In the first module we looked at the field experiment as described by the domain scientist and we also looked at the data from the perspective of the analyst. In this module we will learn how to install the R software then we will explore a few basics of data files that are generated by sensors and data loggers. We will also take a quick tour of tools that may be used to look at the raw data.
We will then develop a methodology that may be taken with respect to preparing raw data for a computation that helps us analyze. Finally, we will look a few "data types" that are typically used in R.
After completing this lesson, you will be able to:
- Install the R software on your computer
- View raw data using simple text editor
- Develop a methodology with respect to preparing raw data for analysis in R
- Describe the concept of vectors, list and tables in R
