Hello... I would like to use R for 'pipelining' data among several programs. I'm wondering how I can use R to call another program, feed that program a set of parameters, and retrieve the output. E.g., I have an executable that, when opened, prompts the user to enter a set of parameters. The program then executes & prompts the user for the name of an output file. I need to

Hello. I am creating an R package that I'd like to submit to CRAN (OS Windows XP). How do I distinguish among 'public' functions, e.g., those that are intended to be called by users of the package and for which I am providing documentation & examples, and 'private' functions, which are used internally by the 'public' functions, but for which I do not wish to

Hi.... I am assembling an R package (under Windows XP, R v.2.3) and have a very basic question. Running R CMD build does not generate a pdf. R CMD check generates a .dvi, but I cannot figure out how to automatically create the pdf. I thought from reading the "writing r extensions' manual that R CMD build was supposed to generate the pdf. I am having no success using various

Hi I have a question about the creation of variables within lists in R. I am running simulations and am interested in two parameters, ESM and ESMM (the similarity of these names is important for my question). I do simulations to generate ESMM, then plug these values into a second simulation function to get ESM: x <- list() for (i in 1:nsimulations) { x$ESMM[i] <- do_simulation1()

Hello... Is it possible to use "density" or another kernel density estimator to identify the mode of a distribution? When I use 'density', the resulting density plot of my data is much cleaner than the original noisy histogram, and I can clearly see the signal that I am interested in. E.g., suppose my data is actually drawn from two or more normal (or other)

This might be of interest: http://math.usu.edu/~minnotte/research/software/modetree.r (I was not able to get to the link, but google has a cached version.) Prof. Marron's SiZer maps may also be of interest, but AFAIK the code is in Matlab only.

Hello - I am having a problem with the function 'integrate'. I am running R on OSX (R 2.5.1). I am trying to suppress the error message when 'integrate' attempts to integrate across a parameter set giving a non-finite function value. I'm using it in a MCMC / simulated annealing algorithm, and it is entirely possible that some parameter sets will give non-

Hi - I also posted this on r-sig-ecology to little fanfare, so I'm trying here. I've recently hit an apparent R issue that I cannot resolve (or understand, actually). I am using the quantreg package (quantile regression) to fit a vector of quantiles to a dataset, approx 200-400 observations. To accommodate some autocorrelation issues, I have to assess significance with
