How can one compose a plot, adding legend, title, and axis titles to a
plot of spatial object like a spatialpolygonsdataframe?
Any comment will be appreciated

Hi,
How can one coerce spatial point to spatial line?
I'm struggling to find a way of coerce a point SPDF object to Lines
based in a ID [TARGET_ID] field.
Any idea will be very welcome.
Formal class 'SpatialPointsDataFrame' [package sp] with 5 slots
..@ data
?

Thanks!
But by doing this
ltraj - Lines(sapply(split(traj_subam[c(LONGITUDE,LATITUDE)],
traj_subam$TARGET_ID), Line))
we get
Slot ID:
[1] NA
We are not holding the [Target_ID] column as ID ?

(TARGET_ID =
unique(traj_subam$TARGET_ID)), match.ID = T)
neither with match.ID = T or F

, wihout using
in-out, is there a way to overlap areas[1,] keeping in points
visible?

Hi,

Should I send a simple example?
Please do, either code for a provided data set, or code and a link to the URL
where the data set is available.

I'd like to plot a SPDF with two objects, one of them buffering the other
island. How can I set the island transparent?
Similarly, keeping the outer polygon only, how can the hole still
transparent?
Thanks in advance,
