Hi all,
I created a circular density estimate using package circular from bearings
(directions) from 0 to 360° assuming a von Mises distribution.

Dear list,
I am relatively new to linux and I am trying, unsuccesfully, to install
'rgdal' on a CentOS machine.
When I type in R:
$ install.packages('rgdal')
the installation stops with the following error:
checking for proj_api.h... no
configure: error: proj_api.h not found in standard or
Dear Edzer,
Thanks for the guide. I tried to use option nmax=100 and it works
perfectly. This implies I am using local interpolation of 100 observations
to predict a value at unknown locations rather than global interpolation
approach. I think this is better considering large size of my
Dear Community,
What are the ways to export a raster R object to a format that ArcGIS
will readily read? Can anyone suggest any code?
Thank you

I am getting error(as below) when trying to write seasonal ( quarterly)

My data details and sample data are below.
My code is

Dear list members!
Maybe, someone has a good idea how to speed up my raster-calculation, or knows
the right way how to deal with my „problem“.
For my master thesis, I use the focal-function and its focalWeight
(„raster“-package) for some raster calculations. For every cell of my map, I
sum up
Aseem provided me with some more info. writeRaster fails when the

The work around is to change these values using the setZ function.

Franz:
I'm not sure what you mean that you can't use focal_hpc for your
problem -- it seems like your problem would be fine for use with that
function -- its a bit easier to use rasterEngine, by the way. You can
use 1 input raster into your functions if you are using
rasterEngine, and you can
