Hello all,
I have two spatial points data frame df1 showing sample locations and df2
meteorological stations. I am interested in finding met stations closer to
the sample stations and creating a separate data frame with sample
locations and the nearest met station.
I calculated the distances

Hi,
To follow up on my last with an update. I modified the code a bit to run
with my data and set it on its way on our linux server. It seemed to be
running, and after the 3 days or so it took to go through all iterations,
it failed on me.
Here's the contents of the .Rout file:
R version
Hi,
I've been poking around igraph and spatgraphs but have not been able to
find a sufficiently simple example to make sense of.
Suppose I have three points A, B, and C.
The path from A to B is 3 units, from B to C is 4 units, and from A to C is
8 units.
Could someone provide a simple coding
I believe that you would find the tools in the spatstat package
(e.g. crossdist()) useful.
cheers,

Lyndon,
Please supply a self contained example (with generated data) with questions
like this. That is very easy to do in this case (create two overlapping
RasterLayer objects with different cell sizes).
This is not just to make it easier to answer your question. I is also the
way I would write
Hi Robert,
Many thanks for your quick answer on this. I will test this out.
Sorry, I should have re-provided the example I sent in my first email with
this. It has generated datasets, but I didn't put NA values in them, so it
was slightly different than what I ran with my actual data.
In any
Thiago,
What I am doing wrong?
1) you are not supplying a self-contained reproducible example (very easy
to do in this case).
2) This message:
Error in FUN(newX[, i], ...) : unused argument(s) (na.rm = TRUE)
will go away if you do:
fun - function(x, ...) {x - freq(x)}
3) But that won't fix
Navin,
I think you can achieve that like this:
mnd - apply(dist, 1, which.min)
cbind(coordinates(df1), coordinates(df2)[mnd, ])
