search for: decended

First, my site will be down December 27-28 because of a network upgrade at Penn. It will also be down at least one day before that, while I upgrade the operating system. (And another day some time in January because of a planned power outage.) Second, I have replaced the search engine in my R site: http://finzi.psych.upenn.edu/ I am now using Namazu instead of HtDig. The direct link to the

I've got a matrix with 2 columns and n rows. I need to sort it first by the values in column 1 ascending. Then for values which are the same in column 1, sort by column 2 decending. For example: 2 .5 1 .3 1 .5 3 .2 Goes to: 1 .5 1 .3 2 .5 3 .2 This is easy to do in spreadsheet programs but I can't seem to work out how to do it in R and haven't been able to find a solution anywhere.

Hello 'R' Users, I am very new on 'R', so excuse me if I ask something wrong. I have ASCII data and the colums of the data are looks like :- !------------------------- time,yr,mo,dy,hr,min,sec,lat,lon,ht,co2obs,sigma,co2model -- - -- !---------------------------- Each column has data value. Now I want to produce 2-d color maps, for example the plot should look like :- on

Clearly, I don't understand what order() is doing and as ususl the help for order seems to only confuse me more. For some reason I just don't follow the examples there. I must be missing something about the data frame sort there but what? I originally wanted to reverse-order my data frame df1 (see below) by aa (a factor) but since this was not working I decided to simplify and order by

I have a list of names and prices from a database to display on a webpage. I would like to allow the user to be able to display those items either alphabetically or by price (decending or ascending.) I would also like the user to be able to list items with a certain price range of their choosing also. How can I do this in Rails? Thanks! -- Posted via http://www.ruby-forum.com/.

When working in development mode, do non-AR models reload? I''m not seeing changes I make reflected in the app unless I restart webrick, so I''m assuming the answer is no. How would get these model objects to reload just as their AR decendant brothers and sisters do? --Ryan

Hello, there is a small typo in the vorbis-tools.spec file which prevents the successfull build of rpms: # rpm -ta vorbis-tools-1.0beta4.tar.gz %changelog not in decending chronological order The necessary change is: %changelog -* Mon Jan 22 2000 Jack Moffitt <jack@icecast.org> +* Mon Jan 22 2001 Jack Moffitt <jack@icecast.org> - updated for prebeta4 builds * Sun Oct 29 2000

Hi, I have a question that I haven't been able to answer from the docs. I wondered if someone out there has tried to do what I would like to attempt. On our server, we have mapped a share called wrkgrps to drive G: Users then have various directories under drive G: which correspond with their department, i.e. accounts, personnel, etc. Each of these directories has a share which I have

Hello, When I plot or look at the error rate vector for a random forest (rf$err.rate) it looks like a descending function except for a few first points of the vector with error rates values lower(sometimes much lower) than the general level of error rates for a forest with such number of trees when the error rates stop descending. Does it mean that there is a tree(s) (that is built the first in

Dear 'HTH' R friends I have a small dataframe as given below. I need to sort this database based on date in a decending order. I am not sure whether I have defined the date column in a proper format. mydat<-data.frame(date = (c("1/31/2010", "2/28/2010", "3/31/2010", "4/30/2010", "5/31/2010", "6/30/2010",

Hi All, I'm looking for ways to compute aggregate statistics (with the aggregate function) but with an option for sorting and selecting a subset of the data frame. For example, I have would like to turn this : aggregate(myDataframe$TargetValue,list(SomeFactor = myDataframe$SomeFactor),mean) into something like aggregate(myDataframe$TargetValue,list(SomeFactor =

We finally flipped the switch on one of our ZFS-based servers, with approximately 1TB of 2.8TB (3 stripes of 950MB or so, each of which is a RAID5 volume on the adaptec card). We have snapshots every 4 hours for the first few days. If you add up the snapshot references it appears somewhat high versus daily use (mostly mail boxes, spam, etc changing), but say an aggregate of no more than 400+MB a

I have moved a Samba installation from an old samba 2.2.8a (on a 2.4.21 kernel) to a new server running Samba 3.0.10 on a SuSE 9.2 (kernel 2.6.8) and I now have a problem using the (same) shares from client W2K machines. When I open "My Computer" window on a client, the drives are marked by a red cross, as if they were disconnected, and the disksize is zero. I can decend into the

Greetings. I'm trying to determine whether to use rpart or randomForest for a classification tree. Has anybody tested efficacy formally? I've run both and the confusion matrix for rf beats rpart. I've looking at the rf help page and am unable to figure out how to extract the tree. But more than that I'm looking for a more comprehensive user's guide for randomForest including

ZFS documentation lists snapshot limits on any single file system in a pool at 2**48 snaps, and that seems to logically imply that a snap on a file system does not require an update to the pool?s currently active uberblock. That is to say, that if we take a snapshot of a file system in a pool, and then make any changes to that file system, the copy on write behavior induced by the changes will

First, I have only played with Prototype for about a month, so I don''t know it well. Second, I am more of a server-side programmer than a client-side programmer. In my page, I have a div that appears as a result of a link mouseover event. This div is nested within another div that houses everything (id = ''menuContainer''). I want the resulting div (which is a submenu)

Sorry for being a bit of a newbie here but I find the docs or README for downloading the G.729 codec from Digium are not as detailed as I would like or just don't really break down the different versions to a point that I am clear on which one to grab. The choices for 32bit are: drwxr-xr-x 3 0 0 4096 Dec 05 00:21 athlon-xp drwxr-xr-x 3 0 0 4096 Dec

I can never remember how to use "order" to sort the rows of a data frame, so like any good, lazy programmer, I decided to write my own function. The idea is to specify a data.frame and a one-sided formula with +/- indicating ascending/descending. For example: sort.data.frame(~ +nitro -Variety, Oats) Since sorting of a data.frame is an oft-asked question on this list, I am posting

...ain etc). In a nutshell, when i double-click a file such as: \\server\share\x.txt in explorer, it gives a "The directory name is invalid error". I can, though, do a sendto->notepad and it works fine. I also can file|open->file in notepad. This error does not occur when the file is decended another directory ie: \\server\share\directory\x.txt. This only happens with win2k clients, 98 works fine in both cases, and i have no NT workstation machines to try. Is this another simple win2k hates the world case? Any loopholes to work around this? I am assuming samba 2.2x fixes this. For a p...
