how to image.plot a XY grid file into a lat-lon map
Hi All,
I have a netcdf gridded file with LCC projection. I can easily use
image.plot to visualize it. However, as the axises are in X,Y, not Lat and
Lon, I could not add state or country maps onto it (or lat lon information).
I do have a grid2d file that describes the lat and lon for each (X,Y) grid,
but the lat and lon are not regularly spaced, so I could not use image.plot.
Does anyone know

Hello asterisk-users,
I setup my asterisk to support several features like
automon,blindxfer,atxfer,parkcall etc. by using features.conf and the
global variable
DYNAMIC_FEATURES=automon#blindxfer#atxfer#parkcall#disconnect in
extension.conf. Every Dial() command in my diaplan has the appropriate
parameters out of {tTkWwW}.
For calls from my SIP phones everything works fine. Pressing #1 will

Extracting Krig results
I'm new at this, so please bear with me.
I am trying to get Krig (actually tps) results into a data frame at a
set of points.
Frankly, all I really need is to query the Krig on a specific XY pair
and return a result. I can carry the rest. I am using tps from the
fields package.
Here's the code I use to create the Krig object:

¿Qué hace as.numeric()?
En general lo que yo uso en esos casos es as.numeric(as.character(X))
No se los términos correctos pero los factores aunque se muestren con los
nombres de las diferentes clases, internamente son clases separadas que se
nombran como enteros por ejemplo del 1 al n de clases. Cuando usas
directamente as.nuemric sobre un factor, este toma los numeros de las
clases y no el valor de clase.

¿Qué hace as.numeric()?
Tranquilo que no te han hackeado tu "R"...
Simplemente que al importar tu CSV, no has indicado que los decimales son
las ",". Y ese campo lo importa como un character (un string). Y cuando lo
conviertes a numeric, el resultado es un tanto impredecible.
Si utilizas read.table para importar, simplemente incluye el parámetro
"dec" de esta forma "read.table(..... ,

Biglm source code alternatives (E.g. Call to Fortran)
Hi everyone,
I have been looking at the Bigglm (Basically does Generalised Linear Models
for big data under the Biglm package) command and I have done some profiling
on this code and found that to do a GLM on a 100mb file (9 million rows by 5
columns matrix(most of the numbers were either a 0,1 or 2 randomly
generated)) it took about 2 minutes on a linux machine with 8gb of RAM and 4
cores.
