Load a log from disk — log

Loads a previously saved piplog from disk using the stamp package. Validates the loaded object and restores it to .piplogenv with a given name. If id lacks an extension, one is added based on the format parameter.

Usage

log_load(
  id,
  name = id,
  version = NULL,
  format = "qs2",
  overwrite = FALSE,
  verbose = TRUE,
  alias = NULL
)

Arguments

id: File identifier or path (extension optional).
name: Name to assign to the log in memory (default: id).
version: Optional version identifier or "available" to list versions. Passed to stamp::st_load(). Default loads the latest version.
format: File format (default: "qs2"). Used to add extension if id lacks one.
overwrite: Logical: whether to overwrite an existing log in memory with the same name (default: FALSE).
verbose: Logical: whether to announce loading progress (default: TRUE).
alias: Optional stamp alias to select which catalog/versions to use.

Value

The loaded piplog object (visibly), or if version = "available", a data.table of available versions with a vintage column.

Details

Use version = "available" to list all available versions of the log file without loading it.

Examples

if (FALSE) { # \dontrun{
log_load("results", name = "loaded_log")
log_load("results", version = "available")  # List versions
} # }
