The code below is a small reproducible example of a much larger problem. While the script below works, it is really slow on the true dataset with many more rows and columns. I'm hoping to get the same result to examp, but with significant time savings. The example below is setting up a data.frame for an ensuing regression analysis. The purpose of the script below is to appends columns to

I keep expecting R to have something analogous to the =count function in Excel, but I can't find anything. I simply want to count the data for a given category. I've been using the ddply() function in the plyr package to summarize means and st dev of my data, with this code: ddply(NZ_Conifers,.(ElevCat, DataSource, SizeClass), summarise, avgDensity=mean(Density),

Hello, I have a data set that needs to be combined so that rows are summed by a group based on a certain variable. I'm pretty sure rowsum() or rowsums() can do this but it's difficult for me to figure out how it will work for my data based on the examples I've read. My data are structured like this: Plot SizeClass Stems 12 Class3 1 12 Class4

I planned using ifmember.exe from Windows 2000 resource kit to map the right drive-mappings to the right shares with logon-scripts. Unfortunately it seems as ifmember simply doesnt report the right groups for the users. Even tho "id user1" shows the right groups; "uid=2082(user1) gid=1002(Group1)roups=1002(Group1),545(Users),1000(Group0)", User is a member of group

I have data that looks like this: > df1 group id 1 red A 2 red B 3 red C 4 blue D 5 blue E 6 blue F I want a list of the groups containing vectors with the ids. I am avoiding subset(), as it is only recommended for interactive use. Here's what I have so far: df1 <- data.frame(group=c("red", "red", "red", "blue",

I fired up the debugger and watched the code happen tonight. The problem occurs if the config.action_controller.perform_caching = true in your environment. It''s not set to true in development but it is set to true in production and staging. The problem occurs not in my controllers but in sweeping.rb (part of rails). Rails calls this code for every controller which was instantiated in

We are running Suse Linux 8.2 with Samba 3.0.0.1 and Cups as our print server on a network with windows 98 and 2000 clients and HP1300, 2100, 2200 and 4050 printers. We are experiencing an intermitant error whereby the printer on the client machine will set itself to work off line and sometimes freeze up the pc when an attempt is made to print from it. This error does not happen in any consistant

Hi all, I was wondering if some one could give me ideas on how I can troubleshoot the following problem; log files to check, etc? I?m running CentOS 7.2.1511 with KDE. I login and open 1 or 2 shells. If I leave the system alone for about 15 minutes and then try to open another shell I get the error; Could not launch terminal client At this time, upon clicking on the lower left hand menu, the

I have had terrible luck trying to find a ppd that works correctly for both win9x clients and winNT/2000/XP at the same time. The CUPS method is to find one ppd that works for all and I have tried several: those at linuxprinting.org, hp's sourceforge site, vendor winNT ppds (docs suggest these), and vendor win98 ppds. I have tried filtering PJL and not filtering PJL. I have the stock

Hello, I am having a frustrating time trying to get bridge networking working. I''ve gone over the Wiki page on the topic, a few of the howtoforge pages and everything that I am doing is failing utterly. What I want to achieve is to have Dom0 be a stub running two DomUs. One DomU being a router/firewall and the other being the rest of what is on the current machine.

Hi all, This has been very frustrating for me trying to get this acts_as_ferret working well on a Fedora box. On my mac it works great, no problems with locale, but when I put the code live on my Fedora server, it complains about the locale setting (Error occured at <analysis.c>:498 Error: exception 2 not handled: Error decoding input string. Check that you have the locale set

Dear Colleagues, Occasionally I deal with computer-generated (i.e., websurvey) data files that haven't quite worked correctly. When I try to read the data into R, I get something like this: Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : line 26 did not have 648 elements ...is there any way to get R to tell me how many elements line 26 *did* have? That

Hello everyone. Im not sure what is wrong here, but I cant seem to figure out why one of my users cannot access a share on a file server that we are running here. Running on RH 8.0, samba 2.2.7a. (Planning on upgrading eventually) Anyway, one user for some reason, cannot access the share through his network neighborhood icon. Here is the share info: [AdminDirectory] comment =

At this point, I've been through 4 AMD64 motherboards. Commonly, AE_BAD_CHARACTER stops ACPI (or apic?) from figuring out the system --- this has happened on 3 out of four boards. On this latest board, it can turn off APIC. If I do that, FreeBSD hangs after detecting the disks. The only "wrong" thing on the screen is module_register_init: MOD_LOAD (amr_linux,

[Sorry if this is off-topic for this list, please advise me if there''s a better place to ask this] I have an embeded motherboard with 4 natsemi (DP8315) ethernet chips. I''m running a 2.6.9 kernel (I''ve tried 2.6.11 too) and a very minimal Slackware distribution. Now about the problem: The network interfaces seem to NOT transmit anything when the interface is

Hello all. I am having a hell of a problem and it''s driving me nuts. I get the following error (undefined method `controller_name'' for nil:NilClass): but only when config.action_controller.perform_caching = true I googled around some and found this thread http://groups.google.com/group/communityengine/browse_thread/thread/b84154e5228bf9f3which suggests it may be a conflict with

Greetings all, (Hopefully this won''t be a HTML mail.) I''ve picked up puppet as a tool to manage a fairly small network of RHEL servers, and I''m really liking what I see so far. However, I''m having a pile of trouble with a class definition for a yum controller: # $Id$ class yum-rhel5 { file { "/etc/yum.conf": mode => 644,

I''m having a difficult time with a dependency issue. Basically, I want to be able to call a defined type, but it''s not working out so far. I have my manifests setup like this: init.pp: class foo { .... } bar.pp: class foo::bar { include foo package{ "test": ensure => running, notify =>

I am using RMagick in my app and am having problems in deployment. The deployment machine (Fedora Core 5) can''t find RMagick unless I change the "require" syntax from that used on the dev machine (OS X). And the dev machine doesn''t like the syntax that works on the deployment server! To wit: [OS X] $ script/console Loading development environment. >> require_gem

Hi, Running CentOS5 with SpamAssassin v3.3.1-2.el5 installed via yum I remember getting this error a while ago, and it was fixed, but now it's happening again: Subroutine Net::DNS::Resolver::Base::AF_INET6 redefined at /usr/lib/perl5/5.8.8/Exporter.pm line 65. ?at /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/Net/DNS/Resolver/Base.pm line 65 The results I get from Google
