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, While running R CMD build on one of the Bioc packages, I'm getting the following error message * creating vignettes ...

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I''m using the "delete_lines" definition from http://reductivelabs.com/trac/puppet/wiki/SimpleTextRecipes . However, when I use it to remove a line with the pattern "/proc/kmsg" I need to escape the slashes for sed/grep and so I end up with "\/proc\/kmsg", but then I get this notices in the log of

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'

I've recently come across two pieces of code using calls to callGeneric() inside the definition of a method. In both cases, it appears to me that the callGeneric call could be replaced with a "real" call to the generic, say foo(x) instead of callGeneric(x) inside method foo. My understanding from the docs is that when called with arguments, it is just like calling the actual

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.

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")

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.

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
