Assign an Integer Value to a Julia Variable

This function wraps `JuliaCall::julia_assign` to assign a value from R to a Julia variable, and then explicitly casts the variable to the `Integer` type in Julia.

Usage

julia_assign_int(x, value)

Arguments

x

A character string. The name of the Julia variable to assign the value to.

value

The R object to assign to the Julia variable. This will be passed to Julia.

Value

Invisibly returns `NULL`. The main effect is side-effects in the Julia session.

Details

The function first assigns the value from R to a variable named `x` in the Julia session using `JuliaCall::julia_assign`. It then forces Julia to cast the variable to the `Integer` type using Julia's `Integer()` constructor.

Note: This function assumes that the `value` provided is compatible with Julia's `Integer` type. If it is not, an error will be thrown by Julia.

Examples

if (FALSE) { # \dontrun{
julia_assign_int("x", 3.5)  # Will be cast to 3L in Julia
JuliaCall::julia_eval("x")  # Returns 3 (as Integer in Julia)
} # }
