[R] function that join my model & these coefficients

[Jeff Newmiller]

You should study the theory of regression before proceeding, since the chance of obtaining a significant (useful) result with 400 inputs is negligible.

You should also read the help files for the functions you are using (e.g. ?lm), which in this case mention the coef() function in the See Also section.
