This function Calls STRING's API to Convert a set of identifiers to STRING Identifiers. Although You can call STRING services with a variety of common identifiers, It is recommended by STRING's documentations that you first map Your Protein/genes IDs to STRING IDs and then proceed with other STRING's functions.

rba_string_map_ids(ids, species = NULL, echo_query = FALSE, limit = NULL, ...)



Your Common gene/protein Identifier(s) to be mapped.


Numeric: NCBI Taxonomy identifier; Human Taxonomy ID is 9606. (Recommended, but optional if your input is less than 100 IDs.)


(default = FALSE) Include your input IDs as a column of the results.


(Numeric, Optional) A limit on the number of matches per input ID.


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


A data frame with the mapped STRING IDs and other pertinent information.
