Subject: [R] writing simple function through script
To: r-help@r-project.org
Message-ID: 001601c91348$4b505a20$[EMAIL PROTECTED
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$Qe)
return(Lgm)
}
After the execution of the script, when I call the function yo on
Its looking in environment(LgmFormula) for Xdata in order to evaluate
Xdata$Qe in the weights argument so just specify weights = Qe.
Alternately insert the following as the beginning of yo.
It creates a new local LgmFormula but with its environment set
to the current environment:
