juliaExpr: Mark a string as Julia expression

In JuliaConnectoR: A Functionally Oriented Interface for Integrating 'Julia' with R

Mark a string as Julia expression

Description

A given R character vector is marked as a Julia expression. It will be executed and evaluated when passed to Julia. This allows to pass a Julia object that is defined by complex Julia syntax as an argument without needing the round-trip to R via juliaEval or juliaLet.

Usage

juliaExpr(expr)

Arguments

expr	a character vector which should contain one string

Examples

if (juliaSetupOk()) {

   # Create complicated objects like version strings in Julia, and compare them
   v1 <- juliaExpr('v"1.0.1"')
   v2 <- juliaExpr('v"1.2.0"')
   juliaCall("<", v1, v2)

}
