Hi all,
 
I try to write a simple function in a script. The script is as follows
 
yo<-function(Xdata)
{
n<-length(Xdata[,1])
 
Lgm<-nls(formula=LgmFormula,
  data=Xdata,
  start=list(a=1500,b=0.1),weights=Xdata$Qe)
return(Lgm)
}
 
After the execution of the script, when I call the function yo on data
called NC60.DATA I get an error.
 
#yo(NC60.DATA)
Erreur dans eval(expr, envir, enclos) : objet "Xdata" not found
 
 
The object Xdata isn't found. Why?
Is that possible to debug a function with R?
 
Regards/Cordialement
