With Rstudio you can add customized snippets but always they should be triggered using TAB or SHIFT-TAB depending on if you are in R or Rmd file.
Is it possible just to trigger the snippet by typing the sequence of characters?
For example, just by typing dm it will create an equation environment without the TAB or SHIFT-TAB intervention.
I'm thinking in something like this especially for typing documents fast with a lot of math and code mixed.
Thanks for any help!
According to the RStudio devs this feature is not possible right now.

I am looking for a way to 'auto save' my code each time i run it. I figure the best way to achieve this would be to write code in my models which will overwrite and save the file which is open. I have been experimenting with:
rstudioapi::documentSave(rstudioapi::getActiveDocumentContext()$id)
However, I have not had any success.
Good Morning All,
I worked out the issue. The model I am working on generates tables, which are produced with View(). This means when the code is finished running the script is not the tab displayed.
documentSave()
Will only save the script which is open. Therefore, it is advised that you should consider using
documentSaveAll()
Which will save all tabs open.
I'm quite lost... I'd like to add a save-button to my shiny/flexdashboard-app. First I tried to use 'shiny files' but it seems that this doesn't work with rmarkdown somehow.
Is there another possibility to create a decent "save-to"-Dialog (like a dialog opens up, one can choose the path and set a filename, hits OK and the file gets saved (the saving-part is no problem))?
Any help is highly appreciated.
Best Regards
Daniel
A combination of downloadButton() (or downloadLink()) and downloadHandler() should also work in flexdashboard. You can find the documentation here.
I'm sharing a small but annoying issue that sometimes pops up when I'm using shortcuts to insert operators while working on a markdown file in R : the operator either does not get written, or even worse gets written on another file.
So let's say I am working on the file "report.rmd", and I want to insert the pipe operator using Ctrl+Maj+M, or the assignment operator using "Alt+-", and I have the file "test.R" opened. Well, I therefore type the aforementioned shortcuts and...nothing happens on my markdown file. But some nice operators that had nothing to do there get written on my test.R file.
The only way I found to solve this problem is to close and reopen RStudio (restarting unfortunately doesn't solve the issue).
While this is quite a minor problem, it's incredibly annoying. Did it ever happen to anyone of you, and if so do you know where it comes from and how to solve it?
Edit:
Although I am still running into this issue (without being able to reproduce it consistently) I came into a somewhat lighter solution. Instead of restarting R, simply closing all tabs (closing just the problematic one doesn't work) solves the problem. I hope this helps narrowing down the possible origins of the problem.
Short Answer
re-define the key combo to Ctrl+Shift+ \ , assuming this does not create a conflict
Background
I've had a similar problem for a while, too. In my case, the shortcut never works. I can not find the source. I even found a conflict with Ctrl+Shift+M assigned to 2 Editor functions.
Image:Screen Capture 2 conflicting hotkey assignments
However, a simple key reassignment of the one that is not the pipe operator ("Expand to Matching")
Image:screen capture showing the hotkey conflict solveddidn't solve the issue in my case.
Solution
Here's what did the job for me
I managed to assign a different combo (that hasn't been assigned yet) and that is comfortable enough in the sense of its location on the keyboard
go to Tools → Modify Keyboard Shortcuts...
In the filter box, write "Pipe"
Direct the cursor to the text box showing the current shortcut, and press the new combo (e.g. Ctrl+Shift+ \ ), then Enter.
Remember to hit Apply
Make sure the new Combo isn't a duplicate of another command, by going back to step 1 and sorting the list by Shortcut, then scrolling down to find your new one. if there is an ovelap, consider changing one of them.
Anyone know how to set Notepad++ as default text editor for SAS, Stata and R?
I'm having the hardest time finding anything online (particularly for SAS). Looking for ability to run code from Notepad++ as well as setup color coding.
Thanks.
Why not just go the GUI route: right click, e.g., any foo.R file and select "Open with...", then pick Np++ and click the "always open this file type.." button. Rinse, lather, repeat.
BTW, for R, if you don't already have it, get "NppToR" , a little app which lets you execute code directly from the Npp window.
On windows you can either:
manually edit the keys for the file type to set the value of HKEY_CLASSES_ROOT\FILE_TYPE\shell\edit\command where FILE_TYPE is the appropriate one for each of the files extensions you wish to change this is quite hard work or
you can use a program that does it for you such as the free Default Programs Editor
In either case the first thing to do is to back up the registry.
I would seriously suggest looking into using one of the many, some free IDEs as they will automatically include the run from edit environment, syntax highlighting, code completion and, in many cases, debugging as well.
Notepad++ is my favorite editor and I was in the same shoes as you are now.
I am assuming that you are in Windows (Notepad ++ doesn't exist in Mac, saddest thing for me)
Please follow the steps mentioned in the below webpage and do as the author says.

Now for in-line editing , it may be not be the best choice for SAS. Although I haven't tried it much so not a good person to comment on it.
I am getting started with the reproducible research tools in R, and I'm pretty excited about the prospects. Sweave/Knitr/Markdown, all that stuff is great. I use RStudio, and they have done a great job of integrating those tool, and I hear that StatET does a nice job putting all that together as well.
I don't write academic papers in LaTeX, and all the people I work with use Word, so I am very interested in an effective workflow to use ODFWeave to make documents.
My usual process is:
Develop the code chunks in my IDE (RStudio, in my case)
Go back and insert these into a ODT document and fill in the surrounding text.
run ODFweave
My problem is that I get confused in tracking code chunks and putting them into the ODF document. Keeping the ODF document in sync as I create the code is annoying, so I'd rather wait and insert the code chunks by name.
So finally, here are my questions:
What are people's suggestions for tracking code chunks or on how to optimize this workflow?
Can anyone recommend tools or tips for keeping track of the code chunks you write?
Being a software geek and a data nerd, I naturally imagine a piece of software doing this for me. Like I'd have a database of code chunks, and when writing the ODF document I'd be able to click on a chunk to insert it into my ODF file.
Has one anyone created this sort of thing?
When you check the number of items tagged odfweave on SO, you will notice that it is rarely used compared to Sweave and knit-offs. I do not fully understand why it did not take off, possible because of table-generation being such a nuisance (at least that what I remember from my attempts).
Since many customers insist on Word-Documents, we are using two alternatives currently:
Create html, e.g. with RStudio/knitr/rmd, and read it with Word. This is not really a good workflow, to get reasonable document you need much manual post-processing, but it works more or less.
You can also use the path via RDCOM. I don't remember what's the state of art here, because we have totally given up using it since the conditions of licensing were not transparent to us.
Use pandoc. This approach produces documents that do not need manual post-processing in MS-Word, but the range of features to create a nice layout (cross-linked images, figure numbering) are limited; it might be a problem that we are not yet good enough in using pandoc in its full.
