flush {bigmemory} | R Documentation |
For a file-backed big.matrix
object, flush()
forces
any modified information to be written to the file-backing.
flush(con)
con |
a filebacked big.matrix . |
This function flushes any modified data (in RAM) of a file-backed
big.matrix
to disk. This may be useful for
improving performance in cases where allowing the operating system to decide
on flushing creates a bottleneck (likely near the threshold of available RAM).
TRUE
or FALSE
(invisible), indicating whether or not the flush was successful.
x <- big.matrix(nrow=3, ncol=3, backingfile='flushtest.bin', descriptorfile='flushtest.desc', type='integer') x[1,1] <- 0 flush(x)
