search for: spatiotemporally

Hi, I'm trying to compute  the spatiotemporal correlation matrix by using Delta Kronecker products of spatial and temporal correlation matrix  in R, but didn't find any delta Kronecker's operator in R. The operators in matrix such as multiplication, addition, eigen values/vector and etc is easily to find and used. Could someone help me, please? Cheers. Firdaus

Hi all, I'm trying to visualize animal movement data characteristics spatiotemporally by overlaying many different histograms on a map. I want the histograms to be plotted at coordinates in the map that matches a region they describe. If I was just doing this once, I'd fiddle in Illustrator after R and avoid the headache. But I'll be doing it many many times so it...

R help, How would I input data, verify assumptions, and run a nested repeated measures ANOVA using R? I have STATION nested in SITE nested in BLOCK with measurements repeated for five YEARs. All are random variables and it's only slightly unbalanced. I'm trying to characterize spatiotemporal variation in stream habitat variables. Thanks for your help! Eric Merten

I have a data assimilation problem that might be amenable to the use of GAMS, but I am not sure how feasible it is to implement. I was told the R mailing list was a great resource. My observations are spatiotemporal salinity in the San Francisco Bay at a number of instruments over a few days. The thing that I want to fit is the initial condition for a salt transport model at the beginning of this

Hi, and sorry for asking such an unspecific question. Does anybody know of statistical / data mining methods that are available in R that are not in SAS ? With SAS I mean the SAS System Version 9.4 and SAS Enterprise Miner. I don't expect a complete list, just two or three examples or hints where and what to look for. I found some older comparisons, and the R methods mentioned there

Sense Networks is looking for a data scientist with a thorough background in applied statistics, data visualization and exploration. Our data are typically location-referenced so experience in working with spatial data is a great plus. Having worked with "big" data on multiple server architectures is another valuable asset. We are looking for candidates who pay attention to details but

Hi all, I have a file of average SWE observations for 40 years at over 4,000 points and am attempting to do a spatiotemporal analysis of the data using PCA, much like this paper did using snow depth: http://journals.ametsoc.org/doi/pdf/10.1175/1520-0442%281998%29011%3C0856%3ATCIRWS%3E2.0.CO%3B2 I have followed the code in the link below by my loadings are far too small (For example, the paper

R users, I have been trying to write a program in R that will extract rows from a data frame and combine the rows into a new smaller data frame while meeting several criteria. I would greatly appreciate any advice that could help me get started down the right path. What I want to do is to extract two rows WEEK (26 weeks total) from the data frame by sampling without replacement from the

Hi professors I'm finding the best package in R for manage a big database about vessels. I need to divided the travel of each boat into tracks. I have GPS points. I would join these points in a line on the map. I make that with the function "lines", but I can't divided by vessel or by track, I saw several packages, for tracking animals but they had specifically variables. And I
