Hello,
I have following problem with gOverlaps function:
I have two lines, A and B.
line A has 57 vertexes, all identical with vertexes of line B
yet, gOverlaps(A,B) gives FALSE
the code follows...
CooA # coordinates of line A
[,1] [,2]
[1,] -506157.4 -1122381
[2,] -506046.4
Would it be possible to provide your output in a form that we can read it?
I suggest dput().
Cheers,
Roman

Absolutely, sorry for that
dput(CooA)
structure(c(-506157.3827, -506046.35779, -506021.42681,

‘gOverlaps’ returns TRUE when the geometries share some but not
all interior points, and the intersection has the same dimension
as the geometries themselves.
Hence gOverlaps(A,A) == FALSE due to that 'but not all' part of the
documentation.

Thank you very much, problem solved.
