Hi,
I've started to create the documentation of my package.
I've generate a pdf and the different html files from .Rd files.
However I don't know how to automatically generate the 00Index.html. Do I
have to write one in latex style and convert it or can I use the CONTENTS,
INDEX, or Rd files.
Package bootstrap is ORPHANED (that is, unsupported by anyone). Do try
package boot instead.
10 is a very small number of bootstrap replications: I do suggest you try
100 or more.

Could you please help me. How can I get indexes of matrix elements equal to the
