How to extend a slot of a class?
...-79.84 9.16 -79.84 9.17

..@ proj4string:Formal class 'CRS' [package "sp"] with 1 slots
.. .. ..@ projargs: chr NA
data is a data.frame including the information of long and lat location. I would like to have there a third information: time (but as POSIXct). Is there an elegant way to do this?
Best,
marco

I’d like to extract the area value so as to be able to use this value for further analysis. Here’s below what I get when I only type the name of the object:

Retrieving Vertices Coordinates from SpatialPolygons
Dear List,
I'm trying to use different R packages for my Teaching Assistantship
classes. And I cam out to an (apparently) very simple problem. I would
like to retrieve the vertices coordinate of a SpatialPolygon data. I
know this is stored in the "coords" slot, but I can't get access to
it! I tried to coerce the SpatialPolygon into a data.frame but it
doesn't work.
