RS types for validation of RS class attributes.

Source: R/types.R
RSTypes.Rd

Supported types for RS classes include:

  • t_any

  • t_date, t_dates

  • t_int, t_ints

  • t_dbl, t_dbls

  • t_num, t_nums

  • t_char, t_chars

  • t_bool, t_bools

  • t_cplx, t_cplxs

  • t_raw, t_raws

  • t_factor, t_factors

  • t_list

  • t_array

  • t_vector

  • t_matrix

  • t_dataframe

  • t_hashtab

  • t_environment

  • t_pairlist

  • t_func

  • t_expr

  • t_call

  • t_sym

  • t_lang

  • t_obj

  • t_prim

Note that there are scalar and vector versions of some types, such as t_int and t_ints. The former allows for a single scalar integer, while the latter matches a vector of integers.

There is also the catch-all type t_any, which will match any value, and is useful for cases where you want to allow any type of value for a field, while still validating the other fields, i.e. when .validation = TRUE (the default).
