had deleted all partitions and created an ext3 file system. But when I run the check with the verbose option, it says I have one large file. Am I missing something here, or is it odd that I cannot find this large file it is reporting? I reviewed some documentation on ext3 file systems, and experimented

Hi guys, I have written a rails plugin/gem to generate css sprite image automatically. The project repository is here: http://github.com/flyerhzm/css_sprite It is based on RMagick and you need only define a rule from what source images to a destination image, as follows: forum_icon_vertical.gif: # destination image file sources: # source image file list - good_topic.gif

Anyone using the rrdgraph report on the puppetmaster on Debian stable? I''m trying to get this working and not getting far. I even took rrdtool and librrd0-dev from backports and I still get the same problem. It seems that the rrdfiles are being somewhat created, but nevertheless, the puppetmaster isn''t happy and keeps spewing: err: Report rrdgraph failed: Could not create

Dear all, I am doing 200 times simulation. For each time, I generate a matrix and define some function on this matrix to get a 6 dimension vector as my results. As the loop should be slow, I generate 200 matrice first, and save them into a list named ma, then I define zz<-sapply(ma, myfunction) To my surprise, It almost costs me the same time to get my results if I directly use a loop
