marshallable(...)

Arguments

x	A bigmemory::big.matrix object.
...	Not used.

Details

bigmemory::write.big.matrix() is used to produce a marshalled version of the original object. bigmemory::read.big.matrix() is used to reconstruct a version of the original object from the marshalled object.

A marshalled object as described in marshal().

Examples

if (requireNamespace("bigmemory", quietly = TRUE)) {
  library(bigmemory)
  
  x <- big.matrix(nrow = 3, ncol = 2, type = "double")
  x[] <- seq_along(x)
  
  ## Marshal
  x_ <- marshal(x)

  ## Unmarshal
  x2 <- unmarshal(x_)

  stopifnot(identical(x2[], x[]))
}
