Note that binary operators work on vectors and matrices as well as scalars. Here is the basic idea: a <- 3 x <- "a > 2" if (x)TRUE.
The Logical-R Joint Venture LLC has 2 total employees across all of its locations and generates $170,191 in sales (USD). In R, the operators “|” and “&” indicate the logical operations OR and AND. For example, to test if x equals 1 and y equals 2 we do the following: > x = 1; y = 2 > (x == 1) & (y == 2) [1] TRUE. However, if you are used to programming in C you may be tempted to write
Base R also provides the subset () function for the filtering of rows by a logical vector. Consider the following R code: subset (data, group == "g1") # Apply subset function # x1 x2 group # 3 a g1 # 1 c g1 # 5 e g1
An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. R language is rich in built-in operators and provides following types of operators. Types of Operators. We have the following types of operators in R programming −.

All four are logical (1) vectors. Logical vectors are coerced to integer vectors in contexts where a numerical value is required, with TRUE being mapped to 1L, FALSE to 0L and NA to NA_integer_. Logical Values in R. There are only two logical values, TRUE and FALSE. They can be interpreted as yes/no, on/off, satisified/not satisfied, or any option corresponding to a binary choice. In R, if desired, we can abbreviate TRUE with T and FALSE with F. Logicals often indicate if a given condition is true or false.
