similar to: First sample release of the R-Orca package.

I've been having fun with crashes recently, both with Blackdown JDK and the IBM JDK, while building up the ROrca interface. It's just not stable for me, and my lack of grokking the intimate details of lazy evaluation is not helping. Brushing works, though, which is nice. I need a bit more stability before I get the "data add/change" features in line, though. Anyway, other

It's cool, it's exciting, and much thanks to Duncan. He announced RJava yesterday (or this morning?) on the R-devel list, and it's really worth it. http://www.omegahat.org/RSJava for more details. But it does mean that we can run Orca code directly within R, (without Thomas' socket connections) (and also means that we really need a "stop" button, since killing

Thanks to Duncan's recent work on SJava, I've got a (so far) stable platform to put together the R-Orca interface (dynamic graphics, including brushing, subseting, etc). While the first version will be looking at installation issues and study basic user interfaces for providing a few working examples, it will be important for this particular package to look at how one integrates a

Dear R People: Is there a binary version for rorca, please? Thanks, Laura mailto: lauraholt_983 at hotmail.com R Windows 1.9.0

Okay, so I've got a set of directories containing unpacked R packages (unpacked, since for various sensible reasons, I'm editing them in warped ways). Supposing that these are in: /home/rossini/Runpacked I thought I could do something like: install.packages("MyUnPackedRPackage", # top package name lib="/home/rossini/lib/R", # where

What about "Rtips" at http://lark.cc.ukans.edu/~pauljohn/R/statsRus.html ?

One thing that has driven me batty to no end is the fact that ESS doesn't handle R's "exit" well. Any thoughts as to the default? I'm thinking of something like: current: do what currently is done C-u Y C-c C-q : quit and save workspace C-u N C-c C-q : quit and don't save workspace. Comments? best, -tony -- A.J. Rossini Rsrch.

(please keep sebastian cc'd) Doug - we are managing to trigger, both on R 1.1.1 and R 1.2.0 (proper versions of NLME), the following: > warnings(model1) Warning message: Singular precision matrix in level -1, block 1 Error in cat(list(...), file, sep, fill, labels, append) : argument 2 not yet handled by cat > suggesting either an "inappropriate" use of cat(), or a

for Spam. In the process of setting up a more effective spam filtering system, I just noticed that bogofilter, which implements extensions of the (a?) "Naive Bayes" text classification approach, will dump out R data frames; the man page suggests how to "integrate" it with R for verification. (sort of, that is). Anyway, for those of you looking for silly and perhaps

In order to quickly install lots ("all") of CRAN packages on a nice new machine here, I did the following: install.packages(CRAN.packages()[,1]) 1. Is this sensible (other than the obvious, "who needs everything"?) 2. Should this be made easier to do (added as a possible option)? best, -tony -- A.J. Rossini Rsrch. Asst.

Is there a simple way to determine at run-time the directory with HTML version of help pages? (to see where I'm heading here, if you've got w3 installed under (X)Emacs on Unix _or_ a Microsoft OS, do w3-find-file and load $(R_HOME)/library/html/whateverfunction.html It's slightly nicer than the standard ESS text-help. best, -tony -- A.J.

I know that this was a topic in March at DSC, but I was suffering from a nasty migraine that prevented me from paying as much attention as I ought to. What's the current state-of-the-art regarding packaging/serialization of R objects? Or is it still vaporish (i.e. nothing built)? I'm a bit more interested in functions/closures than "ordinary data". best, -tony -- A.J.

So, lots of comments about PICT. If you have to go there (EPS to PICT, but vectorized PICT for an investigator to use), does anyone have suggestions? I've found EPStoPICT (www.artage.com), any other thoughts? (these are real Mac people, so while I could go the WMF route, it's about as palatable as EPS). best, -tony -- A.J. Rossini Rsrch. Asst.

Not having a Mac in front of me, but having a consultee with one, I pose the following question: Is there an easy way to transfer a Mac excel data set (columns, etc) into R (only on a Mac)? Verified existence of such a thing would be great; I've been uncertain as to the best way to get data in/out of R (on the mac, of course). An actual algorithm/procedure would be met with great rejoicing.

There's a bit of a symmetry issue, which may or may not be important (led to 15 seconds of confusion until I got my bearings straight): row.names, rownames; colnames, no col.names? I _NOW_ realize the difference between row.names and rownames, but is there any reason not to have col.names for re-naming columns in a data.frame? (if there is, I don't particular need to know it, but it

Thanks to Tony Plate for letting me know what the abbreviate.arg option does. I think this could be made more flexible (I.e. =TRUE, =FALSE, =#, where # would be passed to the abbreviate min.length argument). But it follows the example I was given. "print.factor" <- function (x, quote = FALSE, max.levels=5, print.levels = {if (max.levels==0) FALSE else TRUE},

could we add an argument to suppress printing of levels for print.factor()? i.e.: print.factor <- function (x, quote = FALSE, print.levels = TRUE, ...) ## MODIFIED { if (length(x) <= 0) cat("factor(0)\n") else print(as.character(x), quote = quote, ...) if (print.levels) { ## ADDED cat("Levels:
