Logical Type
Logical data type can store only two values: TRUE (or T) and FALSE (or F). These values are case-sensitive and are used to evaluate conditions and expressions.
Comparisons
Comparisons such as equality or greater-than tests produce logical results. These results are always either TRUE or FALSE.
Example
122 > 1 5 == 10
Type Conversions
- Number into logical:
0becomesFALSE, while any non-zero number becomesTRUE; - String into logical:
'F','false','False','FALSE'convert toFALSE;'T','true','True','TRUE'convert toTRUE;- Other values are converted into
NA;
- Logical into number:
FALSEbecomes0andTRUEbecomes1.
Swipe to start coding
- Assign the result of the expression
19*54 > 76*13to the variablelogic. - Show the value of the
logicvariable. - Show the data type of the
logicvariable. - Convert the
logicvariable to an integer and show the result.
Avoid using the print() function.
