[R] how to use sapply code

[Patrick Burns]

I believe you have received advice on how
to solve your problem already, this is just
to say why your 'sapply' call failed.

Your call to 'sapply' assumes that there is
a 'bt_m' argument to the function, which there
isn't.  Another problem might be that there
is an 'alp' argument but that is not given
in the 'sapply' call.
