Initial graph output error #10
Description
After gMCPShiny::run_app(), the initial graph out can not be generated and an error returns:
Error: error in evaluating the argument 'x' in selecting a method for function 'print': <ggplot2::element_text> object properties are invalid:
- @hjust must be <NULL>, <integer>, or <double>, not <character>
I think it's from hjust used in graph-output.R and server side input$title.position and input$caption.position are character values based on selectInput() documentation.
