R: "Knit to Flexdashboard" Button Doesn't Always Appear?-CodePudding

I am working with the R programming language.

I have noticed that when I am working with R markdown, the "Knit to Flexdashboard" button doesn't always appear. For example - over here, it appears:

And over here, it does not:

When I open R Studio, I always make to first load the "flexdashboard" library:

library(flexdashboard)

Then, I click "File" -> "New File" -> "R Markdown"

And I create a new document and click "create".

Yet, sometimes I notice that the "Knit to Flexdashboard" button is there, and sometimes the "Knit to Flexdashboard" button is not there.

Does anyone know why this is happening and what I can do fix this problem?

Thanks!

As I have said in comments above - you can choose output formats for your rmarkdown doc manually.

In your case is:

---
title: "Untitled"
output: 
  flexdashboard::flex_dashboard
---

Also exists a lot of others formats, look here: https://rmarkdown.rstudio.com/lesson-9.html and there: https://bookdown.org/yihui/rmarkdown/output-formats.html

They forget to add xarigan and I don't see the posterdown.

So, you have chosen the required format - push the Knit with parameters and voilà.

The more lazy variant "File" -> "New File" -> "R Markdown" -> "From Template" hasn't all output formats and sometimes you will be forced to choose it manually (or you can prepare your own templates respectively).

Good luck.
