But this is ofcourse not ideal. Is there a way to force spsample to
always sample from top left to bottom right?

found using this method, the results do not the same as meuse.grid.
Could you define not the same.

could you tell me the details?

Are there other ways?

You can use the xlim and ylim parameters in spplot to zoom in.

Hi list,
is there any way to draw a map with spplot() WITHOUT a legend?
By the way: is there any documentation available for the function
mapLegendGrob()? I mean besides
the usage and arguments section in the relevant help page. I'm sorry I can't
find it.
Thanks in
Hi,
Loading the meuse.grid dataset is done using:
data(meuse.grid)
to generate meuse.grid from meuse use something like:
data(meuse)
coordinates(meuse) = ~x+y
meuse_grid = spsample(meuse, type = regular, cellsize = c(40,40))
gridded(meuse_grid) = TRUE
cheers and good luck,
Paul

Hi,
If your object's points are regularly spaced and in a SpatialPoints
object, use:
gridded(myobj) = TRUE
Or you can from a data.frame with the coordinates and attributes to a
grid by:
coordinates(myobj) = ~x+y
gridded(myobj) = TRUE
or shorthand:
gridded(myobj) = ~x+y

Hi,
More in general you need to take a look at the sp-pacakge for Spatial
classes in R. Once your data is in these classes you can use spTransform
from the rgdal pacakge to perform the projection. spTransform uses the
proj4 library. You need to find the so called proj4 strings describing
ChinaBorder to statSpat with the 'panel'
argument of spplot.
Any idea about how to proceed ?
