Imports the dataset from: https://omnipathdb.org/interactions?datasets=ligrecextra, which contains ligand-receptor interactions without literature reference. The ligand-receptor interactions supported by literature references are part of the omnipath dataset.

## Usage

import_ligrecextra_interactions(
resources = NULL,
organism = 9606,
fields = NULL,
default_fields = TRUE,
references_by_resource = TRUE,
exclude = NULL,
...
)

## 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

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.
