Jim,
your percentage variable is read as a factor; just check:
> class(tx3_sp$CK_PCT)
this is because R does not understand % symbols (unless you tell it).
Convert it to numeric by
> tx3_sp$CK_PCTN = as.numeric(unlist(strsplit(tx3_sp$CK_PCT,"%")))
and use spplot on the new variable. The as.

Hi Jin, you're not the first to run into this one; read the fit.lmc

fit.lmc fits partial sill matrices that may have perfect correlation
among variables. To avoid so, you could instead of

I am running OCK for a number of datasets. The codes worked for the first five
datasets and then I got an error message:

Is there any way to convert from tessellation to sp classes like

Dear Virgilio,
I think you're right. Unfortunately, I am not familiar enough with the
analysis of spatial data to avoid such conflict.
Do you know wath function I should use to generate contour before
conversion.
I tried contour but it didn't work:

First of all, I'd like to wish you a happy new year, with many nice

I have a graphical problem when plotting kriging results. I first want
to see results on a plot and, secondary, I'd like to add contour lines
to the plot. The problem is that lines are at a wrong pl
