Logical Operators R has an intuitive method for recoding variables, which relies on logical operators that return statements of TRUE and FALSE.A mathematical operator (such as ==, !=, >, >= <, and <=) takes two objects of equal dimensions (scalars, vectors of the same length, matrices with the same number of rows and columns, or similarly dimensioned arrays) and compares every element in the

Booleans (Logical Values) In programming, you often need to know if an expression is true or false.. You can evaluate any expression in R, and get one of two answers, TRUE or FALSE. When you compare two values, the expression is evaluated and R returns the logical answer: TRUE and FALSE are part of the R language, where T and F are global variables set to these.

The code can be abbreviated into a single line. Logicals. Logicals are a fundamental tool for using R in a sophisticated way. Logicals allow us to precisely select elements of an R object (e.g., a vector or dataframe) based upon criteria and to selectively perform operations.
