Dear R-SIG-GEO list
I want to aggregate the mean value of points in a polygon using the over
function.
#Read the shapefile with the measurements
shapefilename -
paste(shapefiledir,shortNameIndicator,_,production.date,sep=)
point.shapefile - readShapePoints(paste(shapefilename,.shp,sep=))
Els, what being weighted by what exactly? Any chance you can illustrate
your problem by something we can reproduce?

Dear Edzer
I have a point shapefile containing values of vaccination coverage (Z)
estimated via a sample (SampleSize)
The aim is to obtain a weighted mean of vaccination coverage per admin unit
Below sample code
studyzone -
readShapePoly(paste(backgroundfilesdir,GDAM_studyzone.shp,sep=))
Dear Edze
Thanks for your help
Best regards
