I've installed wxPython package and issued loaded wxPython library and called  
aforementioned function, here is an output that R gave me:

> library(wxPython)
Creating a new generic function for "print" in "wxPython"
Loading required package: RSPython
Initialized R-Python interface package.

Examples are available by typing: wxPythonUserManual()

Warning message:
the Python callback manager has been registered implicitly using the defaults  
(referenceManager())!
> getMethod("wxShow","wxDialog")
Method Definition (Class "MethodDefinition"):

function (frm, ...)
{
    .local <- function (frm, envir = parent.frame(n = 2))
    {
        frm <- wxDialogPython(frm, modal = FALSE)
        wxRegisterWindow(frm, envir = envir)
        return(frm)
    }
    .local(frm, ...)
}
<environment: 0x90a1d64>

Signatures:
        frm
target  "wxDialog"
defined "wxDialog"

No errors. Or there shouldn't be any?

How do you use "import parser"? What should I type into R to issue such kind  
of command?
