similar to: installing packages from CRAN, is this approach stupid?

seek(zz,where=NewPosition) returns the OldPosition of connection zz (of the appropriate "pointer", i.e. read or write). Currently, the docs have: > Details: > > `seek' with `where = NA' returns the current byte offset of a > connection (from the beginning), and with a positive `where' > argument the connection is re-positioned (if possible) to

Suppose one wanted to build an R wizard for packaging... One would need to specify and create: package-name/ package-name/Description package-name/INDEX package-name/R/ package-name/man/ package-name/src/ >From this, we'd "probably" like to: - script-up the Description - provide a script for regenerating INDEX by calling out to the

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

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

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.

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.

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},

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

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:

Duncan - (but sent to R-devel, for any other thoughts?) How do you envision RSPerl being used? Without having seen the details, I can think of playing with strings; is there a preferred incantation for stringification of R objects (serialization)? (actually, the main problem I'm having is that I know how I want to code something like: Robject <-
