Arguments

phenos	A data.table containing HPO IDs and other metadata.
lvl	How many levels deep into the ontology to get ancestors from. For example: 1: "All" 2: "Phenotypic abnormality" 3: "Abnormality of the nervous system" 4: "Abnormality of nervous system physiology" 5: "Neurodevelopmental abnormality" or "Behavioral abnormality"
hpo	Human Phenotype Ontology object, loaded from get_ontology.
keep_descendants	Terms whose descendants should be kept (including themselves). Set to NULL (default) to skip this filtering step.
remove_descendants	Terms whose descendants should be removed (including themselves). Set to NULL (default) to skip this filtering step.
force_new	Force a new query to the OARD API instead of using pre-downloaded data.
keep_deaths	The age of death associated with each HPO ID to keep. If >1 age of death is associated with the term, only the earliest age is considered. See add_death for details.
all.x	logical; if TRUE, rows from x which have no matching row in y are included. These rows will have 'NA's in the columns that are usually filled with values from y. The default is FALSE so that only rows with data from both x and y are included in the output.
allow.cartesian	See allow.cartesian in [.data.table.
agg_by	Column to aggregate age of onset metadata by.
verbose	Print messages.
evidence_score_threshold	The minimum threshold of mean evidence scores of each gene-phenotype association to keep.
evidence_score_threshold_metric	The metric to use for filtering with evidence_score_threshold.
default_score	Default evidence score to apply to gene-disease associations that are present in the HPO annotations but don't have evidence scores in the GenCC annotations.
...	Arguments passed on to KGExplorer::get_gencc, KGExplorer::map_mondo, KGExplorer::get_ontology_levels save_dir Directory to save a file to. dict A named vector of evidence score mappings. See here for more information. dat data.table with genes. output_col Column name of output IDs. to Character vector of database(s) to map IDs to. When not "mondo", can supply multiple alternative databases to map to (e.g. c("OMIM","Orphanet","DECIPHER")). map_types Mapping types to include. top_n Top number of mappings to return per top_by grouping. Set to NULL to skip this step. add_name Logical, if TRUE, add mondo name column. add_definitions logical, if TRUE, add mondo definition column. ont An ontology of class ontology_DAG. terms A vector of ontology term IDs. remove_terms Character vector of term IDs to exclude. reverse If TRUE, ontology level numbers with be revered such that the level of the parent terms are larger than the child terms.
phenotype_to_genes	Output of load_phenotype_to_genes mapping phenotypes to gene annotations.
gene_frequency_threshold	Only keep genes with frequency above the set threshold. Frequency ranges from 0-100 where 100 is a gene that occurs 100% of the time in a given phenotype. Include NA if you wish to retain genes that do not have any frequency data. See add_gene_frequency for details.
by	A vector of shared column names in x and y to merge on. This defaults to the shared key columns between the two tables. If y has no key columns, this defaults to the key of x.
gene_col	Name of the gene column.
annot	GPT annotation data.
annot_cols	Columns to add.
gpt_filters	A named list of filters to apply to the GPT annotations.
line_length	The number of desired words per line \<int\>
use_api	Get definitions from the HPO API, as opposed to a static local dataset.
ignore_case	Ignore case when mapping terms.
input_col	Name of the column containing the disease or phenotype IDs.
map_to	Mapping outputs to include (from Mondo IDs to another database's IDs).
pheno_ndiseases_threshold	Filter phenotypes by the maximum number of diseases they are associated with.
keep_onsets	The age of onset associated with each HPO ID to keep. If >1 age of onset is associated with the term, only the earliest age is considered. See add_onset for details.
absolute	Make the levels absolute in the sense that they consider the entire ontology (TRUE). Otherwise, levels will be relative to only the terms that are in the provided subset of terms AND are directly adjacent (connected) to a given cluster of terms (FALSE).
keep_ont_levels	Only keep phenotypes at certain absolute ontology levels to keep. See add_ont_lvl for details.
pheno_frequency_threshold	Only keep phenotypes with frequency above the set threshold. Frequency ranges from 0-100 where 100 is a phenotype that occurs 100% of the time in all associated diseases. Include NA if you wish to retain phenotypes that do not have any frequency data. See add_pheno_frequency for details.
drop_na	Whether to drop rows with missing prevalence data.
method	One of "orphanet" or "oard".
severity_threshold	Only keep phenotypes with a mean severity score (averaged across multiple associated diseases) below the set threshold. The severity score ranges from 1-4 where 1 is the MOST severe. Include NA if you wish to retain phenotypes that do not have any severity score.
include_disease_characteristics	Include phenotypes that are also high-level include_disease_characteristics.
auto_assign	Automatically assing HPO IDs to Tiers by conducting regex searches for keywords that appear in the term name, or the names of its descendants or ancestors.
keep_tiers	Tiers from hpo_tiers to keep. Include NA if you wish to retain phenotypes that do not have any Tier assignment.
