Atomic Type Casting Without Stripping Attributes
Description
Atomic type casting in R is generally performed using the functions
as.logical, as.integer,
as.double, as.character,
as.complex, and as.raw.
Converting an object between atomic types using these functions
strips the object of its attributes,
including attributes such as names and dimensions.
The functions provided here by the 'tinycodet' package
preserve all attributes - except the "class" attribute.
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 decimal numbers). -
as_chr()
: converts object to atomic typecharacter
. -
as_cplx()
: converts object to atomic typecomplex
. -
as_raw()
:converts object to atomic typeraw
.
Usage
as_bool(x, ...)
as_int(x, ...)
as_dbl(x, ...)
as_chr(x, ...)
as_cplx(x, ...)
as_raw(x, ...)
Arguments
x |
vector, matrix, array (or a similar object where all elements share the same type). |
... |
further arguments passed to or from other methods. |
Value
The converted object.

Examples
x <- c(rep(0, 2), seq(0, 2.5, by=0.5)) |> matrix(ncol=2)
colnames(x) <- c("one", "two")
attr(x, "test") <- "test"
print(x)
# notice that in all following, attributes (except class) are conserved:
as_bool(x)
as_int(x)
as_dbl(x)
as_chr(x)
