Atomic and List Type Casting With Names and Dimensions Preserved
Description
Type casting usually strips away attributes of objects.
The functions provided here preserve dimensions, dimnames, and names, which may be more convenient for arrays and array-like objects.
The functions are as follows:
-
as_bool(): converts object to atomic typelogical(TRUE, FALSE, NA). -
as_int(): converts object to atomic typeinteger. -
as_dbl(): converts object to atomic typedouble(AKA numeric). -
as_cplx(): converts object to atomic typecomplex. -
as_chr(): converts object to atomic typecharacter. -
as_raw(): converts object to atomic typeraw. -
as_list(): converts object to recursive typelist.
as_num() is an alias for as_dbl().
as_str() is an alias for as_chr().
See also typeof.
Usage
as_bool(x, ...)
as_int(x, ...)
as_dbl(x, ...)
as_num(x, ...)
as_chr(x, ...)
as_str(x, ...)
as_cplx(x, ...)
as_raw(x, ...)
as_list(x, ...)
Arguments
x
|
an R object. |
…
|
further arguments passed to or from other methods. |
Value
The converted object.
