illegal levels in yaImpute() / AsciiGridImpute()
I'm using randomForest in yaImpute to create a yai-type object which
associates "L" with landscape features. Then I use the sp() package to
impute L to a landscape consisting of four ascii files) I keep getting the
message "NA's generated due to illegal level(s)" when I do the imputation.
It's probably because one of the landscape features ("as", for

SVM
Hi All,
I fitted several classifiers in a two class problem. I then used the package 'yaImpute' - to apply my predictive models to asciigrids and thereby generate a
probability maps. So far I successfully used yaImpute to generate maps for
Random Forests, Classification trees, Generalized Linear Models (GLMs) and
Generalized Additive Models (GAMs). But when I try to use it to two other

AsciiGridPredict returns error in unionDataJoin
Dear list,
I am using AsciiGridPredict from the yaImpute package to make a spatial prediction of a randomForest model. When I call AsciiGirdPredict I am getting an error message, that I do not understand:
AsciiGridPredict(st.rf.fit, xlist, ylist, xtypes=NULL, rows=NULL, myPredFunc=NULL)
Rows per dot: 8 Rows to do: 884

Random Forest Imputations
Dear All,
I am not able to run the random forest with my dataset..
X<- 280 records with satellite data(28 columns) - B1min, b1max, b1std etc..
y<- 280 records with 3 columns - TotBasal Area, Stem density and Volume
yref <- y[1:230,] #Keeping 1st 230 records as reference records
want to set 0 to y values for records 231 to 280..
yimp <- y[231:280,] #records for which we want

knnFinder package
Dear all,
I have found some serious bugs in the knnFinder package (which supports
data structures and algorithms for both exact and approximate nearest
neighbor searching in arbitrarily high dimensions) that may trigger
segmentation faults.
I have fixed them but I had troubles to contact its maintainer Samuel E.
Kemp (previously with the University of Glamorgan, UK). Do someone know

k-nn hierarchical clustering
Hi there,
is there any R-function for k-nearest neighbour agglomerative hierarchical
clustering?
By this I mean standard agglomerative hierarchical clustering as in hclust
or agnes, but with the k-nearest neighbour distance between clusters used
on the higher levels where there are at least k>1 distances between two
clusters (single linkage is 1-nearest neighbour clustering)?
Best regards,
