Dear All, Ulric Lund and me are developing a new package called 'circular' that as soon as possible will substitute 'CircStats' package. A pre-released is available at: http://www.dst.unive.it/~claudio/R/circular_0.1.tar.gz I kindly ask everybody is using CircStats to check this new package and send me comments, suggestions and bugs to claudio at unive.it and not to the list. As

Dear all, I am facing a problem with running a script that i have written in R and i hope you can help me spot which exactly is the problem and how i can solve it. The error I get is the following: ---- Error in .jcheck(silent = FALSE) : Java Exception <no description because toString() failed>.jcall(row[[ir]], "Lorg/apache/poi/ss/usermodel/Cell;", "createCell",

I saw different specifications for Random Effects and I'm confused about the use of "/" and the use of "(0+...|)" . Let say we have a nested structure where some countries have some several plants in different states and we measure the reaction to a drug. The list of Countries = USA, France, Italy The States for USA = Michigan, Florida, California The States for France

Dear all, I have installed R on Linux/Ubuntu 8.04. When I try to load the tcltk package, I get the response: > library(tcltk) Error in firstlib(which.lib.loc, package) : Tcl/Tk support is not available on this system Error in library(tcltk) : . First.lib failed for 'tcltk' In order to solve this problem, I try to: 1. To download the tcl and the tk packages (version: 8.5) from

Hi, I'm trying to debug a function I wrote to calculate the cindex for a hierarchical tree. For this it is useful to compare my calculations with those in output from the clustindex function, in the cclust library. There's no way, however, to have the cindex value for a given output of the cclust function, as a NA value is always returned. This happens almost surely because the cindex in

Dear all, I would like to ask information about the package mvtnorm in R. It is very useful for me the "qmvnorm" comand, but I see that it can compute only quantile for equicoordinate. Is it possible to have a curve (or a set of values) if we don't want equicoordinates? Thank you Best regards Antonio. -- Antonio Lucadamo, Dipartimento di Scienze Economiche e Metodi Quantitativi

Dear all, I'm using the ellipse package and I would like to verify if the confidence region that I build with this package can be equivalent to an Union Intersection Test. I used different value for the t-statistic but I can not find the right equivalence. Does someone know how to choose the right value? Thanks a lot.

Dear R-users, I'm working with the Rpart package and trying to understand how the procedure select the best split in the case the method "class" and the splitting index "Gini" are used. In particular I'd like to have look to the source code that works out the best split for un unordered predictor. Does anyone can suggest me which functions in the sources I should

Dear ALL, I'm trying to figure out what the percentage effects are in a logistic regression. To be more clear, I'm not interested in the effect on y of a 1-unit increase in x, but on the percentage effect on y of a 1% increase in x (in economics this is also often called an "elasticity"). For example, if my independent variables are in logs, the betas can be directly

Dear All, I'm trying to use waldtest to test poolability (parameter stability) between two logistic regressions. Because I need to use robust standard errors (using sandwich), I cannot use anova. anova has no problems running the test, but waldtest does, indipendently of specifying vcov or not. waldtest does not appear to see that my models are nested. H0 in my case is the the vector of

Dear all, I'm trying to manage with user defined split function in rpart (file rpart\tests\usersplits.R in http://cran.r-project.org/src/contrib/rpart_3.1-34.tar.gz - see bottom of the email). Suppose to have the following data.frame (note that x's values are already sorted) > D y x 1 7 0.428 2 3 0.876 3 1 1.467 4 6 1.492 5 3 1.703 6 4 2.406 7 8 2.628 8 6 2.879 9 5 3.025 10 3 3.494

Hi All, I would like to introduce intrinsics to generate efficient codes for 'absolute differences', 'horizontal add' and 'sum of absolute differences' Idioms used by user programs. Identifying these idioms at lower level (Codegen) is complex. These idioms can be identified in LV/SLP and vectorized using above intrinsics to generate better code. Proposal: 1. Add

Dear R-helpers, I have a problem with the tcl "after" instruction. When I send: > library(tcltk) Loading Tcl/Tk interface ... done > tcl("after",1000,cat("try tcl after\n")) try tcl after <Tcl> the tcl command works fine. Similarly, the tcl command: > tcl("after",1000,plot(rnorm(100))) <Tcl> works fine. But, if I send the command:

Hello, I would like to place region names (or abbreviations if space is too limited) on a map. I have tried the following, copying and adapting various examples I have seen but without success. The first example is self-contained, but the second one requires the .shp file, which can retrieved at http://www.gadm.org/country. ----- Example 1 ----- library(sp) con <-

Dear All, I'm looking to perform an ANOVA between two nested panel fixed effects models. I tried with anova, as well as with waldtest. anova tells me there is no method available for plm objects, while waldtest tells me my models are not nested. I think they are instead. The difference between the two models is that in the second I let the regression coefficients of a given variable variate

Dear all, a question about the package boot: is it possible to bootstrap a function of arguments of different length? is there an alternative package? below an example of a simple try, many thanks paolo > library(boot) > blue<-c(4, 3, 4, 1, 2, 3, 1) > red<-c(4, 3, 4, 1, 2, 3, 1, 2, 3, 1, 3, 2) > > test1<-function(x,y,d){ + return(sum(x) - sum(y)) + } > b=boot(red

Dear R users, I'm using the rpart package to build classification trees. I'm interested in implementing the ordered Twoing as a splitting criterion. Does anyone have experience with this task ?
