Imports interactions from the `omnipath` dataset of Omnipath

Source: R/interactions.R
import_omnipath_interactions.Rd

Imports the database from https://omnipathdb.org/interactions, which contains only interactions supported by literature references. This part of the interaction database compiled a similar way as it has been presented in the first paper describing OmniPath (Turei et al. 2016).

Usage

import_omnipath_interactions(
  resources = NULL,
  organism = 9606,
  datasets = "omnipath",
  fields = NULL,
  default_fields = TRUE,
  references_by_resource = TRUE,
  exclude = NULL,
  strict_evidences = FALSE,
  ...
)

Arguments

resources

interactions not reported in these databases are removed. See get_interaction_resources for more information.

organism

Interactions are available for human, mouse and rat. Choose among: 9606 human (default), 10116 rat and 10090 Mouse

datasets

Names of the interaction datasets to download: omnipath (by default). Other possiblites are: pathwayextra, kinaseextra, ligrecextra, dorothea,tf_target, mirnatarget, tf_mirna, lncrna_mrna. The user can select multiple datasets as for example: c('omnipath', 'pathwayextra', 'kinaseextra')

fields

The user can define here the fields to be added. If used, set the next argument, `default_fields`, to FALSE.

default_fields

whether to include the default fields (columns) for the query type. If FALSE, only the fields defined by the user in the `fields` argument will be added.

references_by_resource

if FALSE, removes the resource name prefixes from the references (PubMed IDs); this way the information which reference comes from which resource will be lost and the PubMed IDs will be unique.

exclude

Character: datasets or resources to exclude.

strict_evidences

Logical: restrict the evidences to the queried datasets and resources. If set to FALSE, the directions and effect signs and references might be based on other datasets and resources.

...

optional additional arguments

Value

A dataframe of protein-protein interactions
