snapshotImpl: Internal Snapshot Implementation

In rstudio/packrat: A Dependency Management System for Projects and their R Package Dependencies

Internal Snapshot Implementation

Description

This is the internal implementation for snapshot. Most users should prefer calling snapshot.

Usage

.snapshotImpl(
  project,
  available = NULL,
  lib.loc = libDir(project),
  dry.run = FALSE,
  ignore.stale = FALSE,
  prompt = interactive(),
  auto.snapshot = FALSE,
  verbose = TRUE,
  fallback.ok = FALSE,
  snapshot.sources = TRUE,
  implicit.packrat.dependency = TRUE,
  infer.dependencies = TRUE
)

Arguments

project	The project directory. Defaults to current working directory.
available	A database of available packages.
lib.loc	The library to snapshot. Defaults to the private library associated with the given directory.
dry.run	Computes the changes to your packrat state that would be made if a snapshot were performed, and prints them to the console.
ignore.stale	Stale packages are packages that are different from the last snapshot, but were installed by packrat. Typically, packages become stale when a new snapshot is available, but you haven't applied it yet with restore. By default, packrat will prevent you from taking a snapshot when you have stale packages to prevent you from losing changes from the unapplied snapshot. If your intent is to overwrite the last snapshot without applying it, use ignore.stale = TRUE to skip this check.
prompt	TRUE to prompt before performing snapshotting package changes that might be unintended; FALSE to perform these operations without confirmation. Potentially unintended changes include snapshotting packages at an older version than the last snapshot, or missing despite being present in the last snapshot.
auto.snapshot	Internal use – should be set to TRUE when this is an automatic snapshot.
verbose	Print output to the console while snapshot-ing?
fallback.ok	Fall back to the latest CRAN version of a package if the locally installed version is unavailable?
snapshot.sources	Download the tarball associated with a particular package?
implicit.packrat.dependency	Include packrat as an implicit dependency of this project, if not otherwise discovered? This should be FALSE only if you can guarantee that packrat will be available via other means when attempting to load this project.
infer.dependencies	If TRUE, infer package dependencies by examining the R code.
