pub fn emit_function(&mut self, fun: &RFunction)

Emit an R function definition.

pub fn emit_stmt(&mut self, stmt: &RStmt)

Emit a single R statement.

pub fn emit_expr(&mut self, expr: &RExpr) -> String

Emit an R expression to a string (may use output buffer for nested stmts).

pub fn emit_expr_pure(&self, expr: &RExpr) -> String

Emit an R expression to a string (pure, no side-effects on buffer).

pub fn emit_vectorized( &self, op: &VectorizedOp, vec_expr: &RExpr, extra_args: &[RArg], ) -> String
