We learned how to create vectors and how many types of vectors there are. In this tutorial, we learned about R vectors. We can classify them as one-dimensional, homogeneous data structures.ĭon’t know much about inbuilt data structures in R? Then have a look at basic data structures in Rwith examples. They are sequences of values of the same data type. Vectors are one of the basic data structures of R.

tell whether the vector is of the corresponding type or not. The functions is.numeric() /is.character() /is.logical() etc. Type checking and conversion functions – the functions as.numeric() / as.character() / as.logical() / as.integer() can convert a vector into their corresponding type. sum() – The sum() function returns an integer value which is the sum of all the elements in a vector.Ĥ. The function repeats until it reaches the length.ģ. length.out: the length of the resultant vector.each: number of repetitions for each element of the vector.X: x is the numeric vector that is repeated.The function has the following arguments: rep() – The rep() function repeats a given numeric vector. along.with: the length of this argument can define the length of the sequence.Ģ.seq()– seq() function generates regular numeric sequences. Here are some of the commonly used functions:ġ.

R has many functions that can manipulate vectors or get more information about them. Therefore, the first vector is cycled twice to match the second. Note: Here, the first vector vec has five elements. If the two vectors are of unequal length, the shorter one will be recycled to match the longer vector. Subtraction of vector > vector_sub vector_subĭivision of vector > vector_div vector_div Multiplication of vector > vector_mul vector_mul For example:Īddition of vectors > vector_add vector_add This adds the corresponding members in the two vectors. We can also perform an arithmetic operation like an addition of two vectors of equal length. For example:Īddition: > vec_plus_three vec_plus_three This means that the operations are performed on each member. R performs arithmetic operations on vectors memberwise. What are some basic vector arithmetic in R? Character vector indexing is useful when dealing with named R vectors. We use a character vector, only to index vectors with a ‘names’ attribute. When using negative integral vectors, R removes the denoted elements and returns the remaining as the result. In negative integral indexing, negative integers denote the elements to be excluded. We can also use vectors of positive integers to include multiple specific elements while leaving others. We can use positive integers to select specific elements. This includes the elements which satisfy the condition while removes those who don’t. Instead of using logical vectors of equal length, we can also use a logical condition. R includes the elements corresponding to TRUE in the index vector and omits the elements corresponding to FALSE. We can use a vector of logical values to index another vector of the same length. Let us look at these different indexing techniques: 1. We can select or omit elements of a vector, by appending an index vector in square brackets to the name of the vector. We use vector indexing to access the elements of a vector. The conversion takes place from lower to higher types. If there is more than one data type, the c() function converts the elements. Vectors only hold elements of the same data type.

The c() function can also combine two or more vectors and add elements to vectors. Their type is double while their class is numeric. The numeric class stores values as double-precision floating-point numbers. This is because of the way numeric-class stores a value. Note: The typeof() function returns “double” for numeric values. We can use the typeof() function to find the type of a vector. Character VectorsĬode: > char_vec char_vec 5. Vectors containing logical values of TRUE or FALSE.Ĭode: > log_vec log_vec 4. Integer VectorsĬode: > int_vec int_vec 3. Numeric VectorsĬode: > num_vec num_vec 2. To create a vector, we use the c() function:Īnother way to create a vector is the assign() function.Ĭode: > assign('vec2',c(6,7,8,9,10)) #creates a vector named vec2Īn easy way to make integer vectors is to use the : operator.Ī vector can be of different types depending on the elements it contains. There are numerous ways to create an R vector: 1. Keeping you updated with latest technology trends, Join TechVidvan on Telegram How to create vector in R?
