Error in rendering ggplot (with shiny components) widget i Rmarkdown file

Hello All,
I am trying my hands at making shiny widgets in Rmarkdown documents . I encountered a problem while creating a widget that allows user to choose x and y variables of a data and plots the results. However, generated output chart is incorrect. This generated chart has no axis and the data is represented in incorrect pattern. I am following as a reference.

I usually post with a reprex but while creating one for this it generated the error - Error: callr subprocess failed: Functions that produce HTML output found in document targeting markdown_strict output. Hence requesting you to look at the code below.

title: "Your Document Title"
author: "Document Author"
date: "r Sys.Date()"
theme: cayman
highlight: github
runtime: shiny

knitr::opts_chunk$set(echo = TRUE)


iris ggplot (non interactive)

iris %>% 
  ggplot(aes(Petal.Length, Sepal.Length))+
  geom_jitter(size = 2, alpha = 0.5)

iris interactive ggplot (not functioning well)

selectInput(inputId = "xaxis",label = "X-axis",choices = names(iris)),
selectInput(inputId = "yaxis",label = "Y-axis",choices = names(iris))

  iris %>% 
    ggplot(aes(input$xaxis, input$yaxis))+
    geom_jitter( size = 2, alpha = 0.5)

The pictures of the output are as follows:

1> The usual ggplot output with out the shiny bits

2> The ggplot widget

Hello @garrett,

Sorry for tagging you here out of the blue. I am sure there is some silly thing I am messing up. Requesting to take look at this at your convenience.

Thanking you,

I just figured out what the problem was.

aes_string instead of aes. This is because input$xaxis and input$yaxis are characters.

I am a dummy
