Atom editor - convert line endings to UNIX - atom-editor

I need to convert the line endings of some mock data into Unix format. I'm using Atom editor on Win 7.
Looking online, I found an Atom package to convert line endings, but the package said it is deprecated since Atom now has this as a standard feature.
I cannot find any such standard feature in Atom - and Atom's documentation doesn't even know what line-ending conversion is.
'About Atom' tells me Atom is up-to-date with v.1.23.3
This, to me, seems a paradox.
(And no, I cannot just use Notepad++.)
I've looked around at a lot of solutions, but have not found one that will actually work.

The built in line-ending-selector package supports this use case: https://atom.io/packages/line-ending-selector
The package's documentation describes how to do this:
You can click the line ending in the status-bar to open a modal with the line ending options. Selecting a different line ending will change each line of the file in the active editor.
If you prefer to use the keyboard, you can also open the command palette (cmd-shift-p on macOS), type Convert and then use the Line Ending Selector: Convert to LF and Line Ending Selector: Convert to CRLF commands from there.

Go to Preferences under Atom menu. Uner the settings window, go to Packages. In packages search on line-ending-selector. This reveals a core package that is loaded with Atom. Scroll down the line-ending-selector page and you see the header Settings. Below that you can choose the default line endings. You can choose LF, CNTL-LF, or OS. Set this to the value you want.

Where is convert in ImageMagick?

I just spent an infuriating day trying to make a gif out of a series of jpg files in R. I installed ImageMagick to run the following code:
system("convert -delay 40 *.png example_4.gif")
but I get the following error message:
Warning message:
running command 'convert -delay 40 *.png example_4.gif' had status 4
which looks like a path error. Now I've looked for convert in the Imagemagick download and can't see it anywhere. Does anyone know where it is?
Alternately, is there another easier method of making a gif from a series of jpegs in R that isn't ridiculously long?
Thanks
Three options:
Consider using the magick R package instead of using system().
Change your script from convert ... to magick convert ....
Re-install imagemagick, and enable the "Install legacy utilities (e.g. convert)" option.
This change has been around since 7.0.1 (now up to 7.0.7), and is discussed in their porting guide, specifically in the section entitled "Command Changes".
Philosophically, I prefer to not install the legacy utilities, mostly because it can cause some confusion with command names. For instance, the non-ImageMagick convert.exe in windows tries to convert a filesystem ... probably not what you want to accidentally trigger (there is a very low chance that you could get the arguments right to actually make a change, but it's still not 0). The order of directories in your PATH will dictate which you are calling.
EDITs:
From comments, it seems like the difference between "static" and "dll" installers might disable the option to install legacy utilities such as convert.exe. So you can either switch to the "dll" to get the legacy option, or you are restricted to options 1 (magick R package) and 2 ("magick convert ...").
From further comments (thanks to fmw42 and MarkSetchell), it is clear that the old convert.exe and the current legacy mode of magick.exe convert are not the same as the currently recommended magick.exe (without "convert"); the first two are legacy and compatibility modes, but they do not accept all arguments currently supported by magick-alone. So the use of "convert" anywhere in the command should indicate use of v6, not the current v7. This answer is then merely a patch for continued use of the v6 mechanisms; one could argue a better solution would be to use magick.exe's v7 interface, completely removing the "convert" legacy mode.

Github atom editor shows line deleted and added back

I am using Github's atom text editor.
Most of the times, when I modify a single line in a file, git diff shows a lot of lines as deleted and added back in this way
- #op_contact = "Not Available"
+ #op_contact = "Not Available"
This causes inconvenience in code-reviews and hence I am forced to use other editors like SublimeText.
It looks like some simple setting should fix this, but I am not sure how to do it and I don't know what to search for. There are some related questions, like this one but I want to fix it from Atom editor, as this problem is not present in SublimeText.
Atom version: 1.3.1
You are probably searching for the Whitespace package which ships with Atom by default.
It removes unnecessary whitespace at the end of each line. Disable it and your suspicious line changes should be gone.

Print with syntax color in R-Studio

In R I always like to print out the script since it gives a good overview and one can adjust eventual errors. I like the syntax highlighting in R-Studio because it facilitates reading and fast comprehension of code.
Is there a way to print out the text with the highlighting I see in the editor?
Its not an R-Studio solution, but notepad++ will print R source with syntax highlighting.
RStudio will not print in colour, but it's easy to save the code as a PDF; in this case the syntax format is preserved. My favourite package is knitr.
library(knitr)
stitch("file_name.R")
The default output is PDF/Markup in .tex. If you prefer not to typeset, running the below will export as .html
stitch(script="file_name.R", system.file("misc", "knitr-template.Rhtml", package="knitr"))
Brief explanation
The reason this is an answer to this question in because of the last line of the question:
Is there a way to print out the text with the highlighting I see in
the editor?
so we are not limited to only and only using Rstudio software here.
After exploring the awesome answer by #rrg and realizing that it runs the code line by line, I wrote a comment below his answer and continued googling. My problem is that the code I wrote is so large and so time consuming to run that running it for the sake of having a syntax highlighted version is not feasible.
Most of the solution out there online involves having notepad++ which is a Windows application and I'm a dedicated Linux user, so I searched for a way I can do this in Linux (and possibly Mac)
The way I solved it:
Inspired by a blog post, I used the famous and beloved Vim to convert R to syntax highlighted HTML and then because you can open HTML in your browser, you can what ever you want with it (print, screenshot, etc.)
Activate synax highlighting in Vim:
open terminal
then open the vim config file by typing vim ~/.vimrc
press i from keyboard to go to "insert mode"
go to the end of the file using arrow keys on your keyboard
type syntax on at the end of the file
now you need to save and exit. For this you need to press Esc button from keyboard to come out of "insert mode" and then type :x and press Enter to save and close the file.
if you want to change the color scheme of the syntax highlighting, visit the bottom part of this website
From terminal open your file with Vim:
vim YOUR_FILE_PATH
Having you R code open in vim, you can turn on the line numbers if you like by pressing Esc and then write :set number and press Enter.
For converting R to HTML, press Esc to make sure you are not in "insert mode" and then type :TOhtml and press Enter. This will result is having a split window in terminal, half is your R code and the other half id your new HTML code.
For saving the files, type :x along with Enter button from keyboard twice to save both files (your R file will be unchanged if you have not typed anything extra in it and your HTML file will be created with the same name near your R code)
Now open it with your favorite browser (in my case Vivaldi) and do what ever you want (in my case converting the whole HTML into PNG)
Best way:
download https://github.com/jaredpetersen/codeprinter and paste in the r code. then choose syntax highlighting Xcode
For those using a Mac (and thus without access to Notepad++) cutting and pasting into Xcode and printing from there will also work.
As with Ron Jensen's earlier comment, this isn't an R Studio solution, but in the interests of "just getting it to work", I hope this helps someone.

Multimarkdown in GitHub's Atom editor - made a start, want to make more progress

To extend the basic Markdown support in Atom, I've converted the TextMate Multimarkdown bundle (unescaping one hash sign - see the process on this Atom discussion). The (converted) TextMate bundle files are now in my Atom config folder.
Markdown syntax now highlights okay (and differently from the built-in GitHub Markdown) when I choose 'Multimarkdown' from the syntax list. The table sytnax appears to pick out table heads, but there's no preview and no support for definition lists.
Can someone point me to the file(s) in Atom I'd need to work on to get:
a preview pane?
syntax highlighting for definition lists?

Installing program (dot) on system search path in R

I'm a social scientist having a hard time struggling through the technical instructions for integrating the graphing program dotdocumented here with the sem package documented here.
I have successfully run the command pathDiagram in the sem package, which outputs code that is presumably supposed to be read into dot. The documentation for the sem package says
"To obtain graphics output directly, the dot program must be on the system search path."
I'm sure that this is a totally mundane question, but I'd really appreciate help. I'm lost.
In R execute this command:
Sys.which("dot")
This will tell you whether a system call will be able to find your 'dot' installation. You did install 'dot', right?
The Graphviz pkg file for MacOS greater than or equal to 10.6 (and your ML is 10.8) can be obtained from AT&T labs: http://www.graphviz.org/Download.php
After installing from its .pkg file (with the same Graphviz version 2.30.1 on OSX 10.6.8) I get:
> Sys.which(c("dot"))
dot
"/usr/local/bin/dot"
This does NOT open up dot. It merely confirms that the dot program can be found on by R. Running the first example on hte ?pathDiagram page only outputs a source file to the console which could be used for dot to the console, because no file argument is given, but if you add a file argument it creates a pdf file using dot with a message to the console screen:
pathDiagram(sem.dhp, min.rank='RIQ, RSES, RParAsp, FParAsp, FSES, FIQ', file="test",
max.rank='ROccAsp, REdAsp, FEdAsp, FOccAsp', output.type="graphics", graphics.fmt="pdf")
#Running dot -Tpdf -o test.pdf test.dot
This produced a file in my working directory that could be viewed with Preview.app. If you want to use dot on its own, you will need to read its manual and follow the instructions for using it in a standalone manner.
Update as per comments:
If when you type which dot in terminal, you get a response with a path, then it is safe to say that graphviz is installed.
As per pathDiagram's manual (ie, ?pathDiagram), it is not intended to return a value.
Instead, use the file argument to specify where to save the output to.
pathDiagram(model=SomeModelInR, file="path/to/file", ...)
This seems to be more of a general mac os x question, but anyway, here we go:
In your applications > utilities folder, open up terminal.
(i'm assuming dot is called dot if not please modify accordingly)
Type which dot
- this will show you the path to dot, perhaps something like /usr/bin/dot
- in this case, the path you are looking for in the next part is /usr/bin
Type echo $PATH
- this will show you several paths separated by :
- If the path you got with which dot is listed as one of those paths, then you are all set.
- If not, please see the link below on how to modify
