For a file-backed big.matrix
object, flush()
forces
any modified information to be written to the file-backing.
1 | flush(con)

con |
a filebacked |
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.
1 2 3 4 | x <- big.matrix(nrow=3, ncol=3, backingfile='flushtest.bin',
descriptorfile='flushtest.desc', type='integer')
x[1,1] <- 0
flush(x)
