Error: attempt to apply non-function

[schlichtanders]

For some julia values, the call method is not supported on R side

PlutoUI = julia_eval("using PlutoUI; PlutoUI")
PlutoUI$Slider(c(1,2,3))

returns

REvalError: Error: attempt to apply non-function

    var"#handle_eval_stderr#31"(::Bool, ::typeof(RCall.handle_eval_stderr))@io.jl:174

It would be great if the R call syntax works also here to run the julia call.

This is most frequent problem I have with JuliaCall

Workaround

julia_call("PlutoUI.Slider", c(1,2,3))

Another example:

HTML <- julia_eval("HTML")
HTML("<h1> title </h1>")

gives an error

could not find function "HTML"

despite it is callable on julia side
