get_factor_atts: Get Factor Attributes from a Labeled Data Frame

Description

get_factor_atts searches a labelr labeled data.frame for factors. If any are found, a list of character vectors of factor levels is returned, with each character vector being the set of unique levels for a factor variable, and with each character vector named according to the convention "factor." + variable name (e.g.,"factor.Species" for iris$Species). Used internally by other labelr functions to get information about factors in labeled data.frames.

Usage

get_factor_atts(data)

Value

A list of character vectors, each named according to the convention "factor." + variable name (e.g.,"factor.Species" for iris$Species). If the data.frame lacks labelr attributes or lacks factors, an empty list will be returned.

Arguments

data

the labelr labeled data.frame you are checking for factor variables.

Examples

ir2 <- iris
unique(ir2$Species)

ir2 <- add_val_labs(ir2,
  vars = "Species", vals = c(
    "setosa",
    "versicolor",
    "virginica"
  ),
  labs = c("se", "ve", "vi")
)
get_val_labs(ir2)
head(use_val_labs(ir2))
get_factor_atts(iris) # no such info: iris is not labelr labeled
get_factor_atts(ir2) # this one has info: it's labelr labeled
