Description Usage Arguments Value See Also Examples

View source: R/DBI.R

Description

dimnames returns variable names and row names for the data variables in a design object and dim returns dimensions. For multiple imputation designs there is a third dimension giving the number of imputations. For database-backed designs the second dimension includes variables defined by update. The first dimension excludes observations with zero weight.
