Converts a tibble into a plain data frame with no column attributes.
Examples
# Path where raw 'SPSS' files are
input <- system.file("extdata/reds", package = "ILSAmerge")
# Load complete data
fulllist <- justload(inputdir = input, population = "BCGV1", justattributes = FALSE)
# Untibble first element
unt1 <- untibble(fulllist[[1]])
# Untibble all list
unt2 <- untibble(fulllist)
