R works with numerous data types. Some of the most basic types to get started are:
4.5 are called numerics.4 are called integers. Integers are also numerics.TRUE or FALSE) are called logical.Note how the quotation marks on the right indicate that "some text" is a character.
# Change my_numeric to be 42
my_numeric <- 42.5
# Change my_character to be "universe"
my_character <- "some text"
# Change my_logical to be FALSE
my_logical <- TRUE
> # Change my_numeric to be 42
> my_numeric <- 42
>
> # Change my_character to be "universe"
> my_character <- "universe"
>
> # Change my_logical to be FALSE
> my_logical <- FALSE
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
