Hi all, I am interested in obtaining R code related to geographically weighted regression. In particular, I am interested in building geographically weighted Poisson GLMs. The model will contain categorical and continuous x independent variables, with interaction effects between categorical and continuous variables. Anybody have anything I can look at?...

Dear all, I have a dataset representing several geographical points (locations), each one having a specific value after performing a PCA. Now I'm trying to understand how to separately represent on a geographic map (of Europe) the pattern of PC1,2, ecc.with colors (e.g.heatmap) I have to add that the dataset includes relatively few points. Therefore,...

Dear R, I have a bunch of geographic locations specified by lat-long coordinates. What's an easy way to calculate geographic distance between any two points? OR, perhaps there is a function for calculating a distance matrix for K sites? Sincerely, Scott Chamberlain [[alternative HTML version deleted]]

i have two data frames. One data frame contains one column with the identificication number of a geographic place. The other columns are just some data about the corresponding geographic place. The other data frame also contains one column with the id number of a geographic place. the other columns of the second data frame is other data about the corresponding geographic place. I want to make one...

Hi R users I need the map of France?s ? communes ? (towns) to build a map Is there a way to get it? More generally: How to do to get the map of a country and its different geographical levels?

Hi, we all know that R is powerful in dealing with graphics. I am now trying to use R to show some geographic attributes for a specific geographic area on a graph. For example, if I would like to generate a graph showing the population densities (in terms of the intensity of colors) for Illinois State by zip codes. I did some research; and it seems that package "maptools" is relevant. But I hav...

Dear all, I'm performing RDA on plant presence/absence data, constrained by geographical locations. I'd like to constrain the RDA by the "extended matrix of geographical coordinates" -ie the matrix of geographical coordinates completed by adding all terms of a cubic trend surface regression- . This is the command I use (package vegan): >rda(Helling ~ x+y+x*y+...

Dear all, is it possible to perform logstic type of geographical weighted regression in R software? thanks in advance. robert. [[alternative HTML version deleted]]

I would like to create a geographical grid to have a sort of a reference grid for my georeferenced survey data. The grid should be in a xy format, wgs1984 with a 0.025 degree, alternatively 10km, resolution covering -14 to -24 S and 24 to -34 E (Zimbabwe). Additionally I need to be able to export it as a .dbf Hope someone can help...

Is there packaged code to convert geographical coordinates (e.g., longitude, latitude, elevation) to Cartesian coordinates in 3-space? I can see how to do this using 1. a spherical-to-Cartesian conversion like pracma::sph2cart(tpr) http://cran.r-project.org/web/packages/pracma/ 2. a geographical-to-spherical conversion. This seems to in...

...d with the dist() procedure in R) that DS> refers to pairs of points that are not neighbours. Deleeting is not ok; you should make them "large" in some way. I think you should just define your dissimilarities by *both* the "variability" (your current dist()) *and* the geographical distance, maybe giving much more weight to the geographical distance, something like D_{i,j} := d_{i,j} + w* d~(X_i, X_i) where d_{i,j} are your dist() or daisy() dissimilarities, 'w' is weight factor and d~(u,v) is e.g. the geodesic distance between u and v.

Let''s say I have two different geographic sites. They are pretty much identical ie. each site has a machine called web1 which is a web server, etc. Except there are couple site-specific settings ie. outgoing DNS servers are different, SSL certs are different etc. On the puppetmaster I can put in a file called e.g. /etc/sideid whic...

Dear list, I've drafted an article on installing geographic R packages on Linux computers and would appreciate any feedback. Is the following text correct, useful and future-proof?: R?s spatial packages can be installed from source on recent (since Ubuntu 19.04) versions of this popular operating system, once the appropriate repository has been set-up, m...

Hello, I want to crate a blanck geographical map showing continent boundary of region: latitude = -5:35 longitude = 35:100 If we create data like: lat= -5,0,5,10,...... long=35,40,45,50,......... Then how to map (long,lat) and create a map plot. Many thanks, Yogesh [[alternative HTML version deleted]]

Hi all, I am a very recent user of R. Mine is probably a basic question. I would like to know how do we create a certain set of points with geographic coordinates, between two endpoints. Please explain me how to do this using R. Which are the packages to be used for doing this. Thanks in advance, Ravichandra Mondreti.

...s is the case, 1) You do not need to sort anything. R has robust date-time manipulation and computation capabilities to handle dates and times, though in this case you only need dates. R knows all about how to order dates and times. 2) You do not have to physically group your records according to geographic location. R knows how to extract and manipulate groups without this; 3) And as all you need is a daily average, you do not need to worry about when days begin or end. If this is a reasonably accurate interpretation of what needs to be done, and your data are in a data frame called dat, then som...
