similar to: loading .RData on distributed system

Hi, I am developing a tool for converting a large data frame stored in an uncompressed binary (XDR) RData file to a delimited text file. The data frame is too large to load() and extract rows from on a typical PC. I'm looking to parse through the file and extract individual entries without loading the whole thing into memory. In terms of some C source functions, instead of doing

Dear all, I have a version 1.3.1 of R which is under Linux Redhat. I have worked with it without any problem. But now when I try to run R, I get the error message as follows : Error: an xdr real data read error occured Fatal error: unable to restore saved data in .RData Thank you in advance and sorry if my question is perhaps simple.

Hello, I am a developer working on extracting information from .rdata files using java. I have been looking through the documentation a lot trying to figure out how to read these files, but am a bit stuck at the moment. I have generated two .RDATA files from StatTransfer and have noticed that they both begin in similar ways. *File 1* RDA2 A 2 131585 66560 1026 1 4105 10 .Traceback 254 1026 1

Currently, I load the RData file then ls() and str(). But loading the file takes too long if the file is big. Most of the time, I only interested what the variables are in the the file and the attributes of the variables (like if it is a data.frame, matrix, what are the colnames/rownames, etc.) I'm wondering if there is any facility in R to help me avoid loading the whole file.

Dear R-help, I've run into a problem loading .RData: I was running a large computation, which supposedly produce a large R object. At the end of the session, I did a save.image() and then quit. The .RData has size 613,249,399 bytes. Now I can't get R to load this .RData file. Whenever I tried, I get "Error: vector memory exhausted (limit reached)". I tried adding

Hi All, Can i install * on a beowulf cluster or Is * compatible to clusters. I am planning to install a 4 node beowulf cluster using few cheap hardwares. If no one had tried before i can spend some time on installing and configuring * on this cluster. Let me know. thanks, -Balaji --------------------------------- Do you Yahoo!? New Yahoo!

If a move toward machine-independent representation seems reasonable, it may be worth looking at some of the binary data exchange formats used by nasa and others, CDF http://nssdc.gsfc.nasa.gov/cdf/cdf_home.html netCDF http://www.unidata.ucar.edu/packages/netcdf/index.html HDF http://hdf.ncsa.uiuc.edu/ There may also be something useful in the "Scientific Data Format Information

Dear R-help, Has anyone tried running R on a Beowulf-type cluster? I can get R to run in batch (using R CMD BATCH) on a cluster, but am wondering if it is possible to get an interactive R session on a compute node. Right now, if I run: beorun --nolocal R I just get the R start-up message and back to the shell prompt. If I try bpsh 0 R I can get R started (but the R prompt does not

Dear r-help, I am having an intermittant error using R on a linux beowulf cluster. I am using my homebrew script to test the performance of various feature subsets with "lda". ------------- The general procedure is as follows: I load the data from an .Rdata file (which has generated by R-1.3.0) run my script "Iterate()" ... At a different iteration each time I get the

Hi I am after a solution where i can easily kickstart many, read hundreds, of boxes in a short time frame. Perhaps the way i install software is to actually re-kix the box with a new software baseline - that type of idea. I have looked at rocks and it looks good but it seems a little rigid in that i need to be able to determine certain things like hostname etc as in our env hostname

Hi, everyone. One of my .RData files has been corrupted, and I have some things from the last couple of days that hadn't been backed up yet that I would like to recover rather than recreate if possible. Is there any way to fix a damaged .RData file? Thanks, Matt Wiener -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

[Sorry for possible duplicated thread.] Hi. I''m new to Xen and I would know if it works well in a cluster environment (Beowulf, OpenMosix, CoLinux etc). I need an HPC running some virtual machines. Is this possible with Xen? Regards. -- Allysson Steve Mota Lacerda Administrador de Redes http://www.stevelacerda.net _______________________________________________ Xen-users mailing

Hi all, without winbind co actually we have running samba 4.5.16 under Devuan 2.0 (Ascii) as AD member without winbind configured. UID and GID informations coming from NSS (nslcd -> LDAP). LDAP and AD are in sync. After upgrade to Devuan 3.0 (Beowulf) with samba 4.9.5 this constellation does not work anymore. Samba insists on configuring winbind. Can I configure winbind to use

Hello All, I'm suffering from a corrupted .RData which I believe arose from a shutdown while the session was in the process of saving the image. I wonder if theres something I can do to recover the data? (the fatal error message is contained below) Unfortunately, there was quite a bit of new code prior to my latest backup, which I would hate to rewrite. kind regards andy

I want to migrate my R workspace databases (e.g., .Rdata) from Windows to Linux. The R help file for "save" says that "[a]ll R platforms use the XDR representation of binary objects in binary save-d files, and these are portable across all R platforms." Is it is simple as that? Copy the Windows .Rdata file to the Linux .ext3 file system? Thanks, Derek Derek N. Eder

Hi all, I have successfully made and installed both gdal, and proj.4, but still cannot get rgdal to be installed in R. I think i'm very close. I do not have root access, if that matters, i've installed everything locally. I'm using debian on a beowulf cluster. I call: install.packages("rgdal", .libPaths()[1], configure.args =

I've just had an interesting thing happen to one of our students. He's using R 1.9.1 on Linux, and so I dont expect bugfixes, I'm just reporting this out of interest in case anyone else has had this happen. Starting R caused a seg fault shortly after "[Previously saved workspace restored]". Running "R --no-restore-data" worked fine so I suspected a corrupted
