Dear List members,

 

I am running R 2.3.1 on a Windows 2000 machine. I have loaded the following packages: foreign, sp, maptools. I could load package shapefile as well, but this leads to conflicts with the packages sp and maptools.

 

I have the following question

 

I estimated by means of kde2d a 2-dimensional density based on a

sample of points. I passed this estimation to contour. I would like to 

export the result to a shapefile with lines. I have loaded foreign, sp 

and maptools. Can you give me a hint?

 

The result of contour is a list which has a vector for x and y and a

matrix for z mit dimension dim(x) X dim (y).

 

Thank's a lot for your feedbacks.
