[R] Bootstraps standard error

[danielepippo]

when I calculate the bootstrap standard errors the results are summarized in
a matrix with columns equal to the parameters of the model. In my case I
have a matrix like this:
            [,1]           [,2]         [,3]          [,4]         [,5]         
[,6]        [,7]      [,8]    [,9]

In the pdf file, where I've found the example, the matrix result has the
same equal columns, where the columns are relate to the nine parameters.
If I have to calculate the standard errors of each parameters, in the pdf
there is this:
At the end matrix results contains the bootstrap values of the parameters
and thus bootstrap standard errors can be obtained merely by calculating the
standard errors of the columns. 

How can I merely calculate thees standard errors?

The pdf is in the following file:

Thank you very much..
