If asked before, I apologize, but I can not find an example online or any other place Used to be.
I have a dirty data file in a text file (it can be a JSON). I want to analyze the data in R, and because I'm still new to the language, I want to read in raw data and want to manipulate it from there.
How do I go about reading a text file on my machine in JSON? In addition, if it is not JSON, how can I read raw data (as read in columns, etc.), then I can go ahead and understand how to parse it essentially?
Thanks in advance!
If you want to use JSON related packages in R, then there is a number answer on it On other posts I think you have already searched on this site at JSON [r] , there is a lot of information in it.
If you want to read line and process in text file line later, you can either use scanned () or readLines () You can. They do the same thing, but there is an important difference between them.
Scan () lets you decide which type of items you want to find, how many and how many. You can use the scan to read the help file such as scan (file name, "") for more information as a component of a vector in each word / number / symbol Are there. You can also use a specific delimiter to isolate the data. See also examples in help files.
To read the line from the line, you readLines (file name) or scan (file name, "", Sep = "\" n ") This gives you a vector in the form of elements in the form of files. This again allows you to do custom processing of the text. Again, if you really have to do this often, then you want to consider doing it in Perl.
