I am having issues running Rmarkdown and Project, and its associated output.
`
---
title: "Untitled"
author: "Oluwadare, Margaret"
date: "August 5, 2020"
output: html_document

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## R Markdown
This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.
When you click the **Knit** button a document will be generated that includes both contents as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
```{r cars}
summary(cars)
```
## Including Plots
You can also embed plots, for example:
```{r pressure, echo=FALSE}
plot(pressure)
```
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
`
it gives me the following warning messages.

Also when I tried to use reprex() to report the above issues I got an error message as follows:
reprex()
``

This challenge has been on since I updated R, Rstudio, and all the packages. I had to do package update to be sure the packages on my Rstudio are not outdated. But still, the challenge persists. Below are my session information and version details:
