similar to: lm Regression takes 24+ GB RAM - Error message

Dear R helpers,   I have two queries.   (1) If the dataset contains some variables having all the entries = 0 and while analysing I want to delete those pericular columns, how do acheive this. i.e.   dataset1   sr_no    var1      var2       var3        var4        var5 1           5           0          3              1           0 2           3           0          2              9           0

Hi, I want to plot the residuals of a least-squares regression. plot(lm(y~x), which=1) does this, but it plots the y-axis of my data on the x-axis of the residuals plot. That is, it plots the residual for each y-value in the data. Can I instead use the x-axis of my data as the x-axis of the residuals plot, showing the residual for a given x? Thanks!

Hi everybody. I have a xen full virtualized guest running with 32 bit WIN 2003 Enterprise edition with 8 GB RAM assigned to it, but when the Virtual Machine starts only recognize 3,75 GB. I Have edit boot.ini with /PAE switch but still don't work. In addition,when i set pae value = 1 in the guest config file, the system gave me a blue screen after the windows splash screen. Kind regards

Hello, I have a centos 5.2 core 2 duo 3.0 GHZ with 2 GB ram which is working as a Virtual machine. i've just upgraded the hosting physical server from 32 GB to 64 GB of ram. which in turn, would require me to upgrade the VM to 8 GB. this is a 32 bit centos installation, would the system recognize and use the 8 GB? the option of using a 64 bit centos isnt possible. So i'm turning to you

we have CENTOS 4.7 (X86) on DELL server, I already put 32 GB RAM on it. I can use "top" or "free" to check memory and it did show 32 GB. I check REDHAT site and found it say: The "SMP" kernel supports a maximum of 16GB of main memory. Systems with more than 16GB of main memory use the "Hugemem" kernel. I use "uname -r" to check kernel and it

Hi, I want to use xen 3.1 on debian 4.0 (etch) in order to have Win XP, OpenSolaris, FreeBSD, NetBSD as guest os. Could you tell me if tell following hardware will fit fore this purpose (system is used for development)? Intel Core 2 Duo E6600, 4 GB RAM, 4x WD 1600AAJS (RAID 0+1), ASUS EN7600 Top Silent/HTD It would also be interessting for me if it will sufficent work (preformance) if I do

I would like confirm one thing. Based on what I saw Redhat document before, look like CENTOS 5 (X86, 32 bits) only support 16 GB RAM. Is this correct? Thanks.

If anyone was using a bfe card and seeing interrupt storms when you attempted to bring the card up, this is the fix for you. The driver wasn't previously taking into account the fact that the chipset doesn't like addresses over the 1GB mark. If you'd like an even quicker fix, just add hw.mem = "1000M" to your loader.conf and reboot. :) Mike "Silby" Silbersack

Hi all, I'm on a Linux server with 48Gb RAM. I did the following: x <- big.matrix(nrow=20000,ncol=500000,type='short',init=0,dimnames=list(1:20000,1:500000)) #Gets around the 2^31 issue - yeah! in Unix, when I hit the "top" command, I see R is taking up about 18Gb RAM, even though the object x is 0 bytes in R. That's fine: that's how bigmemory is supposed to

Is there any real advantage to using 64 bit when I am right at the 4gb ram threshhold? Nice plans to add more ram. The machine will just be a backup machie (rsync). Thanks in advance. D

Is this a known bug? Suprisingly google didn't turn up much. I'm running DDR RAM and a AMD XP processor on CentOS 4.

Dear Sir/Madam Hi. I am a general paediatrician, and I have read *some* chapters of the following books(1-3). I think SPSS lacks some features that may be important in data analysis (for example: interval of correlation coefficient in bivariate normal distribution, PRESS, and MSPR in cross-validation). I am thinking about changing SPSS to R: 1. SPSS is very expensive for me to update.

Hi there I am new to R and would like to ask some questions which might not make perfect sense. Anyhow, here they are: 1) I would like very much to use R for processing some big data files (around 1.7 or more GB) for spatial analysis, wavelets, and power spectra estimation; is this possible with R? Within IDL, such a big data set seems to be tractable... 2) I have heard/read that R

Hi, I've installed CentOS5.2 on an INTEL Core 2 Duo (Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz), 4 GB RAM (MemTotal: 4072176 kB) and my system gets sevarel minutes to startup, specially on udev daemon. Once the system is UP, every command I run gets 100% CPU and every is very slowly at the point yum -y update never ends. The system installed by default this kernel 2.6.18-53.el5PAE.

Is there a way I can prevent processes from taking up all the ram then swap until the box crashes/freezes? I'm using IEs4Linux and the wineserver seems to start taking up RAM until my box dies, it happens slowly. I am able to kill the sucker now, but I'd like to not have to worry about that. sar -r 01:00:01 PM kbmemfree kbmemused %memused kbbuffers kbcached kbswpfree kbswpused

As part of carrying out a complicated maximum likelihood estimation, I am trying to learn to program likelihoods in R. I started with a simple probit model but am unable to get the code to work. Any help or suggestions are most welcome. I give my code below: ************************************ mlogl <- function(mu, y, X) { n <- nrow(X) zeta <- X%*%mu llik <- 0 for (i in 1:n) { if

I am trying to get R to run on a Red Hat 8 system, I am running R version 1.6.2 with Tcl/Tk version 8.3.5 installed. When I try to test R from the data_sets directory I get the error message; Error in firstlib(which.lib.loc, package) : Tcl/Tk support is not available on this system Error in fileBrowser(textToShow = "Choose one CDF file" , nSelect = 1, : tcl/tk library not available

Hello, I'm unsing Ubuntu 14.4 Server and samba 4.1.6-Ubuntu. Everything works great but I somehow fail to switch off the password complexity requirements. It is not unlikely that this is because I'm very unexperienced with Windows. I've heard that the password-settings are always a bit tricky and I did exactly what the windows-tutorials say. I've tried gpresult for
