Read a target's value from storage.Source:
Read a target's return value from its file in
_targets/objects/. For dynamic files (i.e.
format = "file")
the paths are returned.
Symbol, name of the target to read.
Integer of indices of the branches to load if the target is a pattern.
Data frame of metadata from
tar_read()with the default arguments can be inefficient for large pipelines because all the metadata is stored in a single file. However, if you call
tar_meta()beforehand and supply it to the
metaargument, then successive calls to
tar_read()may run much faster.
Character of length 1, path to the
targetsdata store. Defaults to
tar_config_get("store"), which in turn defaults to
_targets/. When you set this argument, the value of
tar_config_get("store")is temporarily changed for the current function call. See
tar_config_set()for details about how to set the data store path persistently for a project.
The target's return value from its file in
_targets/objects/, or the paths to the custom files and directories
format = "file" was set.
are only for exploratory analysis and literate programming,
tar_load_raw() are only
for exploratory analysis.
loads the correct dependencies into memory when the pipeline
is running, so invoking these functions
from inside a target is rarely advisable.
