In RStudio, whenever I make a new Markdown it always has default code. How do I remove it?
Here's the code that shows up.
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## R Markdown
This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.
When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
```{r cars}
summary(cars)
```
## Including Plots
You can also embed plots, for example:
```{r pressure, echo=FALSE}
plot(pressure)
```
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
Every time, when creating a Rmd file, Rstudio will open a Rmd template:
https://github.com/rstudio/rstudio/blob/822e558c7a274de464f992f69e3acee2fde5ab04/src/cpp/session/modules/SessionRMarkdown.R
# given a path to a folder on disk, return information about the R Markdown
# template in that folder.
.rs.addFunction("getTemplateDetails", function(path) {
# check for required files
templateYaml <- file.path(path, "template.yaml")
skeletonPath <- file.path(path, "skeleton")
if (!file.exists(templateYaml))
return(NULL)
if (!file.exists(file.path(skeletonPath, "skeleton.Rmd")))
return(NULL)
# load template details from YAML
templateDetails <- yaml::yaml.load_file(templateYaml)
# enforce create_dir if there are multiple files in /skeleton/
if (length(list.files(skeletonPath)) > 1)
templateDetails$create_dir <- TRUE
templateDetails
})
Hence the simplest solution would be:
go to xxx\RStudio\resources\templates folder, where your
Rstudio installed
open r_markdown_v2.Rmd file, and delete
everthing
save it
Now, everytime, when you open a rmarkdown, you can have just the yaml part.

How can we export multiple markdown files (HTML, PDF, WORD) from R into zip file. Many thanks for your help!
Suppose, we have the following Rmarkdown file (the source file) which can be rendered as pdf, html and word documents.
multiple_output.Rmd
---
title: "multiple outputs"
output:
word_document: default
html_document: default
pdf_document: default
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## R Markdown

```{r cars}
summary(cars)
```
## Including Plots
You can also embed plots, for example:
```{r pressure, echo=FALSE}
plot(pressure)
```
Now to render this source file to pdf, html, and word document at once and then zip it into a folder, we run the following code from another Rscript file (rscript file needs to be in the same place where your Rmd source file is)
file.R
# create a folder where the multiple output files will be placed
dir.create("multiple_output")
# then render the source file to that created folder
rmarkdown::render(
"multiple_outupt.Rmd", output_dir = "multiple_output/",
output_format = "all"
)
# create file paths for zipping
files_for_zip <- dir('multiple_output', full.names = TRUE)
# zip the folder
zip(zipfile = "multiple_output", files = files_for_zip)
Then we will have the zipped folder multiple_output.zip.
As the example, if you create a new R markdown file and save it as 'test'. Can one then run or deploy this test.Rmd file from within a normal R script. The purpose being to generate the output in HTML, without having to open the .Rmd file.
I'm hoping to create one master file to do this for many markdown files in one go; which would save considerable time as you then don't have to open many markdown files and wait for each one to complete.
You are looking for rmarkdown::render().
Contents of "test.Rmd"

title: "Untitled"
output: html_document

```{r setup, include=FALSE}

cwd_rmd_files <- list.files(pattern = ".Rmd$")

Thanks the-mad-statter, your answer was very helpful. The issue I faced, required me to prepare markdown dynamically. By adapting your code, that's easily possible:
Contents of "test_dyn.rmd"
---
title: "Untitled"
output: html_document
---
The chunk below adds formatted text, based on your inputs.
```{r text, echo=FALSE, results="asis"}
cat(text)
```
The chunk below uses your input in as code.
```{r results}
y
```
Contents of "script_dyn.r"
in_text <- c("**Test 1**", "*Test 2*")
in_y <- 1:2
lapply(1:2, function(x) {
text <- in_text[[x]]
y <- in_y[[x]]
rmarkdown::render(input = "test_dyn.rmd", output_file = paste0("test", x))
})
Like this you can create files with different text and different variables values in your code.
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)
```

You can also embed plots, for example:
```{r pressure_ggplot, echo=FALSE}
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 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.
