devalued.observations: Aggregate Values for Observations Aggregates values for...

In tablet: Tabulate Descriptive Statistics in Multiple Formats

Aggregate Values for Observations Aggregates values for observations. Accepts a list of formulas with result name on left and aggregating expression on the right. Behavior is undefined if any expression does not aggregate! (I.e., length != 1). Expressions are evaluated in an environment where values are available as 'x', grouped count is available as 'n' and ungouped count is available as 'N'.

Description

Aggregate Values for Observations Aggregates values for observations. Accepts a list of formulas with result name on left and aggregating expression on the right. Behavior is undefined if any expression does not aggregate! (I.e., length != 1). Expressions are evaluated in an environment where values are available as 'x', grouped count is available as 'n' and ungouped count is available as 'N'.

Usage

## S3 method for class 'observations'
devalued(
  x,
  ...,
  fun = list(sum ~ sum(x, na.rm = TRUE), pct ~ signif(digits = 3, sum/n * 100), ave ~
    signif(digits = 3, mean(x, na.rm = TRUE)), std ~ signif(digits = 3, sd(x, na.rm =
    TRUE)), med ~ signif(digits = 3, median(x, na.rm = TRUE)), min ~ signif(digits = 3,
    min(x, na.rm = TRUE)), max ~ signif(digits = 3, max(x, na.rm = TRUE))),
  silent = TRUE
)

Arguments

x	observations
...	passed formulas with matching LHS will replace corresponding element of fun.
fun	default aggregate functions expressed as formulas
silent	whether to suppress warnings from evaluations of 'fun'

Value

class 'devalued', presumably one record per group:

_tablet_N	number of records
_tablet_n	number of records in group
_tablet_name	observation identifier
_tablet_level	factor level (or special value 'numeric' for numerics)
(other)	additional column for each statistic in 'fun'
