Dear R users, I would like to calculate a cumulative sum as following: on the i-th row, in the j-th column of a matrix, I would like to obtain the sum of the (i-1) preceding elements of this j-th column. Could I avoid a "for" loop? Thank you, Tristan Lorino ---------------------- ?cole Nationale V?t?rinaire d'Alfort - http://www.vet-alfort.fr, T?l. 01 43 96 70 33 M?l. tlorino at

Dear R-gurus, I have an interpretation problem regarding lme models. I am currently working on dog locomotion, particularly on some variation factors. I try to figure out which limb out of 2 generated more dispersed data. I record a value called Peak, around 20 times for each limb with a record. I repeat the records during a single day, and on several days. I tried to build two models, one

Hi, About GUI and R, I would say that personnaly, I need to build a nice GUI for people who does not know anything about R, to conduct simulations. I don't know if the choice of R is the best. Maybe writing all the code in Java would be better... I don't know. That's why I have tried to install RSJava from Omegahat on my computer (Windows 2000). With R 1.5.0 or 1.5.1, I get the

Hi, I would create a function rdiscrete that returns the value of a discrete random variable X defined on a subset which can change, and for the same probability for the issue, eg: X could sometimes take a value in the subset {2,3,4} with probability 1/3 for each issue, and sometimes X could take a value in the subset {2,3,4,5,6} with probability 1/5 for each issue, etc. The function should have

Hello, I am using function lmodel2 to calculate RMA regression between life-history traits in ladybirds beetles. It works well but I am not able to plot an RMA regression line on the scatterplot of my data. I am of course unable to plot the confidence intervals. For ordinary least square regression abline(lm(x~y))works well but for RMA regression, abline(lmodel2(x~y))does not do it. If somebody

Hi, See below I reply your message for <https://stat.ethz.ch/pipermail/r-help/2008-April/160966.html>[R] predict.glm & newdata posted on Fri Apr 4 21:02:24 CEST 2008 You say it ##works fine but it does not: if you look at the length of yhat2, you will find 100 and not 200 as expected. In fact predict(reg1, data=x2) gives the same results as predict(reg1). So I am still looking for

hi everybody I have to do a lot of Anova with R and I would like to have another type of coefficients coding.. I explain. by default if I have 2 temperatures for an experience. 100°C or 130°C and I want to see the temperature effect on the presure I want to estimate the coefficient of each temperature. I will obtain ,with the anova, juste one coefficients for example +3,56 (for 100°C), and the

Dear all, I am looking at habituation of dogs trotting on a treadmill. I record the ground reaction force and I analyze it with several discrete variables (maximum, minimum,...) For each variable, I get between 40 and 50 data per sample. I record data at time 1 min, 2 min, and 4 min a day, and I have 4 days of measurement (one day a week). That means I have 12 samples : Day1_Min1, Day1_Min2,

Dear all, I try to compare the performances of several parameters to diagnose lameness in dogs. I have several ROC curves from the same dataset. I plotted the ROC curves and calculated AUC with the ROCR package. I would like to compare the AUC. I used the following program I found on R-help archives : From: Bernardo Rangel Tura Date: Thu 16 Dec 2004 - 07:30:37 EST

I might be missing something but I thought that AUC was a measure for comparing ROC curves, so there is nothing else needed to "compare" them. The larger AUC is the higher correlation of 2 variables compared. No other measures or calculations are needed.

First of all, I apologize for the triple post, but I did not see that the word wrap on the r-help list site would render my code unusable. So here it is again. Hoping that this time it will work if you cut and paste it in your Rgui. I have a program that works well in Rgui but that does not work in a batch file (Execution halted). Here's the code (it will work on your R, but you need
