I wondered if there were standard practices in CRAN for delivery of R source implementing functions in R packages. I has encountered a couple of packages where the gzipped version of source contains very little, primarily the Help files describing the functions in the package. In some cases I can find the source as the value of the function name. Given that these packages are released as GPL,

....11.0, users get the embarrassing notice about a disconnect, and cannot do much about it. If it is tedious to roll out a new package on time, perhaps there's a possibility for automation here. Thanks. I encountered this yesterday with RHmm. I'm running R on WinXP. Happy R user! - Jan Galkowski.

...acks such a parameter, and the documented "type" parameter has only "response" offerred. Is there some way of obtaining prediction bands from lmRob? Is there an alternative robust (linear) regression package that offers such a capability? Thanks for any and all help. - Jan Galkowski, Akamai Technologies, Cambridge, MA.

...g R magic or package which might let me recover the value of the scalar quantity so represented given the RGB values at each point in the picture? After processing, I'd also like to push the results back through the translate to get an RGB JPEG again. Thanks for any and all pointers. - Jan Galkowski

Apologies if this is the wrong place to ask. I'm not aware of a mail list devoted to database interfaces. Please direct me if so. I am trying to use TSMySQL. It loads RMySQL, and apparent the CRAN version has an .onLoad script which seeks out the local MySQL server. If that fails, the package fails to load. Thing is, I'm trying to access a MySQL database on a remote machine for which

Recently, a package for convex optimization was announced for Python, based upon the LP solver GLPK, the SDP solver in DSDP5, and the LP and QP solvers in MOSEK. I'm aware GLPK is available for R, but wondered if anyone had good packages for convex optimization along these lines for R. TIA.

...R 2.9.1 has anything built it to do that? Is it as simple as moving something like Rprofile.site from one machine to the other? I had a look at R-admin.pdf, and although it talks a lot about configuring on various systems, it did not address this directly. Also looked at RSeek. Thanks. --Jan Galkowski, Akamai Technologies

Can someone point me to the proper place in the documentation or on the Wiki where I can learn how to get R to stop interpreting the string "NA" as something special? I have a table in a database which contains (among other things) country codes and continent codes. The standard set of two-letter codes includes "NA" to denote "North America". I learned of the

Joyful. I'm adapting a FORTRAN 77 package for use with R. Pretty straightforward. Except for a glitch it took me some time to figure out. This existing package has subroutines which have parameters called "NA". So, I called subroutines like bnodes <- function(n, lst, lptr, lend, nodes, nb, na, nt) { ensure.all.numeric(list(n, lst, lptr, lend, nodes, nb, n.a, nt),

There's Renka's STRIPACK, and TRIPACK, respectively, ACM TOMS Algorithms 772 and 751, and there's the R package "deldir" which does the Delaunay for a plane, but does anyone have or know of the tessellation in R for a sphere? Also, is there a standard indexing scheme for Delaunay facets, and perhaps of edges in such facets? I'd expect that to be a publication reference,

I'm interested in the Rsolnp package. For their primary function "solnp", one example is given, and there is a reference to "unit tests". Anyone know where these can be found? Also, Rsolnp is used in a few other packages (e.g., depmixS4), but I cannot seem to find source illustrating its call sequence, and the precise definition of the functions passed. Can anyone help?

I wanted to put this on the R Wiki, but found the suitable pages were read-only. I wanted to get it out in public to save people work. I was converting dates like "2009/03/26 01:00:00 AM" using as.POSIXct. I found that using a format of "%Y/%m/%d %I:%M:%S %p" did not work correctly to distinguish AM from PM. Both were converted into the same timestamp. Indeed, what I found

Like many software assemblies, R is updated frequently. Also, it creates its own release-numbered directory when it is installed. Packages get dumped into the subdirectory "library". I have a personal habit of storing documents related to R packages in the "doc" subdirectory. Here are my questions. (1) How do people manage an upgrade, from 2.6.1, say, to 2.6.2? 2.6.2 will

The package "sm" was obtained twice, one using R's built-in updating of packages, the second directly. In both cases the USA-NC CRAN mirror was used. In both cases, loading the package under R 2.10.1 for Windows resulted in a 'package obsolete' kind of message. Switching the mirror to USA-CA-1 (Berkeley) got a good package that loaded without complaint. R version 2.10.1

Hi group, I found a module for adaptive kernel density estimation for Stata users, but unfortunetly I don't have access to Stata, can I find a similar approach using R? Thank u so much 4 ur time. [[alternative HTML version deleted]]

I'm interested in the R packages svLab and the recently announced denstrip. For svLab, I've seen a PDF from 2003 describing it, and at least one paper or description having used it. I could not find it in the download list of packages within R or on CRAN, however. Did it get subsumed or renamed? Regarding denstrip, this was just recently announced, so I wondered what the percolation
