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)
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.
