Dear Contributors
sorry but the message was sent involuntary.
I am asking some advice on how to solve the following problem.
I have a list composed of 78 elements, each of which is a matrix of factors
and numbers, similar to the following

bank_name   date px_last_CIB       Q.Y    p_made p_for
1       CIB 10/02/06        1.33 p406-q406    406     406
2       CIB 10/23/06        1.28 p406-q406    406     406
3       CIB 11/22/06        1.28 p406-q406    406     406
4       CIB 10/02/06        1.35 p406-q107    406     107
5       CIB 10/23/06        1.32 p406-q107    406     107
6       CIB 11/22/06        1.32 p406-q107    406     107


Each of these matrixes changes for the column name bank_name and for the
suffix _CIB which reports the name as in bank_name. Moreover each matrix as
a different number of rows, so that I cannot transform it into a large
matrix.

I need to create a matrix made of the rows of each element of the list that
respect the criterium
that the column p_made is = to 406.
I need to pick each of the elements of each matrix that is contained in the
list elements, that satisfy this condition.

It seems difficult to me but perhaps is super easy.
Thanks for any help you can provide.

Francesca
