addTagsRepo {archivist}R Documentation

Add new Tags to the Existing Repository


addTagsRepo adds new Tags to the existing Repository.


addTagsRepo(md5hashes, repoDir = NULL, FUN = NULL, tags = NULL, ...)



a character vector of md5hashes specifying to which corresponding artifacts new Tags should be added. See Note to get to know about the length of tags and md5hashes parameters.


A character that specifies the directory of the Repository to which new Tags will be added. If it is set to NULL (by default), it uses the repoDir specified in setLocalRepo.


A function which is evaluated on the artifacts for which md5hashes are given. The result of this function evaluation are Tags which will be added to the local Repository.


A character vector which specifies what kind of Tags should be added to artifacts corresponding to given md5hashes. See Note to get to know about the length of tags and md5hashes parameters. One can specify either FUN or tags.


Other arguments that will be passed to FUN.


addTagsRepo function adds new Tags to artifacts that are already stored in the repository. One can add new Tags either explicitly with tags parameter or by passing a function which extracts Tags from selected artifacts corresponding to md5hashes. To learn more about artifacts visit archivist-package.


Bug reports and feature requests can be sent to


One should remember that length(tags) modulo length(md5hashes) must be equal to 0 or length(md5hashes) modulo length(tags) must be equal to 0.
