R Operators

This lesson is part of R · All levels

Summary

This lesson reviews the various operators groups in R. R distinguishes the arithmetic operator (+, -, *, /, ^, %%, %/%), the comparison operator (==,!=, <, >), as well as the logic operator of single elements (&, ̊) and short scalar-evaluations (&&, ||). In addition, there is a range operator ':' and a matrix special operator '%*%'.

Key points

The operator '^' is used for the exponential ranking
The operator '%%' is the modulus, and '%/%' is the integer division
The colon operator ':' creates a sequence of numbers (e.g.: 1:5)
The operators '&' and 'b' operate on vector elements, while '&&' and 'b' scalars operate on a single element
