Hello,
and thank you for your answer.
I refer to the fact that in order to retrieve an array from R, this
has to be done element by element using the com server, since AB is
not accepting the R data type.
I wrote some AFL functions to do this, but I was wondering if the
plugin was somehow able to actually transfer data directly (which
would be much faster).
But if it using the com server I guess this is the only way.
Regarding the new implementation,do u mean that some AFL variable is
constantly update with its R "sister", without the need to tranfer
data back and forth?
Thanks
Ly
