You can use this function to list the JASPAR TF flexible models (TFFMs) that match your search query, or run the function without any arguments to return a list of every matrix profile available in the latest release.

  term = NULL,
  release = 2020,
  tax_group = NULL,
  search = NULL,
  order = NULL,
  page_size = 1000,
  page = 1,



Character: A search term.


Numeric: (default = 2020) Which JASPAR database release to use? Available options are: 2014, 2016, 2018, and 2020.


Character: Taxonomic group. Use rba_jaspar_taxons to get a list of supported Taxonomic groups.


Character: A search term.


Character: A character string or a vector of character strings of field names that will be used to order the results.

Numeric: Which page of the results to retrieve? The accepted values depend on the page size and number of results.


rbioapi option(s). See rba_options's arguments manual for more information on available options.


A list that contains a data frame with information of query hits' TFFMs.


Note that this is a search function. Thus, you are not required to fill every argument; You may use whatever combinations of arguments you see fit for your query.
