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 = «-«)
