Bootstrapping data with a regression model

Felipe Carrillo
Hello all:
Just wondering if I can get advice on what kind of
bootstrapping I should use when using a regression
model to estimate juvenile fish passage data. I use
rotary screw traps to do fish mark-recapture trials
and the efficiency of every trial is added to the
graph generating a different R-square and equation
everytime. I plot river flows along the X axis and %
trap efficiency along the Y axis. I have read about
the different bootstrapping approaches but I am not
sure how to do it..any help is appreciated.

   You might check out the the relevant web appendix by John Fox in the
Contributed Documentation section of CRAN:
