This helper function names any unnamed elements in the blocks
specification. This is a convenience function.
Usage
name.blocks(blocks, prefix = "B")
Value
A named list of character vectors with variables names.
Arguments
blocks
List of vectors with variable names per block. List elements
may be named to identify blocks. Variables within a block are
imputed by a multivariate imputation method
(see method argument). By default each variable is placed
into its own block, which is effectively
fully conditional specification (FCS) by univariate models
(variable-by-variable imputation). Only variables whose names appear in
blocks are imputed. The relevant columns in the where
matrix are set to FALSE of variables that are not block members.
A variable may appear in multiple blocks. In that case, it is
effectively re-imputed each time that it is visited.
prefix
A character vector of length 1 with the prefix to
be using for naming any unnamed blocks with two or more variables.
Details
This function will name any unnamed list elements specified in
the optional argument blocks. Unnamed blocks
consisting of just one variable will be named after this variable.
Unnamed blocks containing more than one variables will be named
by the prefix argument, padded by an integer sequence
stating at 1.
