Attach a big.matrix (typically used for all-by-all blast distances)

Description

These are file based matrices that are not loaded into memory. If bigmat="mybigmat" there should be a big.matrix description file called file.path(fcconfig$bigmatrixdir,'mybigmat.desc'). If passed a name ending in '.ff', the corresponding ff object is attached.

Usage

fc_attach_bigmat(bigmat, envir = NULL, force = FALSE)

Arguments

bigmat	Name of big matrix object (which should match file on disk).
envir	The environment in which the resultant object should be created.
force	Whether to overwrite an existing object of the same name

Value

A big.matrix or ff object.
