Realize a DelayedArray object
Realize a DelayedArray object in memory or on disk.
realize(x, ...) ## S4 method for signature 'ANY' realize(x, BACKEND=getAutoRealizationBackend())
x |
The array-like object to realize. |
... |
Additional arguments passed to methods. |
BACKEND |
A single string specifying the name of the realization backend.
Use the current automatic realization backend by default i.e.
the backend returned by |
A DelayedArray object. More precisely, it returns
DelayedArray(as.array(x)) when the backend is set to
NULL (the default). Otherwise it returns an instance of the
class associated with the specified backend (which should extend
DelayedArray).
