similar to: relist() is broken when the skeleton is a list with empty list elements

Hi all, I wrote a function called relist, which is an inverse to the existing unlist function: http://www.econ.upenn.edu/~clausen/computing/relist.R Some functions need many parameters, which are most easily represented in complex structures. Unfortunately, many mathematical functions in R, including optim, nlm, and grad can only operate on functions whose domain is a vector. R has a

Dear all, The following code is inspired by the help file for the relist() function (see?relist), which explicitly details how you can use a relistable object in conjunction with optim to pass and reconstruct complex parameter structures/groupings. The idea is that the optim() function can only work with vectors, but in many cases you would like to use a complex structure inside the objective

There are a few typos in the documentation for relist(). I've also made a few other changes to the file which I believe are improvements. I've attached a patch against the version under the 'trunk' branch on the svn server checked out today. It was produced by diff -u /usr/local/src/R/R-svn-trunk/src/library/utils/man/relist.Rd ~/relist-new.Rd I'd also suggest identical()

Dear list, I think I just stumbled across a bug in either 'relist()' and/or 'as.relistable()'. It seems that 'pairlists' can only be un- and relisted as long as they're not nested: Good: a <- as.relistable(as.pairlist(list(a=1, b=2))) a <- unlist(a) relist(a)# Works Bad: a <- as.relistable(as.pairlist(list(a=1, b=2, c=list(c.1=1, c.2=2)))) a <- unlist(a)

Hi, Wouldn't it be awesome if package.skeleton() could be used to produce, well... a package skeleton? In a fresh R session: > package.skeleton("mypkg") Error in !have : invalid argument type This (not very informative) error message seems to occur because I'm trying to create a skeleton with no flesh on it: > foo <- function() {} >

I think the optim() example in the Details section of relist()'s help page is not totally correct. In particular, in the current form it is not taken into account that vcov should be a symmetric matrix and only the parameters in the lower (or upper) triangular part should be optimized. A possible fix is: ipar <- list(mean = c(0, 1), vcov = c(1, 1, 0)) initial.param <-

By any chance is there a skeleton package to use as a template to develop an R package? I downloaded "Writing R Extensions", which was evidently updated pretty recently, but I did not see any references (and of course I may have totally missed it) to a package template to use as a go by. Does such a skeleton package exist? Thanks again for all your help, as I've got the code,

Hi, I know this has been reported/asked before ( http://tolstoy.newcastle.edu.au/R/e15/devel/11/10/0831.html) but it would still be just nice to have a fix for the not user-friendly fact that one cannot create a completely empty package skeleton (see previous post for a suggested patch). In the same vein, I would add to the original suggestion from Herve Pages that it would be nice to have a

Hello, I have a function with a long list of parameters (of different types, numeric and string) myFunc <-function(p1, p2, p3, p4, p5...etc) { do.something(p1,p2,....) } I want to loop over this to provide a different set of parameters to the list every time. for (ii in 1:N) { myFunc(p1(ii), p2(ii),....etc) } I would like to simplify the notation and use some kind of structure, maybe

Hi there, we just encountered a problem with some tools obviously encoding into the skeleton format by default, which leads to problems with several other tools, in that particular case it's oggCut. When we try to edit/cut an ogg file with it, the program crashes with a segfault. I was able to locate and fix the problem in the oggCut source but I am wondering how to convert my ogg files to a

Hi, I just added skeleton meta data output support in speexenc. The option is disabled by default and can be enabled using -k or --skeleton. I'm using a very simple skeleton API for handling skeleton packet generation which is contained in skeleton.h & skeleton.c. Please check the patch and whether xine/mplayer/quicktime and other players support the skeleton enabled speex file. At the

Hi, all. I was trying to build my R package with R 2.15.1 32bit and win7. I basically follow the routine in Steven Mosher's blog http://stevemosher.wordpress.com/step-10-build/ After I fixed the path, and built the skeleton of the package, I started command prompt and used the following commands in building my package Rcmd check myPackageName Rcmd build myPackageName Rcmd check

I'm patching oggenc with this fix. If Conrad reports success in his test, I'll go ahead and patch all other implementations I can find. -Ivo

Hi everybody, I've updated OggIndex to now output Skeleton 4.0 tracks. The differences between Skeleton 3.x and Skeleton 4.0 with OggIndex is: * The fisbone packet now includes a "Radix" field. * The fisbone packet now includes two new compulsory message headers; "Role" and "Name". * The fishead packet no longer includes "start time"

Hi All I'm currently trying to put together an ogg file with two theora streams, a handful of audio streams (probably mixed vorbis and opus), and a Skeleton stream that describes their relationships to each other. I had hoped to be able to use the oggz suite of tools, but I can't seem to get that to work. To generate my theora files, I'm using ffmpeg2theora, which will happily

Hi the list, I am using package.skeleton on a file that has a very classic name, but package.skeleton detect it as a invalid name : --- 8< ------- package.skeleton(name="packClassicBis",code_files="./packClassic/R/progClassic.R") Cr?ation des r?pertoires...

Hi the devel list I am testing package.skeleton in R 2.7 (download today). I get an error that I do not understand. I guess it is not an error from my code since I have no probleme when I source it. So is it a error in package.skeleton? Here is my code : --- 8< ------ File essai.r ------------- setClass( Class="ClusterizLongData", representation=representation(

Hi again, yesterday I mailed this query however I could not see this on the mail list. Therefore, I am reposting it again. I was using package.skeleton() function to create the skeleton of my package in windows. Here is my attempt: rm(list = ls()) setwd("F:/R_PackageBuild") package.skeleton("trial1", namespace = TRUE, code_files = "F:/R_PackageBuild/trial.r") In
