Documentation for `make.ds.analysis`

[erex]

One thing to correct

The first example under Examples comment says analysis with truncation of 5% of the data. However, help states that truncation uses absolute distance. Similarly, the actual code for the first example has 500 for the value of the truncation argument.

One thing to amplify

The Details section of the documentation is devoted exclusively to the group.strata argument and its behaviour. I can't figure out how the control.opts argument behaves; what might that list contain? Can performance of the slsqp optimiser be compared with the previous default optimiser via this route?
