Vector to array conversion

Description

Convert a vector into an array given a set of dimensions; it therefore simply wraps aperm() and array().

Usage

vec2tab(vec, dim)

Arguments

vec	A vector
dim	The desired array dimensions, oftentimes a vector of the number of levels of each variable in order

Details

This function converts an array (or a multi-way contingency table) into a vector, using a consistent ordering of the cells. The ordering of the cells is lexicographic and cannot be specified by the user.

Value

An array

See Also

tab2vec(), aperm(), array()

Examples

data(Titanic)
str( Titanic )
str( tab2vec(Titanic) )

# convert it back into a table (names are removed)
vec2tab(
  tab2vec(Titanic), 
  dim(Titanic)
)

# check that they are the same
all( vec2tab(tab2vec(Titanic), dim(Titanic)) == Titanic )
