Extracting results from Google Search
Dear list,
I have a long list of towns in Africa and would need to get their
geographical coordinates. The Google query [/TownName Country coordinates/]
works for most of the TownNames I have and give a nicely formatted Google
output (try Ingall Niger coordinates for an example). I would like to launch
a loop on the list of names I have and automatically extract the coordinates
given by Google. Does anyone knows how it can be done?
ex.
DB<-data.frame(town=c('Ingall', 'Dogondoutchi', 'Tera'),
country=rep('Niger'...

I want to do a line plot of the value of Amazon 'Sum' (in this case, 68348.4) for each of the 12 data frames. I've tried doing this as follows:

GWR Predictions' standard deviation
Dear all,
I would like to use a GWR model in order to spatially predict food
insecurity in Africa. I have a georeferenced village data-bases and I've run
a "classic" regression model (taking into account the spatial dependence of
the errors) that works fairly well for Niger that is a quite homogenous
country. Now, I would like to make the same thing for countries where it
should be some heterogeneity in the spatial process, so I think it is
essential to use a GWR.
The problem comes when I try to get the standard deviation of my predicted
values (not of my estimated...
