Dear Allin
Ok well noted. Think i must change the doc.
I wonder why the following command is not executed
# building a matrix of equations coefficients without constant
matrix Z[1,]=transp(logement.$coeff[2:5])
matrix Z[2,]=transp(transport.$coeff[2:5])
matrix Z[3,]=transp(composite.$coeff[2:5])
print Z
it produces :
composite saved
# construction d'une matrice des coefficients hors constante pour calcul des
élasticités
? matrix Z[1,]=transp(logement.$coeff[2:5])
matrix Z[1,]=transp(logement.$coeff[2
Expected ')' but
found '['
Error executing script: halting
matrix Z[1,]=transp(logement.$coeff[2:5])
thanx again
Franck
