Dear list members,
I would like to look for attributes (e.g. distance from the shore) of spatial
points in other data sets (e.g. dist_shoreDF) after matching the points in
fishlocationDF and dist_shoreDF by their coordinates.
fishlocationDF$dist=dist_shoreDF$dist[match(dist_shoreDF$coordinates,
fishlocationDF$coordinates)] does not work
but illustrates what I am trying to do.
How can I deal with the two coordinates that every point has ? Would it be
possible to coerce both x and y-coordinate into one column in order in order to
apply the match() function ? Or is there a better way of approaching this ? I
would be grateful for a hint.
Thank you for your time.
Juliane
