Hi Stacey,
How we meet again... You could re-project your data by using package sp with
function:
spTransform
The only thing you need is to define the coordinate reference system of your
input spatial object when creating it using the input "projection-less"
shapefile and then to define the coordinate reference system of the data to
export/plot/project.

Onderwerp: [R-sig-eco] Plotting DBBMM over a map projection using movedata
I have been using R to calculate KUD and MCP estimation for a series of tracks
for fish in a reef system. I have successfully calculated these using
adehabitat and the move package in R, but I am having difficulty plotting them
over a map projection.
I have been able to plot tracks using ggplot for geom_line but there is no way
for ggplot to handle movedata DBBMM stack contours and every time I split the
stack to try and plot a single individual it doesn't recognize the class.
I need something for geo-referencing and I know there are other methods such as
transfering shapefiles for ArcGIS but every time I save a shapefile the
projection doesn't export so the plots do not line up.
I attached the DBBMM plots for each individual along with the projected map
image I am trying to overlay the plots on. I can give you the code I have been
working with as well if anyone has had an easier time accomplishing what I am
attempting.
Thanks,
Stacy
