Hi all,
I have been attempting this repeated measure analysis
where correlation among observations (within each
subject) is spatial.
My command is:>fdat.lme1<-lme(Lint~Rep+Treatment,data=fdat,random=~1|fldPos,correlation=corLin(form=~lat+lon))
It is generating follwoing error:
Error in getCovariate.corSpatial(object, data = data)
:
Cannot have zero distances in "corSpatial"
first I thought that decimal values of
latitude/longitude are resulting in extremely small
values of distances, causing R to ignore it. So, I
scaled it up and made the coordinates integer values.
But I am still getting the same error.
Anyone can help? I don't know if you will need more
info to answer this question. Please let me know.
