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

...ying 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.

...ess) 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 the original rank, perturbed using the ratios of each of the newness and popularity to the highest values in the result set (i.e. there is no way to precalculate these at indexing time, alas). Currently fetching the document data for the results has become something of a bottleneck (typical searches my generate 50 - 500 matches, but some return more than 5000). Code is something like: ... print STDERR "Query = ", $q->get_description...

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.

...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

...ues, and I've specified the values in the config file, or I'm a user space program and provide these values over some X extension". This is even more effort now that modesetting is in the kernel (back when nvtv was written, it wasn't). Without this, you are pretty much stuck with precalculated modes. Which isn't optimal, because with small overscan the timing gets a bit fickle, and with larger overscan you get the ugly border, and every analog TV is different in that respect. - Dirk

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

...mum of 2 channels and 16 bit intermediate values (with block floating point, but still sucks for accuracy) that would require 32KB of intermediate storage. You'd still need to do in-place dot products of floor * residue on the fly or you need twice as much. 3) Window shapes need to be somewhat precalculated. Size depends on how much you mind approximation and playing tricks with table lookups. For an 8192 point window, I'd say 8KB is a reasonable ball park figure. That's already about 44KB. Given a processor like a Cirrus 7312 (very common), which has 48KB of internal SRAM, you'd be h...
