Question about error of "non-numeric argument to binary operator"
I have been trying to do a nls model and gives me the error of a nonnumeric
argument
table(file="c:/tt2.txt",header=T)
> fit.model <- nls(TT~60*(1+alpha*(v/c)^beta),data=tt2, start=list(alpha=1,
beta=3, v=1000))
Error in v/c : non-numeric argument to binary operator
> is.numeric(tt2)
[1] FALSE
> is.character(tt2)
[1] FALSE
> as.numeric(tt2)
Error: (list)
