Load Artifact Given as a md5hash from a Repository
loadFromLocalRepo loads an artifact from a local Repository into the workspace.
loadFromRemoteRepo loads an artifact from a github / git / mercurial Repository into the workspace.
To learn more about artifacts visit archivist-package.
loadFromLocalRepo(md5hash, repoDir = aoptions("repoDir"), value = FALSE) loadFromRemoteRepo(md5hash, repo = aoptions("repo"), user = aoptions("user"), branch = aoptions("branch"), subdir = aoptions("subdir"), repoType = aoptions("repoType"), value = FALSE)
Arguments
| md5hash | A character assigned to the artifact through the use of a cryptographical hash function with MD5 algorithm, or it's abbreviation. |
|---|---|
| repoDir | A character denoting an existing directory from which an artifact will be loaded. |
| value | If |
| repo | While working with a Remote repository. A character containing a name of a Remote repository on which the Repository is archived.
By default set to |
| user | While working with a Remote repository. A character containing a name of a Remote user on whose account the |
| branch | While working with a Remote repository. A character containing a name of
Remote Repository's branch on which the Repository is archived. Default |
| subdir | While working with a Remote repository. A character containing a name of a directory on Remote repository
on which the Repository is stored. If the Repository is stored in main folder on Remote repository, this should be set
to |
| repoType | A character containing a type of the remote repository. Currently it can be 'Remote' or 'bitbucket'. |
Details
Functions loadFromLocalRepo and loadFromRemoteRepo load artifacts from the archivist Repositories
stored in a local folder or on git. Both of them take md5hash as a
parameter, which is a result of saveToRepo function.
For each artifact, md5hash is a unique string of length 32 that is produced by
digest function, which uses a cryptographical MD5 hash algorithm. For more information see md5hash.
Important: instead of giving the whole md5hash character, the user can simply give first few characters of the md5hash.
For example, a09dd instead of a09ddjdkf9kj33dcjdnfjgos9jd9jkcv. All artifacts with the same md5hash
abbreviation will be loaded from Repository.
Note that user and repo should be used only when working with a git repository and should be omitted in the local mode.
repoDir should only be used when working on a local Repository and should be omitted in the git mode.
One may notice that loadFromRemoteRepo and loadFromLocalRepo load artifacts to the Global
Environment with their original names. Alternatively,
a parameter value = TRUE can be specified so that these functions may return artifacts as a value. As a result loaded artifacts
can be attributed to new names. Note that, when an abbreviation of md5hash was given then a list of artifacts corresponding to this
abbreviation will be loaded.
Note
You can specify one md5hash (or its abbreviation) per function call.
If repo and user are set to NULL (as default) in Remote mode then global parameters
set in setRemoteRepo function are used.
You should remember while using loadFromRepo wrapper that repoDir is
a parameter used only in loadFromLocalRepo while repo, user,
branch and subdir are used only in loadFromRemoteRepo. When you mix those
parameters you will receive an error message.
