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)

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

I am trying to run an R script to create a .png file containing a tree map on a headless Linux server using Xvfb. When I try to run tmPlot, I get the following errors and warnings: Error in grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 1 at size 9 could not be loaded Calls: tmPlot ... <Anonymous> ->

Hi, On Windows, with last R-devel tarball (r40647) from ftp://ftp.stat.math.ethz.ch/Software/R/R-devel_2007-02-04.tar.gz I get the following build error: E:\biocbld\bbs-2.0-bioc\R\src\gnuwin32> make ... ... ---------- Making package utils ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata installing R files Error in namespaceExport(ns, exports) :

Hello - I am noticing some strange errors when using the grid package, but (apparently) only after loading the tcltk package. The interaction here does not make sense to me, and I'm wondering if anyone else can reproduce this, or if it is specific to my setup. Here is my sessionInfo: sessionInfo() R version 2.6.2 RC (2008-02-04 r44332) i686-pc-linux-gnu locale:

I've been working on reading and writing yaml encoded documents for the lld project. Michael Spencer added the YAMLParser.h functionality to llvm/Support to help in parsing yaml documents. That parser greatly helps at the syntax level, but you still need to hand write a lot of semantic checking and then convert the various node types in to something usable. I've developed a layer on

I am trying to use ggplot() to produce a graph and am getting warnings that I don't understand. This is happening from within RStudio, but also happens if I start Windows R GUI. Can anyone help me understand the warning and how to make sure the right fonts are designated? The relevant code fragment is: x11(width=7, height = 7) library(ggplot2) # Now some Distance ~ Time plots p2 <-

Dear All, I am looking for: A software to select the lag length for a lag window spectral estimator. Also, I have a small query in the reprex given below. Background for the above, from the book by Percival and Walden: 1. We are given X_1,...,X_n which is one realization of a stochastic process. 2. We may compute the periodogram using FFT, for example by the function spectrum in R. 3. The

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 <-

Hello, I propose two small changes to spec.pgram to get modest speedup when dealing with input (x) having multiple columns. With plot = FALSE, I commonly see ~10-20% speedup, for a two column input matrix and the speedup increases for more columns with a maximum close to 45%. In the function as it currently exists, only the upper right triangle of pgram is necessary and pgram is not returned by

Hello, I submit a patch for review that implements code coverage tracing in the R interpreter. It records the lines that are actually executed and their associated frequency for which srcref information is available. I perfectly understands that this patch will not make its way inside R as it is, that they are many concerns of stability, compatibility, maintenance and so on. I would like to have

Hi, I am new to Ruby, I am a Java expert. I don''t know how to handle the results of a search... I have read a lot, but nobody seems to give examples of that. Do I get an ArrayList from a Table? Do I get fields? How can I identify them? Do I have to parse them to a Class like: Person user = Person(personlist.get(i));? Please, help me... -- Posted via http://www.ruby-forum.com/.
