Fiddle Selection breaks if first number negative

[BobOtike]

When I try to create a vector from space-delimited values I get this error when using Fiddle Selection:

Error in rstudioapi::modifyRange(doc_context$range, text = vector_form) : 
  object 'vector_form' not found

Simple example is to type -1 2 into the console, mark it and execute Fiddle Selection. When I remove the leading - it works.

Thanks for the example :)
