Description

DEPRECATED: use Language.R instead.

Synopsis

Documentation

module Language.R.Instance

class (Applicative m, MonadIO m, MonadCatch m, MonadMask m, PrimMonad m) => MonadR m where Source #

The class of R interaction monads. For safety, in compiled code we normally use the R monad. For convenience, in a GHCi session, we normally use the IO monad directly (by means of a MonadR instance for IO, imported only in GHCi).

Minimal complete definition

getExecContext, unsafeRunWithExecContext

Associated Types

data ExecContext m :: * Source #

A reification of an R execution context, i.e. a "session".

Methods

io :: IO a -> m a Source #

Lift an IO action.

acquire :: s ~ V => SEXP s a -> m (SEXP (Region m) a) Source #

Acquire ownership in the current region of the given object. This means that the liveness of the object is guaranteed so long as the current region remains active (the R garbage collector will not attempt to free it).

acquire :: (MonadIO m, Region m ~ G) => SEXP s a -> m (SEXP (Region m) a) Source #

Acquire ownership in the current region of the given object. This means that the liveness of the object is guaranteed so long as the current region remains active (the R garbage collector will not attempt to free it).

getExecContext :: m (ExecContext m) Source #

Get the current execution context.

unsafeRunWithExecContext :: m a -> ExecContext m -> IO a Source #

Provides no static guarantees that resources do not extrude the scope of their region. Acquired resources are not freed automatically upon exit. For internal use only.
