Dear list,
I am trying to convert a data matrix corresponding to a geostationary satellite
data to raster format or a format supported by GDAL. I have tried using HDF5
library with the following code:
n.col - 1701
n.row - 651
n.rec - n.col*n.row
zz - bzfile(file_to_convert.bz2,rb)

Hi,
You could also have a look at the R wiki, there is a part on spatial
data visualization using sp-classes:

Hello,
Filled contour is a really nice function, except when one use the
argument asp=1. In this case the legend height can be too large compared
to the image plot height.
Is there a way to control the legend height in filled.contour (eg fixing
somewhere a ylim=c(min value, max value) to

I've found the following error at importing a shp file
edited (deleting one line and creating another one) and saved with QGIS.
SHP files made (not edited) and saved with QGIS can be imported into R
with no problems.
I'm reporting to the QGIS list as well:
fl2 -
Additional information: it seems the error occurs with any polyline imported
from shp files,
not with straight lines.

Or you can define a panel function yourself along these lines:
spplot(grid_object, layer_to_plot,
panel = function(...) {
panel.gridplot(...) # Standard panel function for grids
sp.polygons(polygon_object) # Extra stuff on top
sp.points(point_object)
}

Hi Patrick,
Thanks for the code! My suggestion would be to use spplot instead of
filled.contour, this function is really made to display spatial data. It
works for grids, points and polygons and makes it really easy to combine
those in one plot. You need to put your data into the spatial R
