[R] Error Calculating Mean

[Mike Nielsen]

I'd hazard a guess that data.linear$Weight may have a "Not Available"
data point (ie. missing data).

> f <- c(NA,rnorm(10))
> mode(f)
[1] "numeric"
> mean(f)
[1] NA

If you'd like to compute the mean anyway, you can use
> mean(f,na.rm=TRUE)
[1] 0.3433036
