I am trying to do some work for my thesis which has me using the R programming language (and the R app on Mac OS Lion) for the first time. I had to download the files from here to work with but none of the files comes in .rda or .r they all come in different file extensions. Can someone please tell me how to either convert or use these files?
This page might be relevant to your interests. Also note that if you click on the link on that page that says "Analyze with GEO2R" you can get an R script created for you that will do some of the legwork for you. I would highly suggest reading the instructions on that page in order to get things prepared the way you want them to be.

I am currently working on a coding project and I am running into trouble with how i Should import the data set. We are supposed to have it read in a way so that our instructor can access our markdown file and be able to import the data and run the code without changing file paths. I know about using relative file paths to make it accessible to anyone, however I don't know how to get around the /users/owner part of the file path. Any help would be greatly appreciated and if you have any further questions feel free to ask.
I've tried changing the working directory to a certain folder that both I and my instructor have named the same thing, however, like I said above, when I use read.csv to import the data frame I am still forced to use the /users/owner filepath which obviously is specific to my computer.
I can understand your supervisor, I request the same from my students. My recommended solution is to put both data and R script (or the .Rmd file) in the same folder. Then one does not need to add a path in the read.csv (or similar) function.
If you use RStudio, move to the folder in the Files pane and then use the gear icon and select "Set as Working Directory".
Then send both files (.R or .Rmd) and the data to the supervisor, ideally as a zip file. The supervisor can then unpack it to an arbitrary folder and just double click to the .R/.Rmd file. The containing folder will then automatically become the working directory.
Other options are:
to use a subfolder for the data or
to put the data to a publicly readable internet location, e.g.
Github and read it directly from there.
The last option requires of course that the data have a free license.
I've recently started to use the Atom editor again because it offers some good features.
However it doesn't recognize the code in my files most of the time.
I use it mainly to look through SSIS files - meaning they are in XML-format but have other file endings like ".conmgr" or ".dtsx". Yet they all start with <?xml version="1.0"?>.
Now to my question:
Can I somehow set the standard language from "Auto Detect" to "XML" or is there any package so that Atom starts to recognize those files as XML-code?
Since this is my first time using stackoverflow to ask something I hope I've done everything right.
Thank you in advance!
The two picures show two different files. Both ending on ".conmgr":
This file it does recognize
This file it doesn't
I am new to the use of version control in RStudio. I would like to know what is the optimal way to do this:
I have a R project, and I can give one version of the project to a coworker.
Then he will modify some files (and me too).
When he gives the folder back to me, is there is simple way to compare two files and decide which which lines go to the final version?
The usual workflow for comparing files using builtin Rstudio is through version control tools such as git or subversion.
Your process is more "I give you the content of the project folder, make whatever you want and give it back to me" then "you want to know what have changed between your copy and his".
Rstudio won't help you in this case. You'd better use merge tools such as meld, winmerge, .. that will spot the differences between files and their content and allow you to copy changes in either way (from you to him or him to you)
I am developing some tool by make use of python 3.4.2 shell. But i stopped while dealing with file pointers in python. Basically what i am doing is merging the file with another file. I came across scenario, wherein i will search for a string in the file, the other file content i need to merge should start from that string. So please could anyone suggest me on this??

I'm trying to write some programs to download a lot of economic data (on the order of hundreds of distinct tables from different websites, that'd need to be updated frequently). Take this website:

I want an R program to be able to click on one of those little green buttons that will download an xls file, so I don't have to click it by hand. Is there a package / function in R for this type of thing? (And if not, is there another simple-ish way to do it?)
Thanks!
The buttons just link to .xls files. So, you could use the URL of the page that the button points to, and use that URL as an input to a script / function that does the scraping. There are plenty of packages like rcurl that you could use to manage the download.
