Description
Coercion of spam
matrices to proper vector objects
Usage
## S4 method for signature 'spam'
as.vector(x, mode = "any")
Arguments
x |
spam object. |
mode |
character string naming an atomic mode or |
Details
This coercion allows smooth transitions between different
matrix formats, see example below.
The Cholesky factors are first transformed to a spam
object.
Value
If structurebased=TRUE
, the vector x@entries
.
Conversely, if structurebased=FALSE
, the result is identical to
one with as.vector(as.matrix(x))
.
