1 | aggregate_and_document_scale(items, fun = rowMeans, stem = NULL)
|
items |
data.frame of the items that should be aggregated |
fun |
aggregation function, defaults to rowMeans with na.rm = FALSE |
stem |
common stem for the variables, specify if it should not be auto-detected as the longest common stem of the variable names |
1 2 3 4 5 | testdf <- data.frame(bfi_neuro_1 = rnorm(20), bfi_neuro_2 = rnorm(20),
bfi_neuro_3R = rnorm(20), age = rpois(20, 30))
item_names <- c('bfi_neuro_1', 'bfi_neuro_2', 'bfi_neuro_3R')
testdf$bfi_neuro <- aggregate_and_document_scale(testdf[, item_names])
testdf$bfi_neuro
