similar to: Rprofile: distinguish between Rgui, Rterm, JGR?

[Environment: Win XP, R 2.10.1] I'm trying to install the packages JGR and iWidgets required by the extracat package to make the interactive plots in the package work. I've tried various things, but nothing seems to work. Here is my most recent attempt, followed by my sessionInfo(). Does anyone have any suggestions how to make this work? > > library(extracat) Loading

[Env: Win XP, R 2.14.2, R 2.15.0] I have a replacement function for setwd() in my .Rprofile which displays the current R path in the R window title. It no longer works in R 2.15.x, giving the error below. Worse, the error prevents the rest of my .Rprofile script from completing. Is there some way to rescue this, i.e., preserve this behavior in R 2.15? If not, how can I modify my script so it

I 'source' the file into an environment and then attach the environment to keep the global from being clustered: # read my functions into a environment .my.env <- new.env() sys.source('c:/perf/bin/perfmon.r',

[Env: WinXp, R 2.9.2] In my .Rprofile, I define a number of utility functions I'd like to have available in my R session, but don't want them to be *normally* listed by ls(), or more importantly, saved if I save my session variables/functions.

In my .Rprofile I have the following functions which display the current directory in the main R window title bar, and modify base::setwd() to keep this up to date. I like this because I can always tell where I am in the file system. cd <- function(dir) { base::setwd(dir) utils::setWindowTitle( short.path(base::getwd()) ) } short.path <- function(dir, len=2) { np

kronecker, with make.dimnames=TRUE uses a hardwired sep=":" in the line tmp <- outer(dnx[[i]], dny[[i]], FUN = "paste", sep = ":") For an application in which dimnames arise from an n-way array, where different dimensions have different roles, and I would like to be able to use kronecker in the form kronecker(A, B, make.dimnames=TRUE,

I'm looking for an R equivalent of Beaton's (1964) Sweep algorithim for partial inversion of a matrix by pivoting. It implemented in SAS/IML as sweep(matrix, indices), described here http://support.sas.com/documentation/cdl/en/imlug/59656/HTML/default/langref_sect266.htm and here for python http://adorio-research.org/wordpress/?p=262 -- Michael Friendly Email: friendly AT yorku

Under Windows (and maybe others) you can use file.choose() as a substitute for an explicit file= argument in most places. Is there an analog for what I'll call dir.choose(), so that I can say setwd(dir.choose()) thx, -Michael -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept.

A simple question, but I can't find something to do what I want: Given: a vector of numbers, like lambda <- c(0, 0.005, 0.01, 0.02, 0.04, 0.08) Desired: format them in minimal space for use as plot labels, ie, without leading or tailing 0s. For this example: lambdaf <- c("0", .005", ".01", ".02", ".04", ".08") -- Michael

Using R 2.13.1, I am now getting the following NOTE when I run R CMD check on my HistData package * checking for unstated dependencies in examples ... NOTE 'library' or 'require' calls not declared from: gplots sp Under R 2.12.x, I didn't get these notes. I have ~ 25 .Rd files in this package, and AFAICS, every example uses library or require for the functions used;

the NEWS file for R-devel says * Even data-only packages without *R* code need a namespace and so may need to be installed under *R* 2.14.0 or later. but what should this contain? Can it simply be an empty NAMESPACE file? I assume that data does not have to be exported. -Michael -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept. York University

I want to generate multiple multivariate normal samples with different mean vectors and common covariance matrix. I can do this with a loop, but can't quite figure out how to do it with apply and friends. In the example below, I want values to have 3 columns: group, x, y # number of groups, and group means x <- jitter(seq(2,10,by=2)) y <- x + rnorm(length(x), 0, .5) means <-

A minor gripe/request: Could all R CMD package tools not at the very least be consistent in indicating when they are done, as in * DONE (packagename) or at least * DONE R CMD build leaves one hanging, not knowing whether it has completed or it is time to get another coffee. * checking for file 'C:/Documents/workspace/heplots/DESCRIPTION' ... OK * preparing 'heplots': *

It is A Good Thing to regularize Authors and Maintainers of packages, particularly for citation() and toBibTex(). Could I add a suggested TODO item for the maintainer of package.skeleton and friends to help reinforce this for new packages: - Please add appropriate templates for Author at R in the skeleton DESCRIPTION file generated, indicating the proper format as well as the use of role= to

I want to use something like printCoefmat() in a print.summary method to print a more nicely formatted version of the result from a summary method, but where the estimates may be cross-classified by one or more factors. However, printCoefmat() assumes that the labels for the parameters are the rownames of the object, and prints factors as integers. With one factor, I could just assign that as

Aficionados of graphics may be interested to know that the English translation (1984) of Jacques Bertin's Semiology of Graphics has been reprinted by ESRI. http://www.amazon.com/Semiology-Graphics-Diagrams-Networks-Maps/dp/0299090604 new edition: http://www.amazon.com/Semiology-Graphics-Diagrams-Networks-Maps/dp/1589482611/ref=tmm_hrd_title_0 The long out-of-print 1984 edition sells for

In http://finzi.psych.upenn.edu/R/Rhelp02a/archive/14637.html some rudimentary R functions were given for drawing proportional area venn diagrams with area of each intersection ~ the count in a 2 x 2 x 2 table. I'm interested in this, for another application: showing the correlations among Y, X1, X2 using area ~ r^2 of each pair (sometimes called a Ballantine diagram). Before I attempt

Just as as.vector() takes a vector, matrix or array and returns a vector in row-major order, I'd like to write a function to take such an object and return the dimension names, pasted with some separator, as a similar vector. Here is something ugly cobbled together to demonstrate what I want: a function to work for any number of dimensions. vecnames <- function(x, sep=':') {

I'm the faculty member in my department who advises our IT staff on the details of installing R for students and faculty on our Windows 7 lab network. We are about to upgrade from R 3.1.1 to R 3.2.1, and once that is done, this version of R and all installed packages will be frozen in the image that appears in C:/Program Files/R/R-3.2.1/ on every lab computer, and this image is refreshed
