I'm utilizing a Macbook pro running "El Capitan" and RStudio is version 0.99.902. I'm writing a Rmd document. I want to utilize the snippets that RStudio has built in and create my own also. By clicking Preference => Code; I can see that "Enable code snippets" is checked. However, while trying to utilize any snippet the completion is not performed. If I typed just r I should get this block of code, but nothing hapen
snippet r
```{r ${1:label}, ${2:options}}
${0}
```
I also create a simple snippet:
snippet dthen
%>%
None of the markdown snippet seems to work. Do I'm doing something wrong or any setting has to be done?
You can invoke code snippets in Markdown in RStudio using Shift+Tab after typing the snippet, but it will not currently prompt you to expand the snippet, either with Tab or by just waiting. I thought this was a bug, but the discussion in this GitHub issue says it's intended, just still-to-be-documented.
In Tools > Global Options > Code > Editing > Edit Snippets, go to the section "Markdown" and paste your snippet there. Save, OK, apply. Type r in your Rmd document (not within in a R code chunk) and click Shift+Tab. If it still does not work, try to create a new "R markdown" file (File > New file > R markdown) and check if it works there.

In R Markdown if I have a chunk coded with the normal r chunk wrappers,
```{r}
[R code]
```
A play button will appear. However, when I run a chunk wrapped like so for other language engines:
```{python}
[python code]
```
or replacing python replaced with bash/sh, I don't get a play button on the right.
Is there a package I need to install? I restarted Rstudio, and even downloaded the Lesson 5: https://rmarkdown.rstudio.com/lesson-5.html , which even shows those play buttons, and I still don't get it. I am on a mac, and saw that someone on a Windows computer was able to see the play buttons.
I think you need to install the package "knitr". Try to check that first.
Second, you might need to state explitly where your interpreter for Python is, for instance. Use
{python, engine.path = '/usr/bin/python3'}
YOUR CODE
to see if it works.
How can I force RStudio (v1.1.383) to evaluate R chunks always in console (instead of inline) when working with Rmarkdown documents, using a script?
I know I can set up Output chunks in Console by clicking on it:
According to this RStudio support post I could also un-check 'Show output inline for all R Markdown document' under 'Tools -> Global Options...':
But, is there a way to do it from a command line?
The reason I ask is that, I often work on my university machines and they all restore to defaults after each reset. Each time when in class, we have to manually go thru menus.
Knowing how to do it via a console command would as useful as starting each of my classes with
rm(list=ls())
There's not currently an elegant way to do this. This preference is stored inside an internal RStudio state file, in %localappdata%\RStudio-Desktop\monitored\user-settings. If you're sufficiently motivated you can write a script which sets the rmd_chunk_output_inline preference, but it's going to be unpleasant.
One thing you can do is set the chunk output type in the YAML header, like this:
---
editor_options:
chunk_output_type: console
---
You could also use an R Markdown document template with this set up for you (maybe your script could write this out).
Finally, there's an open issue for this on RStudio's github page which you might comment on and/or vote for:

I would like to test code parts in my R Markdown code without leaving Sublime Text.
For instance:
Multiplying the grades with two solves the unreliability problem:
```{r}
chisq.test(2*grades)
```
In the above example, I would like to select the line that has the code "chisq.test(2*grades)", press my key combination, and have it ran in SublimeREPL as R code.
However, when I try this, I get the following error from SublimeREPL:
Cannot find REPL for 'HTML.markdown.rmarkdown'
When I change the syntax through view menu to "R" (rather than R Markdown), the code runs fine. This is a workaround though, and it is undesirable because it costs me R Markdown syntax highlighting.
I suspect the solution is simply copy-pasting a few lines of SublimeREPL package code and repurposing them for R Markdown, but I was unable to achieve any results yet. I'd appreciate any help.
From this answer :
Open the file SublimeREPL/config/R/Main.sublime-menu. Its default position depends on your system
Linux: ~/.config/sublime-text-3/Packages
Mac: ~/Library/Application Support/Sublime Text 3/Packages (untested)
Windows: %APPDATA%/Sublime Text 3/Packages (untested)
Add your scode to the option "additional_scopes":
"additional_scopes": ["HTML.markdown.rmarkdown","tex.latex.knitr"],
Save the file, close the REPL tab, restart sublime, and open a new REPL instance.

Ufff... I believe I did my hw to research this and still don't have an answer so asking all:
I have R-Studio, valid RMD file, when I tried to I don't get new .pdf file, I have viewer which is still html.
No problem to create HTML, it works fine, but I need pdf.
tried to use render ("file.RMD", "file.PDF") to find that I don't have render, tried install pandoc, got an error < package ‘pandoc’ is not available (for R version 3.1.2)>
so what is the simple way to get that pdf, why my doesn't work as desinged? what I'm missing I put that info into header too...
output: pdf_document
Im totaly lost, appreciate help.
render("Proj1.RMD", "Proj1.pdf")

I have an RMarkdown file that I use to generate a nice HTML report.
The problem is, I want to be able to automate it so that it can run on a headless server. As such there will be nobody there to start Rstudio and press the 'knithtml' button and it seems that Rstudio is doing a LOT of additional magic like having it's own version of pandoc, running all the necessary commands, applying css styles etc.
How can I take this report and generate the same thing Rstudio is generating when I press the 'knithtml' button, but by just running an R script?
Thanks.
Try using
rmarkdown::render("/PATH/TO/YOUR.Rmd", output_file="/PATH/TO/YOUR/OUTPUT.html")
instead. This assumes you've got the rmarkdown library loaded on your headless box. It will use the system pandoc, but make sure it's 1.12 or higher.
Here's what knit2html does (via the "R Markdown" tab near "Console"):
Here's a side-by-side. Left is clicking the button, right is running the command:
I had the same issue. After a lot of brute force, I got the same result as RStudio with this command line:
"path\to\Rscript.exe" -e "rmarkdown::find_pandoc(dir='path/to/RStudio/bin/pandoc'); rmarkdown::render('file.Rmd')"
