I suppose everybody who makes a package for the first time thinks "I can change anything!" and then runs into this same question. Has anybody written out information on how a package can override functions in R base in the R 2.14 (mandatory NAMESPACE era)? Suppose I want to alphabetize variables in a summary.data.frame, or return the standard deviation with the mean in summary output.

I thought R users might be interested (surprised) to hear that R will have some competition on Linux now.

Greetings. I've written a convenience function for multicollinearity diagnosis. I'd like to report to the user the formula that is used in a regression. I get output like this: > mcDiagnose(m1) [1] "The following auxiliary models are being estimated and returned in a list:" [1] "`x1` ~ ." formula(fmla)() [1] "`x2` ~ ." I'd like to fill in the period

Kurt, if you really want to find out what things an S help file can contain, you must learn some nroff/troff [ maybe use 'groff', the GNU one ]. As always, ultimate documentation is == source. The definition of the S help is in the two files $SPLUS/cmd/help.[nt]r where nr ^= nroff, i.e. ASCII output tr ^= troff i.e. printed output (e.g via Postscript conversion) help.tr

Some people here have started using CASIM, which is an add-on we got a while back for S-Plus that allows one to spawn an S-Plus process from a C program and communicate with it. How hard do folks think it would be to develop such an interface for R? I might try it, but I'm not completely sure I'm up to it (although it would exercise my programming skills). Also, I wonder again at the

Hi, I'm trying to use the library mclust for gaussian mixture on a numeric vector. The function Mclust(data,G=3) is working fine but the fitting is not optimal and is using modelNames="E". When I'm trying Mclust(data,G=3,modelName="V") I have the following message: Error in if (Sumry$G > 1) ans[c(orderedNames, "z")] else ans[orderedNames] : argument is

The R Journal home page doesn't make any promises about how frequently the journal will be published. Historically, though, there have been issues in June and December of each year. The June issue has always appeared by this time (6 August) in previous years. Has there been a change in the publication schedule? Are there still plans for a June 2016 issue? Thanks Gordon

Dear all, I'm writing to ask for advice as to best practice. A PhD student working with me is writing C++ code that we hope to make public as src code in our Bioconductor package edgeR. He wants to call the function fmm_spline, which is part of the source code for the stats package http://svn.r-project.org/R/trunk/src/library/stats/src/splines.c, from his C++ code. This function

Hello, I have been trying to get an ANOVA table for a linear model containing a single nested factor, two fixed factors and a covariate: carbonmean<-lm(C.Mean~ Mean.richness + Diversity + Zoop + Diversity/Phyto + Zoop*Diversity/Phyto) where, Mean.richness is a covariate, Zoop is a categorical variable (the species), Diversity is a categorical variable (Low or High), and Phyto (community

Hi all, I am a real novice to R. :) I am struggling with a problem for generating colored dendrogram. I have searched the R list and complied/collected a R code which can generated a colored dendrogram based on the rainbow color and 4x4 similarity matrix (say matrix:m). In this dendrogram, each leaf is colored differently. But, I do not want the leaf colored on a random basis. I want to assign

Perhaps I've missed this in the FAQ, but has someone documented any tricks which can be used in R to optimize memory usage/execution time? For S+, StatSci used to recommend: 1. Avoid "for" loops whenever possible. 2. In "for" loops, have a simple expression, such as TRUE, as the last statement. 3. Allocate memory for a vector/array at one time, rather than building it up

First, let me say how glad I am to discover R! As a former user of S at the University of Toronto and, briefly S-Plus from StatSci (I had a binary version of that on Slolaris for a while), I was really glad to find the "R" project. This is perhaps not your bug, but I did have one minor glitch in compiling R. OpenBSD 2.8's math.h does not export the "struct exception"

Martin Maechler has suggested that I post this comment to r-devel. It was originally posted to bioconductor. --------------------------------- I'd like to raise the issue of a capitalization convention for naming objects in R. Almost everything in R used to be lowercase but recently there is increasing use of mixed upper/lower case to define names. There is potential for using the

This is just a suggestion/wish that it would be nice for the F-distribution functions to recognize limiting cases for infinite degrees of freedom, as the t-distribution functions already do. The t-distribution functions recognize that df=Inf is equivalent to the standard normal distribution: > pt(1,df=Inf) [1] 0.8413447 > pnorm(1) [1] 0.8413447 On the other hand, pf() will accept Inf
