geographically weighted glm
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?

plotting principal components on geographic map
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, I

Geographic distance between lat-long points in R?
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

combining two data frames (different question)
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.

Graphically show population density for a specific geographic area using R
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

RDA and trend surface regression
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):

code to convert 3D geographical coordinates to Cartesian?
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 involv...

Cluster procedure using geographical neighborhood
...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.

OT : For the SQL gurus..
SQL help needed..
If I have a MySQL table with dialing codes and a corresponding
description (see below) and I want to lookup the best match for a phone
number.. What would the SQL look like to do it? or would it take more
than just SQL to get to the best result?
Thanks..
Later..

Specifying geographic related facts
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
which would uniquely identify a site ie. siteX or siteY.

Advice on article about installing R on Linux
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, meaning faster install times (only a

map geographical boundaries
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,

Creating a certain set of points with geographic coordinates between two endpoints
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,

calculate spatial distance
Hi,
I have a set of locations defined by longitude and latitude (in degrees),
and want to calculate the spatial (or geographic) distance among all
locations.
I did not find such a function in the spatial-related packages. (I *cannot*
use 'dist', as I have geographic, not cartesian coordinates).
thanks!
