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
ToDo:
..............................................................................................................
Done: Error in unionDataJoin(m1, m2) :
row names are requried within all input matrices
In addition: Warning message:
In AsciiGridImpute(object, xfiles, outfiles, xtypes = xtypes, lon = lon, :
NA's generated due to illegal level(s).
Does someone know what the error means and how I can solve this problem?
Thank you very much in advance,
Frauke
