Description

Write the data cached in memory to disk.

Usage

sync.gds(gdsfile)

Arguments

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.
