- R is made up of thousands of
functionsthat you use to manipulate and analyse your data. They are the equivalent to maths functions in Excel e.g. STDEV(), SUM(), MEAN()
- A collection of themed R functions for e.g. a data type, or an analysis type is called a
package - R has thousands and thousands of packages to integrate with propriety software (ArcGIS, Stata), other tools (Twitter, SQL) and multiple data types (.txt, .csv, .sav) including compressed file formats (e.g. NetCDF)
- Each function has a number of
argumentsthat are conditions for how you apply or run the function. All R functions follow the same format:Function_name(arg1, arg2, arg3...) R has a wonderful help file to show you exactly how to use each function and argument....it even gives examples for you to work through.
