Hi all,
I'm doing some within-dataset model validation and would like to subset a
dataset 70/30 and fit a model to 70% of the data (the training data), then
validate it by predicting the remaining 30% (the testing data), and I would
like to do this split-sample validation 1000 times and average th
This function unfortunately does not work in 3d space.
Thoughts?

Your first description is correct with slight modification "compare point 1
to all the other points in that Cluster.Index and see if any of euclidean
distances are greater than 8; do this for each point (i.e. point 2, point
3) in that specific Cluster.Index (i.e. 45)"

So these two commands split the data frame by Cluster.Index and save them as a
list, Clusters and then compute distance matrices on each group and save them
as a list, Dists:
Clusters <- split(dta, dta$Cluster.Index)
Clusters
Dists <- lapply(Clusters, dist)

You should be able to process t

So it¹s now pretty clear that sasexport.get() gave each variable in the

Hello,
'points' is an R function (a closure) and either readOGR() or sub() or
both are expecting a vector. Use a different name, like pnts.
Hope this helps,

Until now, I have always source()d the .R file before running 'foo'.

Because the update of R is rather a trouble thing, i mean that you should have

Hi Frederico,
The kriging function seems to come from the kriging package (please give
also the package next time you ask a question), which I dont know. I can
therefore not tell you why it does not give you the correct result. But
R has a huge number of packages which can krige, and autoKrige
