Interactions from the EVEX database

Downloads interactions from EVEX, a versatile text mining resource (http://evexdb.org). Translates the Entrez Gene IDs to Gene Symbols and combines the interactions and references into a single data frame.

Usage

evex_download(
    min_confidence = NULL,
    remove_negatives = TRUE,
    top_confidence = NULL
)

Arguments

min_confidence

Numeric: a threshold for confidence scores. EVEX confidence scores span roughly from -3 to 3. By providing a numeric value in this range the lower confidence interactions can be removed. If NULL no filtering performed.

remove_negatives

Logical: remove the records with the "negation" attribute set.

top_confidence

Confidence cutoff as quantile (a number between 0 and 1). If NULL no filtering performed.

Value

Data frame (tibble) with interactions.
