I have some trouble in using Shiny in Rmarkdown.
It seems my Shiny does not generate variale input at all.
Here is the code:
numericInput("rows", "How many cars?", 5) renderTable({ head(cars, input$rows) })

You might want to investigate updating your shiny and rmarkdown pacakages.
shiny
rmarkdown
I tired and installed those packages again and again. Same error...
The issue is with the newest version of the rmarkdown package:
If you install the development version, the problem should go away:
if (!require("devtools")) install.packages("devtools") devtools::install_github("rstudio/rmarkdown")
If you don't want to go that route, it looks like they expect to release the patch to CRAN fairly soon.
Thanks. Installing former package of rmarkdown solved the problem.
