R markdown gets stuck on chunk 1, which is repeated below:
---
title: "RMark1"
author: "df"
date: "11/19/2017"
output:
html_document:
toc: true
---
```{r setup}
library(dplyr)
library(knitr)
library(rmarkdown)
library(ggplot2)
library(plotly)
library(readr)
knitr::opts_chunk$set(echo = TRUE)
print("loaded libraries")
```
what am I missing here?
