Each element of the first vector is compared with the corresponding element of the record vector.

The result of comparison is a Boolean value.

‘&’ à It is called element wise logical – OR operator , it compares both elements , it gives output TRUE if both elements are TRUE.

‘|’ àIt is called element wise LOGICAL OR operator ,it combines each element of the first  vactor with the corresponding element of the second vector and gives an output TRUE if one element is TRUE.

‘ !’ àit is Logical NOT operator , takes each element and gives opposite logical value.
