I have knitted an html document in R. The output is good; it's just that at the very end I see this note:
Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot
How can I remove this note from showing in the knitted document?
This doesn't appear in my version of Rmarkdown running the test document below:
---
title: R Markdown
output: html_document
---
This is an R Markdown document.
```{r}
summary(cars)
```
You can also embed plots:
```{r, echo=FALSE, message=FALSE}
plot(cars)
```
So I think there are two posibilities.
You accidentally added it (perhaps by copying this template), or
It was removed in a previous version, as the latest version of Rmarkdown (2.9) does not produce this warning.
I suspect it's case 1, as I've never seen this output automatically inserted before.

When starting RStudio, this error appears. I can run several commands, but I can't compile anything in Rmarkdown. Does anyone know how I can fix it?
The error does not appear when typing a path to read from the file. It even appears when I try to compile an empty file in RMarkdown.
The error even appears with the default example script in RMarkdown.

## 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 content 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.
Trying to knit a doc into html, RStudio would hang on the conversion to html part. I looked around and it looked like this happened to other folks when they were using an out of date pandoc version. I updated pandoc to 2.8. I received the error in the title. Looking around again, it appeared that v 2.5 seemed stable. I installed that, restarted my computer, and still get the same error.
repex is the default example when you create an RMarkdown file in RStudio: file -> New file -> R Markdown -> html.

I have fixed this issue two months ago. Please make sure your rmarkdown version is at least v1.16. Once again, when in doubt, consider updating your packages:
update.packages(ask = FALSE, checkBuilt = TRUE)
I have an Rmarkdown document with a plot made with plotly and would like to generate an html file. It works when I click on Knit to HTML in Rstudio, but not when I run the following on the command line:
Rscript -e "require(knitr)" -e "require(markdown)" -e "knit('Untitled.Rmd', out='report.md')" -e "markdownToHTML('report.md', 'report.html')"
After this, I have a report.html file which contains the plot generated with plotly, but it is not interactive.
Does anyone know how to make it interactive with the command line?
Thanks
This is the code, btw:
---
title: "Untitled"
output: html_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

library(ggplot2)
library(plotly)
ggplot(pressure,aes(temperature,pressure))+geom_point(size=10,color='red')
```
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
```{r pressure_plotly, echo=FALSE}
g<-ggplot(pressure,aes(temperature,pressure))+geom_point(size=10,color='red')
ggplotly(g)
```
```{r}
sessionInfo()
```
Try:
Rscript -e "library(knitr); library(rmarkdown); rmarkdown::render('untitled.Rmd', output_file='report.html')"
Reasoning: knit seems to default to markdown output, and doesn't retain HTMLwidgets in the rendered markdown. Thus, when converting, you end up with missing files (you can see these errors if you remove echo=FALSE from the code block openings.
rmarkdown::render([...]) renders cleanly to HTML, avoiding the issues mentioned above. If you wish to specify the output format, you can do so using the output_format argument.
I'm getting started with rmarkdown and knitr. In the sample document provided by RStudio, I can successfully use render() to generate an HTML file that views fine in Chrome. However, when I click on the knit button, it generates a .markdown file and then returns the following error without rendering the preview:
Error generating HTML preview for ~/path/to/file/report.rmarkdown system error 2 (The system cannot find the file specified)
I think it's getting hung up at the pandoc stage. Is it possible that RStudio is looking for pandoc in the wrong place? Pandoc was already installed at C:\Program Files (x86)\Pandoc\pandoc.exe, but RStudio installed its own instance at C:\Program Files\RStudio\bin\pandoc\pandoc.exe, so maybe it's looking in the wrong place and/or confusing settings from one with the other?
Any help would be greatly appreciated. Thanks!
And just in case, here's the RMarkdown template I'm starting with:
---
title: "Monthly Report"
author: "Kris Shaffer"
date: "February 17, 2017"
output: html_document
---
```{r setup, include=FALSE}
library(knitr)
knitr::opts_chunk$set(echo = TRUE)
```

R version 3.3.2
RStudio 1.0.136
rmarkdown 1.3
knitr 1.15.1
pandoc 1.17.2 (both installations)
Turns out it was as simple as a file extension. I changed the filename from report.rmarkdown to report.Rmd. Knit works fine now.
I opened a new R Markdown file in R studio and got the default small working example.

It says, you only need to press the knit button to create an HTML
containg the text, the code and the results of the code. I got some long
error logs that were hardly helpful. Neither did changing the output to
PDF and Word - same result: text was there, code was there, no results of
running the code. By producing the output, the original file vanished.
What is wrong?
When the knit button is used on a file not yet saved, it asks you under which name to save it. The file needs to be saved as an Rmd file - just give no extension and R-Studio will do it right. Then, the file does not vanish and the resulting document contains the results of the r commands. I thought it asked where to save the output and gave it the extension of the output file, i.e., either myfile.html / myfile.pdf / myfile.doc.
In the chunk option try this:
{r, results='asis'}
summary(cars)
You can also embed plots, for example:
{r, echo=FALSE, results='asis'}
plot(cars)
The results = 'asis' command should output the tables and graphs if not please let me know.
