   Dear List
   I am using R with mcgv package to model spatial variation in density estimates of dorcas gazelle in Sinai. I have 59 points of data and 4 explanatory variables(distance from mountain edge, camel presence, Latitude & Longitude). I want to test the model fir via bootstraping. I have used the jacknife bootstraping but it have the limitation of allowing only 58 trials. I tried to use the bootstrap function in R but I couldn;t understand the help file description. Please forgive my novice with such advance statistics since I am a biologist.
   I would appreciate any help on advicing on how to use the bootstrap function in R.
   Thanks in advance

Just a off-topic comment.  With only 59 points but 4 variables, you
are stretched very very thin using a nonparametric method.  Bootstrap
isn't going to bring in more information.

If I were you, I would try to find some parametric model to fit to the
data.
