dear R users,
I need some help for multivariate analysis.
I have 2  anaesthetic treatment groups (20 patients/group) where I 
register heart frequency and pressure for 60 min (repeated measures 
every 5 minutes). I would like to perform a test to check if treatments 
are different in controlling freq and pressures during the anaesthesia, 
but i would like to have also an overall measure and not only multiple p 
for different time intervals. I also think I should choose a test in 
which time is meaningful since the measures are not simple repeated 
measurements but measurements taken at specific time points.
1 million dollar question.... how to do in R?
thanks in advance
