saveAndromeda: Save Andromeda to file

In Andromeda: Asynchronous Disk-Based Representation of Massive Data

Save Andromeda to file

Description

Saves the Andromeda object in a zipped file. Note that by default the Andromeda object is automatically closed by saving it to disk. This is due to a limitation of the underlying technology ('RSQLite'). To keep the connection open, use maintainConnection = TRUE. This will first create a temporary copy of the Andromeda object. Note that this can be substantially slower.

Usage

saveAndromeda(
  andromeda,
  fileName,
  maintainConnection = FALSE,
  overwrite = TRUE
)

Arguments

andromeda	An object of class Andromeda.
fileName	The path where the object will be written.
maintainConnection	Should the connection be maintained after saving? If FALSE, the Andromeda object will be invalid after this operation, but saving will be faster.
overwrite	If the file exists, should it be overwritten? If FALSE and the file exists, an error will be thrown.

Value

Returns no value. Executed for the side-effect of saving the object to disk.
