Relational Operators

Description

Binary operators which allow the comparison of values in vectors.

Usage

x < y
x > y
x <= y
x >= y
x == y
x != y

Value

A vector of logicals indicating the result of the element by element comparison. The elements of shorter vectors are recycled as necessary.
Objects such as arrays or time-series can be compared this way provided they are conformable.

Note

Don't use == and != for tests, such as in if expressions, where you must get a single TRUE or FALSE. Unless you are absolutely sure that nothing unusual can happen, you should use the identical function instead.

Examples

x <- rnorm(20)
x < 1
x[x > 0]
