Save R Object using pigz compression

Description

Save writes an external representation of R objects to the specified file using pigz parallel implementation compression (http://www.zlib.net/pigz/).

Usage

save_pigz(
  ...,
  list = character(),
  output_file_path,
  cores_utilisation = "auto",
  compression_level = 1L,
  precheck = TRUE,
  envir = parent.frame(),
  eval_promises = TRUE
)

Arguments

`...`	Names of the objects to be saved (as symbols or character strings).
`list`	character expected. A vector containing the names of objects to be saved.
`output_file_path`	character expected. Path name of the file where data will be saved.
`cores_utilisation`	character or integer expected. Percentage of cores to use to compress (value inferior or equal to 1 expected). Use "auto" for automatic management (number of cores minus 1).
`compression_level`	integer expected. Compression level, 0 for no compression to 9 (maximum).
`precheck`	logical expected. Should the existence of the objects be checked before starting to.
`envir`	Environment to search for objects to be saved.
`eval_promises`	logical expected. Should objects which are promises be forced before saving?
