R Cheatsheet: Vectors

A Vector is a collection of n elements of the same class.

A numeric vector:

num_vect<-c(0.5, 55, -10,6)

If we need to know which elements of the previous vector are lesser than 1:

tf<-num_vect<1

And we obtain a Logical Vector

A character vector:

my_char<-c(“my”, “name”, “is”)

Concatenate the individual elements of a vector with a ” ” (blank)

paste(my_char, collapse = ” “)

Creating a new character vector with another element

my_name<-c(my_char, “Martin”)

paste(my_name, collapse = ” “)

Using paste() function in order to concatenate each individual element of two vectors:

paste(LETTERS, 1:4, sep = “-“)
