+ Sets or retrieves the %\code{"label"},%
+ \code{"SASformat"},
+ \code{"SASiformat"}, or \code{SAStype} attribute of an object.
+
+ More comprehensive support for object labels, and SASformat, are
+ available in Frank Harrell's \code{Hmisc} package.
+
+ Note that \code{SAStype} enforces the SAS 8-character naming convention.
