implicit_guide.data.frame | R Documentation |
Coerces data.frame guide-like attributes to 'guide'.
The attribute 'guide' generally suggests a guide
to interpretation of a data item, such as units, formats, codelists,
and encodings. The idea here is to replace these with 'guide':
i.e., to undo the effects of explicit_guide.data.frame
.
If guide attribute is still present, the explicit attribute is removed.
Otherwise the explicit element is renamed.
## S3 method for class 'data.frame'
implicit_guide(x, ..., collapse = getOption("yamlet_collapse_codelist", 10))
x |
data.frame |
... |
named arguments ignored; un-named arguments limit scope |
collapse |
numeric: substitute empty codelist if number of levels exceeds this. Set to Inf to ensure levels are always stored explicitly; if zero, empty codelist will always be substituted if codelist elements are un-named and exactly match |
