[R-sig-eco] Plotting DBBMM over a map projection using movedata

[Levy, Yair]

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.

Cheers,

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
