hi, hi all,
There are several methods to analyse two (e.g. coinertia, procuste)
or K tables (e.g. statis, mfa, gpa, etc.) in the packages ade4, FactoMiner, etc.
Otherwise analyses on instrumental variables can be an interesting way to
explore your dataset (e.g. within/between analyses, etc.)

Yes there is: statis() in the ade4 package is probably what you want. In
short, it does a k-table analysis that will give you a common
ordination/position. It also shows how each time-set deviate
Dear all:
Subjects were measured two times (t1 and t2) on different variables (v1 ...
vn).
Between t1 and t2 there was an experimental manipulation. I computed two PCAs
for time-points t1 and t2.
Is it possible to combine both PCAs in order to get only one set of
eigenvectors? Due to the exp
