(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – Arrays Arrays are the R data objects which can store data in more than two dimensions. For example − If we create an array of dimension (2, 3, 4) then it creates 4 rectangular matrices each with 2 rows and 3 columns. Arrays can …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – Matrices Matrices are the R objects in which the elements are arranged in a two-dimensional rectangular layout. They contain elements of the same atomic types. Though we can create a matrix containing only characters or only logical values, they are not of much use. …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – Lists Lists are the R objects which contain elements of different types like − numbers, strings, vectors and another list inside it. A list can also contain a matrix or a function as its elements. List is created using list() function. Creating a List Following is …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – Vectors Vectors are the most basic R data objects and there are six types of atomic vectors. They are logical, integer, double, complex, character and raw. Vector Creation Single Element Vector Even when you write just one value in R, it becomes a vector …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – Strings Any value written within a pair of single quote or double quotes in R is treated as a string. Internally R stores every string within double quotes, even when you create them with single quote. Rules Applied in String Construction The quotes at …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – Functions A function is a set of statements organized together to perform a specific task. R has a large number of in-built functions and the user can create their own functions. In R, a function is an object so the R interpreter is able …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – Next Statement The next statement in R programming language is useful when we want to skip the current iteration of a loop without terminating it. On encountering next, the R parser skips further evaluation and starts next iteration of the loop. Syntax The basic syntax for …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – If Statement The break statement in R programming language has the following two usages − When the break statement is encountered inside a loop, the loop is immediately terminated and program control resumes at the next statement following the loop. It can be used …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – For Loop A For loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times. Syntax The basic syntax for creating a for loop statement in R is − for (value in vector) { statements } …
(R Tutorials for Citizen Data Scientist) Beginners tutorial with R – While Loop The While loop executes the same code again and again until a stop condition is met. Syntax The basic syntax for creating a while loop in R is − while (test_expression) { statement } Flow Diagram Here key point of the while loop is …
