similar to: seek() and gzfile() on 32-bit R2.12.0 in linux

I'm putting together a data package and am finding that I get enormous savings in space by using bzip instead of the usual gzip in save(). Is it safe to assume that for R versions, say >= 1.7.1, that the function bzfile() will always be available? Thanks, -roger

I often want to use "pipe" with "readBin" to read (binary) data from the standard output of a Perl or C program. For that I need "pipe" to work with the "open='rb'" option. It never worked for me, and after a look at the connections.c file, I see that in "pipe_open" the mode gets passed directly to "popen" (I'm using Linux on

When executing 'dyn.load("this/dll/does/not/exist.dll")' the resulting error message is scrambled. Not all characters will be displayed and when I select the empty region text disappears/reappears. For a screenshot see: http://dl.dropbox.com/u/2602516/dyn.load_error1.PNG and http://dl.dropbox.com/u/2602516/dyn.load_error2.PNG. Note: I had the same problem with xlsReadWrite

Argh, just now I saw a scrambled start-up message when running xlsReadWrite1.5.2 in R2.12.0 (32-bit) on a Win7 64-bit platform. If you have this situation and use xlsReadWrite 1.5.2 (probably all earlier versions also) you can download a quick fix, see below. I don't know if this also affects Vista/XP 64 bit. - Probably on the weekend I'll have time to release a proper new 1.5.3 version.

Hi all,I have large compressed text tab delimited files, I am trying to write efficient function to read them, I am using gzfile() and readLines() zz <- gzfile("exampl.txt.gz", "r") # compressed file system.time(temp1<-readLines(zz )) close(zz) which work fast, and create vector of strings. The problem is to parse the result, if I use strsplit it takes longer

Dear R Group Can any body point me to a link from where I can get zip archive of the package HH for R 2.12.0?

Hi, I typically install new versions of R on windows using the downloadable executable file rather than the full tar. I need to now document the success of the installation in addition to my preferred procedure of running an old dataset against the new build. I found quickly that this is all available to me but the tests directory I have does not contain the scripts that the tar file does. How

Hola: Para el desarrollo del nuevo PluginR de Tiki (para poder ejecutar scripts de R desde Tiki: en páginas Wiki, hojas de cálculo web, etc, http://dev.tiki.org/PluginR ), por ahora estamos usando la lista de funciones que se usaban en el proyecto r-php, y que fueran heredadas por la extensión R de MediaWiki. Como r-php se hizo hace algunos años (2006), me pregunto si alguien sabe si hay

This might seem like a strange question but is there any way to compress an R object (such as a matrix) and know its resulting size in bytes ? Clearly, I could implement this in the following way (if x is my matrix): zz <- gzfile(fname,"w"); write.table(x,zz); close(zz); file.info(fname)[,"size"]; However, I need to do this for hundreds of thousands

Hi, I have downloaded a bunch of bz2 files. I wonder if R will be able to unzip them in a batch mode or even one at a time? I was looking at the unz function. But it didn't work well. Say I have a bz2 file in H:/Temp/65502805_532.pair.bz2. Anyone has any suggestion? thanks John > setwd("H:\\Temp\\") > getwd() [1] "H:/Temp" >

Hi I have been trawling the web, FAQs, and R manuals for help on the following issue, but have failed and was wondering if anyone has a solution to the following problem: After having installed R 2.6.2 for Windows (binary), I tried to install various packages.

Is it just me, or did a corrupt PACKAGES.gz file get installed in the bin/windows/contrib/3.2 directory of CRAN mirrors recently? gzfile() complains about it and Cygwin's gzip cannot decompress it.

Hello, If repeated calls are made to save() using the same pre-opened gzfile connection to a file, and then the connection is closed, the objects saved by the second and subsequent calls are not correctly restored by repeated calls to load() with a new gzfile connection to the same file. What follows are a session exposing the bugs, analysis (see ANALYSIS), patches (see PATCHES), and a session

When I read a .gz file with readLines() in 3.4.3, it returns text (and a warning). In 3.5.0, it gives a warning, but no text.
