Help with yaImpute
...resent in the predicted data
################################################################
The first six lines of the output file contain the header information for an ESRI ASCII grid and look like this
ncols 1564
nrows 1062
xllcorner -77876.53335875
yllcorner -3304144.3940076
cellsize 4.000718
NODATA_value -9999
Which is exactly the same as the input ascii grids used during the AsciiGridImpute command.
I was wondering if anyone on the R mailing list had ever come across this error and if so how did you correct it.
I am using R version 2.7.1 on Ubuntu 7.10
Many thanks for all your help.
Kind regar...
