A class interfacing FILEVECTOR C++ library 
for storage of and fast consecutive access to 
large data matrices in out-of-RAM disk mode 
with regulated cache size. Columns of matrix 
are accessible very quickly.
The 'filtered' 
class is based on 'base' class, see 
methods for that class for more details.

classes

a package providing interface to C++ FILEVECTOR library
        facilitating analysis of large (giga- to tera-bytes) matrices;
        matrix storage is organized in a way that either columns or
        rows are quickly accessible; primarily aimed to support
        genome-wide association analyzes e.g. using GenABEL and
        ProbABEL

databel_filtered_R-class function

Objects can be created by calls of the form <code>new("databel_filtered_R", baseobject)</code>.
FILEVECTOR data are stored using files of form BASE.fvi (index) and BASE.fvd (data). 
"baseobject" is either the BASE name, or object of class <code>"<links4class>databel_base_R</links4class>"</code>.
