Join Barton Poulson for an in-depth discussion in this video Reading data from a spreadsheet, part of Learning R.
R is a flexible program that allows you to get data into it in many different ways.…I'm going to start in RStudio here, and I'm going to open up the script that I…wrote for this movie by clicking on open existing File, by going to Exercise…Files, and opening Exercise 02_04.…We're going to try opening a single dataset in several variations, through…several different routes that researchers would commonly use.…The simplest, but not necessarily the fastest way to get data into R is to enter…it in directly using the editor.…
So, for instance, on line 4 here, I'm going to create a variable called x, and…then I have the assignment, that's the arrow, and then I'm going to assign the…numbers 0 through 10 into x.

The course continues with examples on how to create charts and plots, check statistical assumptions and the reliability of your data, look for data outliers, and use other data analysis tools. Finally, learn how to get charts and tables out of R and share your results with presentations and web pages.
