by R  functions (i.e. predict.lm ) to calculate the statistic reported.  I
am not a programmer and studying the r code is extremely slow going.  I
have searched  r-project.org and all the function help files without
success. For example I have attempted to replicate by hand the se.fit
calculation from a lm object calculated by a call to the predict function
and have not been able to reproduce the results. 

Thanks,
