Hi, Today I came upon unexpected R behaviour. I did some modelling and the result was R object, about 28MB size (nested list, with matrixes as list elements). When I was saving the session with save.image, the resulting .RData file was 300MB. There were no other large objects: >

Hi, I'm having problems while working with large data sets with R 1.5.1 in windows 2000. Given a integer matrix size of 30 columns and 15000 rows my function should return a boolean matrix size of about 5000 rows and 15000 columns. First of all I tried to run this function on computer with 256 MB of RAM. I increased memory limit of R with memory.limit() up to 512 MB. I was inspecting

Dear all, There have been one or two questions posted to the list regarding the optim error "non-finite finite-difference value [4]." The error apparently means that the 4th element of the gradient is non-finite. My question is what part(s) of my program should I fiddle with in an attempt to fix it? Starting values? Something in the log-likelihood itself? Perhaps the data

Good day, Is there any way to save a plot produced by R in a LINUX (Debian) machine? The window opened by R to put the plot in, does not give any option to save it (there are options to move, close, minimise it, etc. but not to save it). How do you do that?

Hi, Dirk Eddelbuettel advised me to write here. Here is my original letter to him: I would like to enquire about package r-cran-rjava on Debian jesse. It seems that if default-jre package is not installed, but openjdk-7-jre is installed, then library(rJava) in R fails. I?ve been bitten by this today and I wonder whether this an issue of mine, or is this a possible bug. My server admin used

Hi, Sweave for some reason does not respect encoding setting in pdf.options. Everything is OK with ps.options. Thus when using non-default encoding for graphs, resulting graphics eps file is correct, but pdf file is not. Workaround is very simple, just use latex->dvips->ps2pdf chain to get the intended pdf document. I tried to find the explanation for this, but I did not find anything. If

Hi, Is it possible to make R start not from terminal with option --gui=GNOME? Now if in the launcher preferences checkbox run from terminal is not checked, R with option --gui=GNOME doesn't start. If started with checked checkbox, i.e. from terminal, besides R, terminal window also appears, but it is of no use. Yet if it is closed, the R window closes together. Is this a feature, or is

Subject: Error: cannot allocate vector of size 554 Kb X-Mailer: VM 7.00 under 21.4 (patch 6) "Common Lisp" XEmacs Lucid Reply-To: fjmolina at lbl.gov FCC: ~/mail/sent Does anyone know how I can avoid this error? Error: cannot allocate vector of size 554 Kb I think my computer should have enough memory to allocate such vector.

Hi, Today I came accros a very interesting thing. I was asked how much time it takes for R to calculate the product of two large matrices. So I generated two 2000x2000 matrices of random normal numbers and measured the time with function system.time m1 <- matrix(rnorm(2000*2000),2000) m2 <- matrix(rnorm(2000*2000),2000) system.time(m3 <- m1%*%m2) and it produced 46.47 0.36 47.68

Dear list, I have a simple question. If I need to run linear regression on a subset of the dataset, will the following two commands give the same output: lm(y ~ as.factor(x1) + as.factor(x2), data, subset = z==Z[1]) and lm(y ~ as.factor(x1) + as.factor(x2), data[data$z==Z[1],] ) I have got different results running the two commands. Am I missing something here, or it there a bug on the

Dear list members, A new package, called *midasr* (version 0.1), is now available on CRAN: http://cran.r-project.org/package=midasr This package provides econometric methods for working with mixed frequency data. The package provides tools for estimating the time series MIDAS regression, where the response and explanatory variables are of different frequency, e.g. quarterly vs monthly. The

Hello! A friend of mine tried to install R 1.0.0 on a Linux SuSE 6.4 with new compilers and new X. First the X-libs could not be found. Using the apropriate flags to change the paths for X-libs for configure (deleting first configure.cache) did not solve the problem. So he copied the libs to the expected /usr/X11/lib/ resp. include (because linking was not possible) it compiled fine up to the

I am trying to write a "thumbnailer" for the thunar file manager that can process .ogg files containing a video stream and produce a thumbnail of a particular frame. The only trouble is telling which files have a video stream in an efficient method. The best I've come up with is running ogginfo on every file with the mimetype application/ogg. Is there a better method? I know

Hi, I am investigating a problem for which I found no solution. I have a matrix with two columns. I have plotted it as an x-y plot (plot(matrix[,1],matrix[,2]) But this is not apropriate for my purposes. I need to group the data in matrix[,1] into groups (as an histogram would do). Then I have to calculate the average of matrix[,2] for each group. Before starting with loops and loops I

I am working on wxFileType and wxMimeTypesManager, most of which I have done but I had to comment out a nested class in wxFileType and the methods that use it. Does anyone have a clever way to get around nested classes since SWIG does not currently support them? Sean

Following up on #190 [1], I''ve just added a simple patch that allows the manipulation of the TYPES hash from within the Merb module. Use like: Merb.add_mime_type(:png,%w[image/png]) Merb.remove_mime_type(:png) It specifically disallows the removal of the :all MimeType, since content negotiation relies on it. I''m not super wonderful at API design, so comments and

Dear R core, influenced by recent panel discussion in Vienna I think that it would be nice to add package specific output of citation() function to package reference manuals. I think that apropriate place would be just after fields from DESCRIPTION file. This will be OK for CRAN, but not for locally installed packages as there is not reference manual there (at least on my linux box) - why is this

Hello I have been setting up my computer to run Sweave. I have got the whole thing working on example files, except that my MikTex returns an "Undefined Control Sequence" error for \Sexpr and my output file contains verbatim code sequences at the apropriate point in the text rather than the R output. The rest of the output file is fine with tables, R code sequences and figures in the

Indexing mail attachments with Dovecot + Solr. This patch has been tested with these versions: * dovecot 2.0.9 * apache-solr 1.4.1 This is a patch for the fts-solr plugin (that indexes mail messages for Dovecot with Solr). In main stream, the plugin does not index attachments; With this patch, you can index mails and their attachments (pdf, docs, openoffice docs...) . You can get others
