Hello I need to run an r-file that works on Windows on MAC. The first lines of the file are: library(R.matlab) library(Rcompression) Somehow I cannot find where Rcompression is. Am I missing something? Many thanks Ed

Hi, I am trying to load into R a MATLAB format file (actually, as saved by octave). The file is about 300kB but R complains with a memory allocation error: > library(Rcompression) > library(R.matlab) Loading required package: R.oo Loading required package: R.methodsS3 R.methodsS3 v1.2.0 (2010-03-13) successfully loaded.

...apply changes to the labelling or so, and I haven't found a plugin or an application which does this batch in OOorg. Is there new development on a direct import package for ODS files? I've googled around one afternoon, found ROpenOffice (http://www.omegahat.org/ROpenOffice/) which requires Rcompression (http://www.mail-archive.com/r-help at r-project.org/msg55480.html), which in turn is quite outdated.

I think it may be because Java?s Deflator class by default (see below ... the nowrap parameter) writes the data without the header and checksum. I can't change the Java creation code. I think uncompress() reads a zlib package (with headers) and gunzip() reads...

Dear Group, I am looking for ways to use R and Matlab. Doing the data transformations in R and using the data in Matlab to analyze with some pre-defined scripts. Any good ways to transfer the data into matlab in its most recent version? I tried using R.matlab but the writeMat output is not readable by Matlab. I just need to output a data.frame and read it as is into matlab where I can do any

...ice, once with all Suggest package hidden or once, if $R_check_force_suggests=1, with all Suggest available? BACKGROUND: I just had a case where my R.matlab package passed all R CMD checks on my local machine, but when I uploaded it to CRAN it gave an error there. R.matlab has Omegahat's 'Rcompression' package listed under Suggest: in DESCRIPTION. I've put it there, because it is optional. The example(readMat) scans an inst/ directory for *.mat files and asserts that they can be read. One of them required 'Rcompression', which is not installed by the CRAN servers. I can of co...

Hello, I have a binary file type that includes a zlib compressed data block (ie not gzip). Is anyone aware of a way using base R or a CRAN package to decompress this kind of data (from disk or memory). So far I have found Rcompression::decompress on omegahat, but I would prefer to keep dependencies on CRAN (or bioconductor). I am also trying to avoid writing yet another C level interface to part of zlib. Many thanks for any pointers, Greg. -- Gregory Jefferis, PhD Division of Neurobiology MRC Laboratory of Molecular Biology...

Can one write a zip file from R? I want to create a file with a name like "dat.zip", being a zip file containing "dat.csv". I can create "dat.csv", then call "system('zip -r9 dat.zip dat.csv')". Is there a better way? I can use "gzfile" to write a gz file, but I don't know how to give that a structure that would

To make R.matlab's readMat work for me[1] I needed access to zlib's uncompress function. R already links with zlib, and sometime last year I hobbled together a quick package to get at a few functions. It's my first package, so I would love feedback both on the package and its purpose. I've dropped a temporary copy at http://jriedy.users.sonic.net/internalzlib_0.1.tar.gz Could

Dear R-people, I am trying to read a matlab file, unfortunately without success. I enclosed the zipped file. Do you have an idea how to read this file by ReadMat package into the R system? Thanks for your time! Wim Krijnen
