[R-sig-eco] R not plotting all my GPS points - spatial data

[Isabella Mandl]

Dear all,
again possibly a rather simplistic question - but I can't figure it out!
I've been calculating (and plotting) kernel home ranges using adehabitatHR,
all of which worked fine, but I am currently trying to plot additional
points into the home range outline to show the specific locations of
behaviours of interest.
For this I have created 3-4 subsets from the original data, converted them
into coordinates as well and then tried to plot them on the kernel outline.
It works, but it only displays some of the points, for example, seven out
of nine...?
Investigating the structure of the point data, all is fine, the points
exist and are projected correctly.

Does anybody maybe know why R could be doing this?
I'd be grateful for any hints.

Regards,
Isabella
