Dear Everyone, I wrote a Taylor diagram program in R, but it was not very general, so I was happy to find the Taylor.diagram in the plotrix package. On the other hand I can find many problems with the pos.cor=TRUE case, in other words, when we use only the first quarter of the space (positive correlations). (When we choose pos.cor=FALSE, the program seems to me perfect) 1.There is only one line

Dear Everyone, I 've just begun to use the library ncdf and I would like to compare meteorological observational data with forecast data, so to make verification. The netcdf files I'm using contain data of many different parameters in many different stations. I could read easily that I needed, but naturally I do not need the data of all the stations. On the other hand, the order of

Hi All, I want to make a 1 dimension vector from the first two dimensions of a 3 dimension array, so make a 2 dimension vector from a 3-dimension one, with "fusing" (making as.vector) the first two dimensions. It seems to be very easy, but I cannot find the solution, I mean it would very strange, that I would do taking the single 1 dimensional vectors from the 3 dimensional one, make one

Ma premi??re question: puis-je ??crire en fran??ais, mon anglais est pire que pire. J'essaie en fran??ais; sinon, j'essaierai une traduction! Je sduis d??butant. Ma question est donc simple, j'imagine. Je travaille sur des tableaux de statistiques. Je prends un exemple: J'ai un "frame" que j'appelle "eurostat" qui me donne des statistiques

Dear List, I am trying to solve a problem: I have approximately 100 Excel spreadsheets each with approximately 4 sheet each that I would like to download and import in R for analysis. Unfortunately i realized (i also sent an email to the author or xlsReadWrite() ) that the read.xls() doesn't allow to import the file in R from internet. Here it is the the code:

I am working on a rails app to serve as the admin app for an existing java webapp. For this reason, I am constrained by the current database structure, which does not by any means conform to the ideal rails defaults. Anyway, I have the following models: class Provider... belongs_to: login class Login... has_and_belongs_to_many :demographics class Demograpics... ... Everyone has a

Hi all, I am using aidsEst( ) in "micEconAids" package to estimate Demand system. But I would like to add more demographic variables in demand system. How can I add those information? for example: mydata<-data.frame(p1,p2,p3,p4, s1,s2,s3,s4, totalexp,

Hello R users, I am relatively new to the R program, and I hope some of you can offer me some suggestions on how to organize my data in R using some of the more advanced data structuring technique. Here's my scenario: I have date set of 50 participants (each with conditions and demographic data), each participant performed 2x16 trials, for each trial, there was specific information about the

Hi colleages! I want to import data from ms-excel and other spreadsheet formats (lotus, etc). Does exist any way to do it within R? The main problem is that many spreadsheet data use comma as decimal separator and not the point as needed in R (and many software for Linux), so importing data first as a tab separated values does not solve this problem. Thanks, Tom?s Revilla

In Germany the Unemployment Agency uses a sectioning of the german map that is different from the usual Administrative Boundaries. Some demographic data are available in Administrative Boundaries only, some in Unemployment Boundaries only. I would like to generate estimates in one boundary system of data availabe in the other boundary system, and would appreciate advice concerning the following

Hi, I need to derive a time series that represents the first derivative of an original time series. The function coefDeriv in the cyclones package seemed to be the ticket, but I'm not sure if I am interpreting the output of the function correctly...or even using the function correctly. This is a snipbit of what I've been trying: -------- library(cyclones) ## read in my 1-column of

Dear All: I have a clinical study where I would like to compare the demographic information for 2 samples in a study. The demographics include both categorical and continuous variables. I would like to be able to say whether the demographics are significantly different or not. The majority of papers that I have read use multiple techniques to achieve this (e.g., t-test for the continuous

Dear R-friends, I use optim(par=c(mystartingpoints), fn=myloglikelihoodfunction, gr=NULL, method=c("L-BFGS-B"), ## I would like to do not use any bounds control=list(trace=6, ## just to see what it's going on maxit=c(20000)), ## to be sure the it doesn't stop reaching the max iterations

Dear R-users, I am going to try to be as clearer as possible, showing also an example. 1) I have a function (in my real case it's much more complex) 2) I use "optim" to minimize 3) I want to use as method L-BFGS-B for several reasons 4) I know I could use "trace=6" (in "control") in order to see "live" the procedure 5) I would like to see separately the

Dear R-users, within the rgl-package, I would have a question about the usage of persp3d in combination of rgl.viewpoint. I am not able to figure out how to let a 3D plot rotating around likewise the example in ?rgl.viewpoint. It seems that when I use persp3d(...) I see something on my screen, which is different from what I get when it's rotating. Is there any different behavior between

Hi Experts, I am new to R, using decision tree model for getting segmentation rules. A) Using behavioural data (attributes defining customer behaviour, ( example balances, number of accounts etc.) 1. Clustering: Cluster behavioural data to suitable number of clusters 2. Decision Tree: Using rpart classification tree for generating rules for segmentation using cluster number(cluster id) as target

Dear R-users, I would like to place two 3D plots side-by-side in a rgl-setting. It would nice to have something like "par(mfrow=c(1,2))" for basic plots, or an array framework for wireframe(lattice) (see example below). I only managed to overlap two persp3d plots. My final idea would be to animate both surfaces using play3d(rgl). Thanks in advance for any help. Best, Carlo Giovanni
