Dear all, I am currently creating a package and writing the documention files for some functions (the main functions). When using R CMD check myPackage, I get a warning message indicating that some of my functions are not documented. How can I get rid of this problem? Of course, I don't want to document every function in the package... Thanks for your help. -- David Ardia H-building, room

Dear all, I am using the functions 'optim' and 'nlminb'. For both, you can provide a function which computes the gradient of the objective function (to enhance speed and precision). In my case, both the objective function and the gradient take time to be computed and share many common computations (similar matrix, products, etc...). Therefore, I have to compute these

Dear all, How can I pass '-Inf' and 'Inf' values from R to C code using the function '.C(...)'. When running my code, I get an error since C does not recognize -Inf and Inf values. Of course, I could use instead a very low (or high) number, but I was wondering whether a more elegant solution exists. Thanks for your help. -- David Ardia H-building, room 11-26

'AdMit' 1.00-02 is a contributed R package which provides functions to perform the fitting of an adaptive mixture of Student-t distributions to a target density through its kernel function. The mixture approximation can then be used as the importance density in importance sampling or as the candidate density in the Metropolis-Hastings algorithm to obtain quantities of interest for the

Dear all, The new version of AdMit (version 1.01-01) is now available from CRAN.

Does anyone know whether there is an R version of the S-Plus software that can be downloaded from the website of the book Elements of Statistical Learning by Hastie, Tibshirani and Friedman?

Dear all, I very often use the R function "apply", for speedup purposes. I am now also using MATLAB, and would like to use the same kind of function. I have already asked MATLAB people, and the answer is : "vectorize"... but of course, this is not always possible. So, instead of using a FOR loop all the time, I tried using the bsxfun. So you R people, who might also use MATLAB,

Dear Herman, We had the same problems over here. The problem seems to be related to Windows Hotfix KB828741. Removing the hotfix through the control panel solved it for us.

Hi, I have a problem with R, after an update: this piece of code: cat("creating resolver data frame\n"); dfG<-cbind(dfG,2^(RGN$G)) dfR<-cbind(dfR,2^(RGN$R)) suddenly, creates values to inf. Is the syntax changed for the ^ symbol in the latest R downloadable version? Kind regards, wilfred -- Dr. Ir. Wilfred Van IJcken Labmanager Genomics Erasmus Center for Biomics,

Dear colleagues, I face a problem doing haplotype analyses with haplostats: when I use the haplo.em function, the programme gives an error message because of 'recursive default argument reference.' I am not able to figure out what this means. Could you perhaps help me? The full output is the following: > library(haplo.stats) >

Dear R-users, I have output files having a variable number of tables in the following format: ------------- 1 Pietje I1 I2 Value 1 1 0.11 1 2 0.12 2 1 0.21 2 Jantje I1 I2 I3 Value 1 1 1 0.111 3 3 3 0.333 ... ------------- Would there be an easy way of turning this into (a list of) data.frames with names Pietje, Jantje and variables I1,I2,...Value? (I1,I2 are string or categorical,

Hallo, Im trying to find out how to tabulate frequencies of factors when the data have a frequency variable. e,g: i<-rep(1:5,2) j<-rep(1:2,5) N<-10*i+j table(i,j) gives a table of ones as each combination occurs only once. How does one get a table with the corresponding N's? Thanks! Gerrit. -- Gerrit Draisma Department of Public Health Erasmus MC, University Medical Center

Hi Dimtris and esteemed useRs, I don't understand why i get this error message when attempting to use merge() - > temp <- merge(x, y[,17, drop=FALSE], by=rownames, sort=FALSE) Error in as.vector(x, mode) : cannot coerce type 'closure' to vector of type 'any' It should work because: > all(rownames(x[order(rownames(x)),]) == + rownames(y[order(rownames(y[,17,

Dear all, sorry to bother you with potentially known issue -- we have noticed that if we select data frame rows by rownames, we get some results back if the match can be done unambiguously, though the match is not perfect (see example), e.g. x{"2",] will return a row if there is a unique row with name starting with "2" (but may be "2375745"!) is that a

Dear All, We are happy to announce the release of the new version of DEoptim (version 2.0-0) which is now available from CRAN. The DEoptim package [3] performs Differential Evolution (DE) minimization, a genetic algorithm-based optimization technique [2,3]. This allows robust minimization over a continuous (bounded or not) domain. The new DEoptim function calls a C implementation of the DE

Dear helpers, I am a Dutch student from the Erasmus University. For my Bachelor thesis I have written a script in R using boosting by means of classification and regression trees. This script uses the function the predefined function rpart. My input file consists of about 4000 vectors each having 2210 dimensions. In the third iteration R complains of a lack of memory, although in each iteration

Esteemed UseRs and DevelopeRs, Just coming to terms with the very attractive proportional venn gernator, venneuler(), but would like to customize a few things. Is it possible to- -suppress all circle labels? -suppress only certain circle labels? -print specific text strings at specified locations within the circles? and unions? -specify circle colors? -specify label font, size & color?

Esteemed UseRs, This must be embarrassingly trivial to achieve with e.g., melt() and cast(): deduplicating records ("pw.X" in example) for a given set of responses ("cond.Y" in example). Hopefully the runnable example shows clearly what i have and what i'm trying to convert it to. But i'm just not getting it, ?cast that is! So i'd really appreciate some ones
