is_labelled

is.labelled

Functions to determine if a vector has a label.

Labels are a common construct in statistical software providing a
human readable description of a variable. While variable names are succinct,
quick to type, and follow a language's naming conventions, labels may
be more illustrative and may use plain text and spaces. R does not provide
native support for labels. Some packages, however, have made this feature
available.  Most notably, the 'Hmisc' package provides labelling methods
for a number of different object. Due to design decisions, these methods
are not all exported, and so are unavailable for use in package development.
The 'labelVector' package supports labels for atomic vectors in a light-weight
design that is suitable for use in other packages.
