Thanks to the help of people from this forum I was able to bootstrap my data
and then apply a model to it.  Thanks for all your help.  

 

Everything worked out well, but I am having a difficult time getting the new
parameter values.  I bootstrapped the data 300 times and I want to get the
300 sets of parameter estimates and plot them in Excel.      

 

Here is my code:  

 

par<-list(Linf=700, K=0.3, to=-0.1)                            #starting
values for parameter estimates

vb<-nls(length~Linf*(1-exp(-K*(age-to))), start=par, data=small)     #von
Bertalanffy growth mode

boo<- nlsBoot(vb, niter=300)                                     #This
bootstraps my data 300 times and applies the growth model

 

I can get R to plot the 300 parameter estimates if I do the following
function: 

plot(boo)

 

However, I have tried different print function options but have not had any
luck getting the 300 parameter estimates.  Any advice would be greatly
appreciated.  

 

Thanks.  

 

Mike
