Get Protein-Protein Interaction Enrichment

Source: R/stringdb.R
rba_string_enrichment_ppi.Rd

Even when there is no annotation for your input proteins, STRING can Compare your Given proteins interactions pattern with the background proteome-wide interaction distribution to determine if your given set of proteins are functionally related.

Usage

rba_string_enrichment_ppi(
  ids,
  species = NULL,
  required_score = NULL,
  background = NULL,
  ...
)

Arguments

ids

Your protein ID(s). It is strongly recommended to supply STRING IDs. See rba_string_map_ids for more information.

species

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

required_score

Numeric: A minimum of interaction score for an interaction to be included in the image. if not supplied, the threshold will be applied by STRING Based in the network. (low Confidence = 150, Medium Confidence = 400, High Confidence = 700, Highest confidence = 900)

background

character vector: A set of STRING protein IDs to be used as the background proteome. Only STRING IDs are acceptable. (See rba_string_map_ids to map your IDs.)

...

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

Value

A list with protein-protein interaction enrichment results.
