I'm looking for ideas for creating high-quality plots for use in projected presentations (powerpoint, etc) --- ideally high-quality png, jpg, bmp. The graphics produced using the postscript device look very good. Those generated with win.graph(), png are plagued by the jaggy lines. So far, the only way I can use the postscript plots in my presentations is using separate screen capture

Hi all, One of the things I find most problematic in R is the partial matching of names in lists. Robert and I have discussed this and we believe that having a mechanism that does not do partial matching would be of significant benefit to R programmers. To that end, I have written a patch that modifies the behavior of "[[" as follows: 1. [[ gains an 'exact' argument with

Hi, Using latest R 2.5.0 Patched, I'm unable to install the Matrix package from cran.fhcrc.org.

Hi, On Windows, package files in the inst/ subdir are installed after the lazyload creation. This differs from Linux where inst/ is installed _before_ lazyload creation. Since packages may need data in inst, I think the order on Windows should be changed. Perhaps like this: diff --git a/src/gnuwin32/MakePkg b/src/gnuwin32/MakePkg index 57af321..868e8f1 100644 --- a/src/gnuwin32/MakePkg +++

Hi all, The dict package provides a dictionary (hashtable) data structure much like R's built-in environment objects, but with the following differences: - The Dict class can be subclassed. - Four different hashing functions are implemented and the user can specify which to use when creating an instance. I'm sending this here as opposed to R-packages because this package will

I've been experimenting with install.packages and it's new ability to track down dependencies from a list of repositories and encountered this: install.packages(c("foo", "bar"), repos="http://cran.r-project.org", dependencies=c("Depends", "Suggests")) dependencies 'foo' are not availabledependencies 'bar'

Hello all, I've had the following apropos alternative in my ~/.Rprofile for some time, and have found it more useful than the current version. Basically, my version ignores case when searching. If others find this useful, perhaps apropos could be suitably patched (and I'd be willing to create such a patch). + seth Here is my version of apropos: APROPOS <- function (what, where =

Git is a source code management system like CVS, svn, arch, and others. It would be nice to add exclude support to R CMD build and INSTALL so that the .git subdir of an R package is handled appropriately.

Having used JUnit and PyUnit, I was pleased to see the release of the RUnit package on CRAN. I'm wondering if there are any RUnit users out there that would be willing to share some tips on how they organize their code to work with RUnit. Specifically, I'm wondering about the best way to load/import/source the functions to be tested. I would like to end up with a script, testall or some

Hi, Reading help("Documentation"), I'm led to believe that a help call like: ?myFun(x, sqrt(wt)) Will search for help on the appropriate method in the case that myFun is generic. This isn't working for me. Here is an example using the Biobase package: ## If Biobase is not installed source("http://bioconductor.org/biocLite.R") biocLite("Biobase")

Hi all, I've added a new package 'weaver' to the BioC repository: http://www.bioconductor.org/packages/1.9/bioc/html/weaver.html The weaver package provides extensions to the Sweave utilities included in R's base package. The focus of the extensions is on caching computationally expensive (time consuming) code chunks in Sweave documents. Why would you want to cache code

Hi all, In some circumstances, as.character applied to a list converts real NA's into the string "NA". Propagation of NAs is something R does very well and unless there are good reasons for losing the NA, it would improve the consistency w.r.t. NA handling for as.character to behave differently. Here's an example: ## Create a list with character, logical, and integer NA

Hi, I have a S3 package with namespace called "myS3Pkg". Inside my package I would like to create a S4 class which extends (adds 2 slots) another S4 class from some other package. The class should be created in "myPkg" environment (and not global environment). Using: setClass("myS4class", representation("otherS4class", mydata = "numeric"),

Hi, The warning that was recently added to R-devel about unrecognized escapes has been very helpful in identifying a number of incorrectly specified regular expressions. We are, however, seeing warning messages for Rd files that contiain '\_' and I think that _is_ a recognized escape. Can the check be refined so that '\_' is not warned about in Rd files? + seth
