Passing array of lenght 1 to .NET

[PavelBal]

Currently not supported as R always converts an array of length 1 to a scalar.

test_that("Basic types of length one are passed correctly from R to .NET", {
  expectArrayElementType(numeric(1), "System.Double")
  expectArrayElementType(integer(1), "System.Int32")
  expectArrayElementType(raw(1), "System.Byte")
  expectArrayElementType(logical(1), "System.Boolean")
  expectArrayElementType(character(1), "System.String")
  expectArrayElementType("a", "System.String")
})

Error in do.call(".External", c(list("r_call_static_method", typename,  : 
  Type:    System.MissingMethodException
Message: Could not find a suitable static method CheckElementType on type ClrFacade.TestArrayMemoryHandling for method parameters Double, RuntimeType
