reshape_ci: Reshape CI between wide/long formats

In datawizard: Easy Data Wrangling and Statistical Transformations

Reshape CI between wide/long formats

Description

Reshape CI between wide/long formats.

Usage

reshape_ci(x, ci_type = "CI")

Arguments

x

A data frame containing columns named CI_low and CI_high (or similar, see ci_type).

ci_type

String indicating the "type" (i.e. prefix) of the interval columns. Per easystats convention, confidence or credible intervals are named CI_low and CI_high, and the related ci_type would be "CI". If column names for other intervals differ, ci_type can be used to indicate the name, e.g. ci_type = "SI" can be used for support intervals, where the column names in the data frame would be SI_low and SI_high.

Value

A data frame with columns corresponding to confidence intervals reshaped either to wide or long format.

Examples

x <- data.frame(
  Parameter = c("Term 1", "Term 2", "Term 1", "Term 2"),
  CI = c(0.8, 0.8, 0.9, 0.9),
  CI_low = c(0.2, 0.3, 0.1, 0.15),
  CI_high = c(0.5, 0.6, 0.8, 0.85),
  stringsAsFactors = FALSE
)

reshape_ci(x)
reshape_ci(reshape_ci(x))
