I have this Error when I first time using R Markdown, just a simple test run.
---
title: "test"
author: "Lulu"
date: "3/6/2018"
output: html_document
---
```{r}
library(datasets)
data("airquality")
summary(airquality)
```
then it reports:
output file: test.knit.md
Error: 'is_latex_output' is not an exported object from 'namespace:knitr'
Execution halted
Does anyone know how to solve it?
Not the most current version
You can try update Knitr
install.packages('knitr', repos = c('http://rforge.net', 'http://cran.rstudio.org'),
type = 'source')
