Examples

# library(jack)
if(JuliaConnectoR::juliaSetupOk()){
  julia <- Jack_julia()
  ( pol <- julia$JackPol(m = 2, lambda = c(3, 1), alpha = "3/2") )
  f <- as.function(pol)
  f(2, "3/7")
  # the evaluation is performed by (R)yacas and complex numbers are
  # allowed; the imaginary unit is denoted by `I`
  f("2 + 2*I", "1/4")
