## Class-dependent variable aggregation

### Description

Summarize a vector/variable into a single number, either a mean (median) for numeric vectors or the mode for categorical (character, factor, ordered, or logical) vectors. Useful for aggregation.

### Usage

    mean_or_mode(x)

    ## Default S3 method:
    mean_or_mode(x)

    ## S3 method for class 'numeric'
    mean_or_mode(x)

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

    median_or_mode(x)

    ## Default S3 method:
    median_or_mode(x)

    ## S3 method for class 'numeric'
