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.

...ux-gnu (64-bit). Up to yesterday everything ran fine with jobs in several blocks (block1, block2 etc) of submission. They are sent to an LSF platform to handle the parallel submission. Today I see that only one of the blocks (the 19) has not finished correct: It reports in the out file: Error: ReadItem: unknown type 98, perhaps written by later version of R Execution halted Checking through google one had recommended rm ~/.RData I applied it, but the run again fails, when submitting through SAS for block 19.

Dear r-devel readers, I have a pretty deep problem with package loading and unloading in the development version of the lme4 package <https://github.com/lme4/lme4>; it's not boiled down to a properly minimal example yet (this has been difficult), but I am posting anyway in the hopes that someone has ideas about how to proceed farther, since I'm nearly stumped. Apologies in advance

I have run into a problem loading a just saved R object using R-devel. I have been saving and loading this particular type of R object for a long while and never ran into this problem. I save, then immediately reload (to test save) and get "ReadItem: unnknown type 65". This error is reproducible after logout from server and restart of emacs and R. Below is my output and sessionInfo(). Thanks, Mark > setwd("~/Genomics/Experiments.Genomic/BB01/acb.shell") > local(save(affy.object.preprocessed, file ="affy.object...

Hi, I ran a program that was exhausting the (unix) server's available memory. I got a bus error and then chose to save and quit workspace (option 4). That may not have been a smart idea - when I try to use R now, I get the error message: Error in load(name, envir = .GlobalEnv) : ReadItem: unknown type 0, perhaps written by later version of R Fatal error: unable to restore saved data in .RData I deleted my temporary R directories but still get the same message. What can I do to change this? Best, Ralph _________________________________________________________________ family_s...

Hello, I was reading through serialize.c and i couldn't answer something. In readItem, case CHARSXP, rules exists to adjust the read string for string encoding. Q1. I couldn't find where the encoding of the elements of the string vector are written? Is it when writeItem writes out the attributes of the item? But i couldn't find encoding in the attributes field x <- &q...

Dear list-members, I have observed quite a strange problem with the date package. You will find below what I get on my machine (Ubuntu). I have been able to reproduce the error on Red Hat too.

Hi, While installing precompiled packages I often get warnings like the one in the subject. I usually ignore them, but I still do not understand why windows packages are build with unreleased versions of R. Is there some way to get packages build under R-2.2.0? What are potential problems that can result from that version mismatch? My system: winXP R version: 2.2.0 Jarek Tuszynski
