1. This is completely off topic. This is an R help list, not a
statistical advice list like stats.stackexchange.com.
2. I would strongly recommend that you abandon internet statistical
advice lists and seek local statistical help. You simply do not appear
to have sufficient statistical background to formulate an appropriate
analysis for what appears to be complex data. That you think you can
do so appears, itself, to be a measure of your statistical ignorance.*
Of course, that's just my perception...

perception of the state of your statistical knowledge based on your

plumbing, JAVA, ...

I've got a spreadsheet with one column listing frequencies in 5Hz bands and

to tight (referring to the tension of the reamer/chisel creating a cavity for
the hip replacement).

appreciate some advice from anyone with a handle on stats, could correlograms be
used in presenting this data? When working with a large number of bone samples,
can anyone recommend a good method of recognizing and mapping these changes?
