Imports interactions from the `ligrec extra` dataset of OmniPathSource:
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.
import_ligrecextra_interactions( resources = NULL, organism = 9606, fields = NULL, default_fields = TRUE, references_by_resource = TRUE, exclude = NULL, strict_evidences = FALSE, ... )
interactions not reported in these databases are removed. See
get_interaction_resourcesfor more information.
Interactions are available for human, mouse and rat. Choose among: 9606 human (default), 10116 rat and 10090 Mouse
The user can define here the fields to be added. If used, set the next argument, `default_fields`, to FALSE.
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.
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.
Character: datasets or resources to exclude.
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
A dataframe containing ligand-receptor interactions including the ones without literature references
interactions <- import_ligrecextra_interactions( resources = c('HPRD', 'Guide2Pharma'), organism = 9606 )
