closefn.gds {gdsfmt} | R Documentation

## Close a GDS file

### Description

Close a CoreArray Genomic Data Structure (GDS) file.

### Usage

    closefn.gds(gdsfile)

### Arguments

`gdsfile` | an object of class `gds.class`, a GDS file

### Details

For better performance, data in a GDS file are usually cached in memory. Keep in mind that the new file may not actually be written to disk, until `closefn.gds` or `sync.gds` is called. Anyway, when R shuts down, all GDS files created or opened would be automatically closed.

### Value

None.
