Question: Interaction between two packages

Hello everybody,

* The following set of instructions returns me an error

restart:
with(Maplets[Examples]):
A := Matrix(2,2,[1,2,3,4]):
LinearAlgebra:-Transpose(A);

Error, Transpose is not a command in the Maplets:-Examples:-LinearAlgebra package

(it would be the same for any other command from the LinearAlgebra package)


* If I try 

restart:
with(Maplets[Examples]):
with(LinearAlgebra):
A := Matrix(2,2,[1,2,3,4]):
Transpose(A);

the answer is Transpose(...),  as if Transpose was an undefined function (no matter the order of the loading of the two packages)


* In Maplets[Examples] there is a subpackage named LinearAlgebra : could it be the reason of these observed behaviour ?
* Is there any way to fix that other than copying from Maplets[Examples] the only pieces of code I need avoiding thus its complete loading ?
* More generally : is it possible to load a package "partly" by discarding some of its subpackages ?

Thank you for your answers
