...diagonal matrix,I have tried to transform col1 and col2 to rowindex and colindex ,but I don't know how to generate matrix by its value's index 2. As you see, the number of 2353 corresponding to other ids in col2 is 53,however,the number of 2409 corresponding to other ids in col2 is 52 and 2500 corresponding to 51 values and so on,so it is hard to use matrix() to generate it id1 id2 value 2353 2353 0.096313 2353 2409 0.301773 2353 2500 0.169518 2353 2598 0.11274 2353 2610 0.107414 2353 2300 0.034492 2353 2507 0.037521 2353 2530 0.064125 2353 2327 0.029259 2353 2389 0...

My main concern is speed of large dense matrix multiplication.

Dear all, I have a large matrix with about 2500 variables, and 100 rows. I would like to calculate the means of the every 10 variables starting from 1:2500 and saving the results as a vector or matrix. How can I do that? Alternatively, How can I create 250 subset matrices in the order of variables 1:2500 in groups of 10 from the single matrix...

Hi all, I tried to produce some kriged surfaces with geoR (latest version). The size of the grid should be around 900 x 650 cells (what I find is not a very big grid), and the number of points is around 2500. The command krige.conv stopped after arround 5 min saying it can not allocate a vector with around 1.5 billion units. Sounds reasonable. Is there a workaround? How would I partition the map into several smaller pieces to krige them separately and retain the smooth transitions from one part to...

Hi all, I have just begun to use R and am hoping to receive some advice about the problem I need to solve. I have a file containing xy points that I need to find all significant clusters and write each of their xy coordinates to file(total points ~ 75000 and sig. cluster = 2500 points. I want to use a euclidean distance threshold to determine if a point belongs to a cluster. My initial thought is to take a random (seed) point and write a region growing method to determine how many points belong to the cluster (basically, add to the cluster all points that are within the...

...ze and mass are continuous ratio data to all intents and purposes. The data actually represents sieving of sand where $size is sieve aperture and where $mass is the amount remaining on the sieve. So if I sieve 100g of sand through increasingly fine sieves nothing remains on the coarsest sieve say 2500 microns. Between 2000 and 2500 microns there is 0.2g remining on the 2000micron sieve etc. as per the data supplied. size, mass 2500, 0 2000, 0.2 1700, 1.8 1400, 5 1000, 13 800, 40 600, 20 300, 15 180, 3 <180, 2 The data here I have made up for simplicity.
