All,
I have been using a data set to build pls models for three different soil
properties. Two of the three models run fine; however I receive the following
error for the final model.
> libs.IC.cal <- mvr(libs.IC.fmla, data = libsdata.cond.cal,
> ncomp=20,validation = "LOO", method = "oscorespls")
Error in colMeans(x, n, prod(dn), na.rm) :
'x' must be numeric
There are many "0" for this soil property. Could this cause the error?
Best,
Ross
