detect_scales: Detect item scales

Description

Did you create aggregates of items like this scale <- scale_1 + scale_2R + scale_3R? If you run this function on a dataset, it will detect these relationships and set the appropriate attributes. Once they are set, the codebook package can perform reliability computations for you.

Usage

detect_scales(data, quiet = FALSE)
detect_scales(data, quiet = FALSE)

Arguments

data

the data frame

quiet

defaults to false. Suppresses messages about found items.

Examples

bfi <- data.frame(matrix(data = rnorm(300), ncol = 3))
names(bfi) <- c("bfi_e1", "bfi_e2R", "bfi_e3")
bfi$bfi_e <- rowMeans(bfi[, c("bfi_e1", "bfi_e2R", "bfi_e3")])
bfi <- detect_scales(bfi)
bfi$bfi_e
bfi <- data.frame(matrix(data = rnorm(300), ncol = 3))
names(bfi) <- c("bfi_e1", "bfi_e2R", "bfi_e3")
bfi$bfi_e <- rowMeans(bfi[, c("bfi_e1", "bfi_e2R", "bfi_e3")])
bfi <- detect_scales(bfi)
bfi$bfi_e
