generates an environment similar to as.environment(ds1)
, but makes
variables available by their VAR_NAME
, LABEL
, and label_col
- names.
util_ds1_eval_env(study_data, meta_data = "item_level", label_col = LABEL)
data.frame the data frame that contains the measurements
data.frame the data frame that contains metadata attributes of study data
variable attribute the name of the column in the metadata
with labels of variables. If
study_data
has already been mapped,
i.e., util_ds1_eval_env(ds1, ...)
is
called, this will work too
