Greetings,
 
I am revisiting some simulations that I ran about a year ago.  When I run the likfit function from geoR; a message is returned that reads "kappa not used for the spherical correlation function".  The simulations still run, but wasn't sure if this message indicates another problem that I need to be aware of.  I'm not using "fix.kappa=TRUE" or other references to kappa.  Below is the line in the code that is returning the message.  The "cressie" refers to the variofit function.
 
geo.reml<-likfit(data.geo,coords=coords.geo,data=y,cov.model="spherical",trend=~s2+s3+s4+t+ts2+ts3+ts4,method.lik="REML",ini=c(cressie[2]$cov.pars[1],cressie[2]$cov.pars[2]), messages=FALSE)#  
 
Is this anything to be concerned about?

Thank you,

Terry
