In slideimp: Numeric Matrices K-NN and PCA Imputation

Resolve a Group Specification to a Data Frame

Description

Convert a group specification to the canonical data-frame form expected by prep_groups(). This S3 generic is exported so that extension packages, such as slideimp.extra, can register additional methods.

Usage

slideimp_resolve_group(x)

## S3 method for class 'data.frame'
slideimp_resolve_group(x)

## Default S3 method:
slideimp_resolve_group(x)

Arguments

x	A group specification. slideimp provides a method for data.frame objects. The optional slideimp.extra package provides a method for character platform names.

Value

A data frame group specification, or an error for unsupported inputs.

Note

This is primarily an extension hook for slideimp.extra.

Examples

df <- data.frame(feature = c("cg1", "cg2"), group = c(1, 1))
slideimp_resolve_group(df)
