Exercise

Some of R's most basic types to get started are:

• Decimals values（有小数点的数字） like 4.5 are called numerics.

• Natural numbers（自然数） like 4 are called integers（整数）. Integers are also numerics.

• Boolean values（布尔数学体系的值） (TRUE or FALSE) are called logical.

• Text (or string) values are called characters.

Note how the quotation marks on the right indicate that "some text" is a character.

Instructions

Change the value of the:- my_numeric variable to 42.- my_character variable to "forty-two". Note that the quotation marks indicate that "forty-two" is a character.- my_logical variable to FALSE.

Note that R is case sensitive!
