Evaluation
eval :: MonadR m => SEXP s a -> m (SomeSEXP (Region m)) Source #
Evaluate a (sequence of) expression(s) in the global environment.
eval_ :: MonadR m => SEXP s a -> m () Source #
Silent version of eval function that discards it's result.
evalEnv :: MonadR m => SEXP s a -> SEXP s Env -> m (SomeSEXP (Region m)) Source #
Evaluate a (sequence of) expression(s) in the given environment, returning the value of the last.
Cancel any ongoing R computation in the current process. After interruption
an RError exception will be raised.
This call is safe to run in any thread. If there is no R computation running, the next computaion will be immediately cancelled. Note that R will only interrupt computations at so-called "safe points" (in particular, not in the middle of a C call).
Exceptions
Throw an R error as an exception.
throwRMessage :: MonadR m => String -> m a Source #
Throw an R exception with specified message.
Deprecated
parseFile :: FilePath -> (SEXP s Expr -> IO a) -> IO a Source #
Deprecated: Use [r| parse(file="pathtofile") |] instead.
Parse file and perform some actions on parsed file.
This function uses continuation because this is an easy way to make operations GC-safe.
Arguments
| :: String | Text to parse |
| -> Bool | Whether to annotate the AST with source locations. |
| -> IO (SEXP V Expr) |
Deprecated: Use [r| parse(text=...) |] instead.
