I'm trying to hunt down an appropriate kriging package for my specific application, and I was hoping someone on the R list might have some pointers -- I'm interested in performing kriging and related spatial interpolations with one of the R packages, but I need to be able to provide my own point-to-point distances (e.g. I do not want to use standard between point distances, as calculated

Hi, I am trying to learn to use RoR by making a simple social networking example. Given a user id, I am trying to make a query that finds all of the group that user belongs to but also rank the groups by one of the groups'' parameter like group.size. Pretend group.size is a number from 1-10 and is precalculated. Can I do this is one query? Here are the relationships I set up: class

Hello everyone Suppose I have an S3 class "dog" and a function plot.dog() which looks like this: plot.dog <- function(x,show.uncertainty, ...){ <do a simple plot> if (show.uncertainty){ <perform complicated combinatorial stuff that takes 20 minutes and superimpose the results on the simple plot> } } I think that it would be better to somehow

Hi, Suppose I have the following vector (data points): > x [1] 36.0 57.3 73.3 92.0 300.4 80.9 19.8 31.4 85.8 44.9 24.6 48.0 [13] 28.0 38.3 85.2 103.6 154.4 128.5 38.3 72.4 122.7 123.1 41.8 21.7 [25] 143.6 120.2 46.6 29.2 44.8 25.0 57.3 96.4 29.4 62.9 66.4 30.0 [37] 24.1 14.8 56.6 102.4 117.5 90.4 37.2 79.6 27.8 17.1 26.6 16.3 [49] 41.4 48.9 24.1

...print(cloud( z ~ x * y, data = q, type = c( 'p', 'h' ) , scales = list( arrows=FALSE ) , aspect = c( max(y)/max(x), max(z)/max(x) ) )) My questions: - Is there an easier way to tell that aspect ratio should be 1 on all dimensions, especially without the precalculations of max(...)? - "type = 'h'" does not work as I expected. What to do? - How can I get the labels of t into the graphic? Thanks Wolfram

We're using the Perl binding to access Xapian in a simple search of image metadata (title and keywords). Due to the specification for the search engine, by default we have to sort the results using a function of the search rank, age (well, newness) and popularity (rated by sales of the image). As a result, we have to fetch the complete result set and then calculate a new ranking based on

Hi All, I generate a pdf report that contains a table. The report is 14 pages, and it takes 20s to be rendered. Most of these 20s are spend in the render_on method. I wonder if it is possible to speed up that process? To create the report, I do the following: 1) Setup pdf layout: # Setup pdf layout pdf.select_font("Helvetica", { :encoding => "WinAnsiEncoding"})

virtio 1.0 doesn't use virtio_net_hdr anymore, and in fact, it's not really useful since virtio_net_hdr_mrg_rxbuf includes that as the first field anyway. Let's drop it, precalculate header len and store within vi instead. This way we can also remove struct skb_vnet_hdr. Signed-off-by: Michael S.

Suppose I have a CentOS 5.7 machine running the default Apache with no extra modules enabled, and with the "yum-updatesd" service running to pull down and install updates as soon as they become available from the repository. (Assume further the password is strong, etc.) On the other hand, suppose that as the admin, I'm not subscribed to any security alert mailing lists which send

...y with mgcv, I can halt the process (probably set "fit" to false) and then evaluate at a large number of arbitrary points, then replace the matrix X and continue on. I am also concerned whether this is hopeless in the sense that at the point in the algorithm where I might inject the new X precalculations might have been made using the old matrix X that would be hard to reverse. Can anyone give me some advice how to do this? Thanks, Eli

You can try nvtv (http://sourceforge.net/projects/nv-tv-out/). It bypasses X and modesetting and programs the Brooktree and CRTC directly. I've no

Hi R-list, I'd like to extract the psuedo model matrix (derivative of fitted values wrt the parameters) from an nls object. Any suggestions?

Hello, I have a matrix A with value varying from -1 to 1. I hope to use scaled color based on its value to produce an image of this matrix. Suppose I hope to label those data in [-1,-0.5] with blue, label those [-0.5,0.8] with light blue (tone is proportional to its value, e.g. rgb(1-tone, 1-tone, 1) where tone=abs(A)/0.5), and label those [0.8,1] with white. How can I use image() and rgb() to

Reinventing the wheel is fun. I've just got working a (sort of) complete implementation of vorbis using (very nearly) only the documentation. This was quite easy overall as the documentation is very comprehensive and clear. Nice job, whoever put it together! The one spot I had some trouble with was the low level residue decode. The pseudo code at
