[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
