Grouped comparison summary

Description

Grouped comparison summary

Usage

imed_compare(x, group, value = "Mean")

Arguments

`x`	An 'imed_db', or a measurement-level data frame such as the output of 'imed_analysis_set()'. The comparability guard is applied, so the records must belong to one compatible comparability class.
`group`	Grouping field (unquoted or quoted name).
`value`	Name of the numeric measurement field to summarise (default '"Mean"').

Value

A 'tibble' of descriptive statistics with one row per group, as returned by 'imed_describe()' with a 'group' argument.

Examples

toy <- data.frame(
  Study_ID = paste0("S", 1:12),
  Comparability_Class = "CLASS_A",
  Reported_Unit = "items/L",
  Metric_Type = "Abundance",
  Strict_Synthesis_Eligibility = "YES",
  Group = rep(c("g1", "g2"), 6),
  Mean = c(2.1, 3.4, 1.8, 4.0, 2.9, 3.1, 2.4, 3.8, 1.9, 3.3, 2.7, 4.2),
  SD = rep(c(0.6, 0.9), 6),
  N = rep(c(10, 12, 8), 4)
)
imed_compare(toy, group = "Group")
