riskmetric (version 0.2.5)

pkg_score: Score a package assessment, collapsing results into a single numeric

Description

pkg_score() calculates the risk involved with using a package. Risk ranges from 0 (low-risk) to 1 (high-risk).

Usage

pkg_score(x, ..., error_handler = score_error_default)

Value

A numeric value if a single pkg_metric is provided, or a

tibble with pkg_metric objects scored and returned as numeric values when a tibble is provided.

Arguments

x

A pkg_metric object, whose subclass is used to choose the appropriate scoring method for the atomic metric metadata. Optionally, a tibble can be provided, in which cases all pkg_metric values will be scored.

...

Additional arguments passed to summarize_scores when an object of class tbl_df is provided, unused otherwise.

error_handler

Specify a function to be called if the class can't be identified. Most commonly this occurs for pkg_metric objects of subclass pkg_metric_error, which is produced when an error is encountered when calculating an associated assessment.
