[R-sig-Geo] sp basics !

gon for each element of the list ? -is there any distance method supported by a class "polygon" which can compute the distance to another geometry? thanks -- Dr Didier Leibovici http://www.nottingham.ac.uk/cgs/leibovici.shtml Centre for Geospatial Science Sir Clive

[R-sig-Geo] memory Usage setting

ich I don't really know if it took into account as the limit is greater than the physical RAM of 4GB. ...? would it be easier using Linux ? Thanks -- Dr Didier Leibovici http://www.nottingham.ac.uk/cgs/leibovici.shtml Centre for Geospatial Science Sir Clive Granger Building Univ

Re: [R-sig-Geo] plot.polylist polygon plot order

ge: 'plot.Map' is deprecated. Use 'plot.Spatial' instead. See help("Deprecated") and help("maptools-deprecated"). but I couldn't find plot.Spatial thanks again Didier Roger Bivand wrote: > On Tue, 21 Aug 2007, Didier Leibovici wrote: >

[R-sig-Geo] plot.polylist without borders or controlling the border width

Hi there, With plot.polylist is there a way of not drawing the "border" or controlling the width of the border in order to diminish the vision of horror when using a smaller colour range than the number of polygons and when you have quite a lot of polygons in your "shape". I am thinking as we

[R-sig-Geo] plotting shapefile facilities

Dear all, I read a shapefile using shapefiles package. Now I would I would like to go around the facilities to plot the shapefile. Is there any summary of all functionnalities related to "play" with a shapefile object? thanks -- Didier Leibovici Skype: didier_us166 [EMAIL
