Basic vector types

This is an “RNotebook” for integrating text and figures with code. In this RNotebook, we will wrap up data types in vectors.

character_vector <- c("a", "b", "c")
print(character_vector)

[1] "a" "b" "c"

class(character_vector)

[1] "character"

( 
  numeric_vector <- c(1, 2, 3) 
  ) #parentheses print the variable just like the print() command

[1] 1 2 3

class(numeric_vector)

[1] "numeric"

(boolean_vector <- c(TRUE, FALSE, TRUE))

[1]  TRUE FALSE  TRUE

class(boolean_vector)

[1] "logical"

mixed_numbool <- c(boolean_vector, numeric_vector)
class(mixed_numbool)

[1] "numeric"

mixed_numbool

[1] 1 0 1 1 2 3

sum(mixed_numbool)

[1] 8

(mixed_character_anything <- c(boolean_vector, numeric_vector, character_vector))

[1] "TRUE"  "FALSE" "TRUE"  "1"     "2"     "3"     "a"     "b"    
[9] "c"    

sort(mixed_character_anything)

[1] "1"     "2"     "3"     "a"     "b"     "c"     "FALSE" "TRUE" 
[9] "TRUE" 

#in square brackets: selecting just elements that equal the digit 1 as string
str(one_number)

 chr "a"
