Zero is considered FALSE and non-zero numbers are taken as TRUE. Operators & and | perform element-wise operation producing result having length of the longer operand.īut & and || examines only the first element of the operands resulting into a single length logical vector. Logical operators are used to carry out Boolean operations like AND, OR etc. Longer object length is not a multiple of shorter object length > x y x+y # Element of y is recycled to 9,4,9,4 R will issue a warning if the length of the longer vector is not an integral multiple of the shorter vector.

When there is a mismatch in length (number of elements) of operand vectors, the elements in shorter one is recycled in a cyclic manner to match the length of the longer one. We can use the function c() (as in concatenate) to make vectors in R.Īll operations are carried out in element-wise fashion. The variables used above were in fact single element vectors. The above mentioned operators work on vectors. Here is a list of relational operators available in R. Relational operators are used to compare between values. Here is a list of arithmetic operators available in R. These operators are used to carry out mathematical operations like addition and multiplication. Type of operators in R Arithmetic operators Operators in R can mainly be classified into the following categories. R has many operators to carry out different mathematical and logical operations.

R and
