Hello,

I have weight and wing length data of 5 kinds of birds (B1 to B5).
Weight data (predictor) and wing data (response) were used to generated a
simple regression.
(using lm)

Now some weight data are found but without wing data (B6, B7).
I want to use the generated simple regression to produce wing data of B6
and B7 by their weight data.
Please kindly advise R code to carry it out.
Thank you.

Elaine
