In labbcb/Rqc: Quality Control Tool for High-Throughput Sequencing Data

Description Usage Arguments Value Note Author(s) Examples

This utility function can be used to save time on task that takes long time to complete. A Rda file are written on disk containing only objects setted to keep. If checkpoint function find related Rda file then this Rda will be loaded.

checkpoint(
  label,
  CODE,
  path = ".",
  overwrite = FALSE,
  verbose = FALSE,
  keep = NULL
)

`label`	name of this code, will create a Rda file with the same name.

`overwrite`	Rerun CODE and replace Rda file.
