Implementations§

Source§

impl SEXPTYPE

Source

pub const OBJSXP: SEXPTYPE = SEXPTYPE::S4SXP

Alias for S4SXP (value 25).

R defines both OBJSXP and S4SXP as value 25. S4SXP is retained for backwards compatibility; OBJSXP is the preferred name.

Source

pub fn type_name(self) -> &'static str

Get R’s name for this SEXPTYPE (e.g. "double", "integer", "list").

Returns the same string as R’s typeof() function.
