Hi, I just had a very quick look at the StatDataML proposal --- nice work! At the risk of showing my ignorance, I want to mention my first impressions. My first impression is that defining datasets in terms of arrays and list is a bit too high a level. What about simpler vectors, scalars? (I know that R/S don't have scalars, but other systems/applications do.) Can we think of a core

The e1071-group is developping a data exchange package based on XML, called StatDataML. Both read and write functionality is available for R/S and MATLAB/Octave. Now here is a snapshot from the "StatDataML for MATLAB/Octave"-package. It should work fine, but the installation procedure needs some improvement yet. I think the following will nevertheless make it run: 1. Get libxml 2.x

Hi, sorry if this is OT here. I'm trying to compile StatDataML[1] to import Matlab data into R. The R part works fine but compiling the Matlab part exits with this error message (following the INSTALL instructions: autoconf -> ./configure -> make): ,----[ patrick at trurl:~/src/statdatml/StatDataML/MatOct> make ] | make[1]: Entering directory

Hello all, I would like to request that getConnection() and the struct Rconn declarations be added to the R embedded interface. Here's why. It's common in CGI scripts for web applications to direct stdin, stdout, and stderr map to reading from the browser, writing to the browser, and writing to a web log file respectively; very nice and neat. However, things get a little hairy once

Thomas (I'm getting a bit confused about whether this discussion is taking place on r-devel or omega-devel, and perhaps everyone is on both lists) I just posted something on R-devel which I hope addresses many of the points you mentioned, in particular pointing out that I meant encryption for the purpose of authentication, not for the purpose of making something secret, and I was using the

I thought I would take a look at the StatDataML package for some work I'm doing, but I receive the following error when starting: > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 0.1 year 2004 month 11

Hi, Has anyone out there written a function to take a data.frame as input and generate XML that conforms to the DTD for ggobi ("ggobi.dtd")? In other words, like a simple version of the writeSDML function in the StatDataML package, but using ggobi.dtd instead of StatDataML.dtd. It looks easy to write such a function to handle data.frames with only numeric data, but a bit of work with

Hello, I am trying to import data from Matlab.. when i looked up R documentation, it says, package "e1071" have command (read.octave) to import data from octave. but when I tried to install package by using: install.packages("e1071"); I got the following message: ( BTW, my platform is linux version 2.4.18-3 my gcc is 2.96). * Installing *source* package 'e1071' ...

Hi, Why is the following retuning a nodset of length 0: > library(XML) > test <- xmlTreeParse( > "http://www.unimod.org/xml/unimod_tables.xml",useInternalNodes=TRUE) > getNodeSet(test,"//modifications_row") Thanks for any hint. Joh

Is there any function to write a XML structure, after it was read using xmlTreeParse? Ex: library(XML) x <- xmlTreeParse("Irpf2008/aplicacao/dados/12345678901/12345678901.xml") # write it... Alberto Monteiro PS: please, brazilians, don't be offended by my foul language!

Hi useRs, I had posted about Adobe FLEX talking to R for rich visualisation. Reply from Jeffery Horner contained links to the revolution-computing.com webpage which had information pertaining to the Bay Users R group Meetup on Web Dashboards with R. I have a very specific project that I need to implement. I wish to use the graphics capabilities provided by Adobe FLEX to visualise outputs from R.

Hi, we have a first draft of R functions reading/writing data to XML files including a rather general DTD ... which borrows heavily from the data types of a certain programming language :-) The basic idea is to create an XML standard for data exchange, together with import/export functions for as many applications as possible. We here will need R, Matlab & Octave for our research program,

Where I work a lot of people end up using Excel spreadsheets for storing data. This has limitations and maybe some less than obvious problems. I'd like to recommend a uniform way for storing and archiving data collected in the department. Most of the data could be stored in simple csv type files but it would be nice to have something that stores more information about the variables and units.

Hi, I have a problem with spacing in XML files when reading them with xmlTreeParse. I don't know the exact specification of xml but according what I have red before it should work. consider a tiny test.xml file: <?xml version="1.0"?> <fields> <v1>1 </v1> <v2> 2 </v2> <v3> 3</v3> </fields> i.e. I have three fields v1, v2 and

I am trying to read a number of XML files using xmlTreeParse(). Unfortunately, some of them are malformed in a way that makes R crash. The problem is that closing tags are sometimes repeated like this: <tag>value1</tag><tag>value2</tag>some garbage</tag></tag><tag>value3</tag> I want to preprocess the contents of the XML file using gsub() before

How can I use the try catch block such that if this statement fails xml <- xmlTreeParse(xmlTxt, useInternal=TRUE) then this statement is executed xml <- xmlMalFormed() ? This code does not work but assuming its somewhere along these lines: tryCatch(xml <- xmlTreeParse(xmlTxt, useInternal=TRUE), xml <- xmlMalFormed(f1)) -- View this message in context:

Hello! I am crossposting this to R-help and BioC, since it is relevant to both groups. I wrote a wrapper for Entrez search utility (link for this is provided bellow), which can add some new search functionality to existing code in Bioconductor's package 'annotate'*. http://eutils.ncbi.nlm.nih.gov/entrez/query/static/esearch_help.html Entrez search utuility returns a XML document

Can't seem to get the code below working. It gets stuck on line 24 inside the function hm; comments show the line in question. The function hm is called by sapply and is at the bottom of the code. Other stuff above line 24 works correctly including the first couple of lines of the function hm. Should I be using a different apply function or am I doing something wrong with xmlTreeParse ?

Hi, I found an architecture-specific segfault problem with the XML package. I originally found the problem using the parseKGML2Graph function in the Bioconductor KEGGgraph package, but as far as I can tell the underlying issue seems to be with the xmlTreeParse which is called by parseKGML2Graph. I'm trying this piece of code, from the xmlTreeParse help page: library(XML) fileName <-

R Users - I asked about this a few months ago and never did quite figure it out, so with more information, allow me to try again. If I use the following code: library(xml) xmlTreeParse("http://home.comcast.net/~larsenmtl/xmlTestDoc.xml", isURL = TRUE) I receive this error: Error in xmlTreeParse("http://home.comcast.net/~larsenmtl/xmlTestDoc.xml"", : error in
