The course is part of this learning path
This module looks at how to control data in R, through reading, writing, and loading objects.
The objectives of this module are to provide you with an understanding of:
- How to bring in data from a file in R
- Saving and loading objects in R
- Interacting with the clipboard
- How to connect to files in R
- How to read from a file in R
- How to write to a file in R
Aimed at anyone who wishes to learn the R programming language.
No prior knowledge of R is assumed. You should already be familiar with basic programming concepts such as variables, scope, and functions. Experience of another scripting language such as Python or Perl would be an advantage. An understanding of mathematical concepts would be beneficial.
We welcome all feedback and suggestions - please contact us at firstname.lastname@example.org to let us know what you think.
[Instructor] We can interact with the clipboard in R using two functions. Firstly, the write clipboard, and secondly, the read clipboard. The write clipboard function will allows us to copy to the clipboard. Let us note that the clipboard can only contain character vectors. So, here is a piece of data that I've created, a matrix. If I was to write this out to the clipboard, I would need to use the as character function to convert data into something that is applicable inside the write clipboard. I can paste this using the edit paste command or control V. And it show you that I have created a character vector and store this in the clipboard. I can use the read clipboard function, read, clipboard, function, to paste this data into R. I can store this as clip and I can show you what I have brought in. I've brought in a character vector. In order to return it back to the original data matrix. I would need to then convert this back into the matrix using the matrix constructor. And as you can see on the screen, clip now equals data, even though it left the R studio session into the clipboard and returned back via the read clipboard function.
