The bar chart in R uses rectangular bars to visualize the data. The height of the bars is proportional to the values they represent. The bar charts can be displayed either horizontally or vertically. By using the barplot() function a vertical bar chart is drawn: Output The above example shows: The x variable represents values in the … Read more
The R function is a set of statements that are organized together to perform a particular task. R language facilitates a series of built-in functions and permits to use to create their own functions. The modular approach is used to perform tasks in functions. Usually, functions are used to avoid repetition of the same task … Read more
The R classification algorithm is a very easy task. By analyzing the training dataset we can predict the target class. We can obtain better boundary conditions that can be used to check the target class using the training dataset. The whole process is known as classification. R Classification algorithms Some important points of R classification … Read more
The list in R contains several unique data types inside it. A collection of data that is ordered and editable is called a list in R. We used the list() function to create a list: Output Access List in R To access the list items, refer to its index number inside brackets. The first item has index … Read more
The time series in R is a series of data points in which each data point is linked with a timestamp. The best example of time series in R is the price of a stock in the stock market at different points of time on a given day. The amount of rainfall in a region … Read more
The rectangular dataset in two dimensions is called a matrix in R programming. A matrix is created with a vector input to the matrix function. Mathematical operations can be performed like add, subtract, multiply, and division on a matrix in R programming. Elements are arranged in a fixed number of rows and columns in the … Read more
The variable in the R language has a data type. All data types in R programming need some memory and have some operations that can be performed over it. We have the following data types in R programming: 1. Numeric data type in R The decimal values in the R language are called numeric. It … Read more
Arrays in R can have more than two dimensions as compared to the matrix. Arrays in R, are created using the array() function. The array() function takes the vector as input and used its values in dim parameters to create an array. Suppose, we create an array of (2, 3, 4) dimensions, it will create … Read more
we can read and write a binary file in R. A file that contains information present only in the form of bits and bytes (0 and 1) is called a binary file. A binary file is not readable by humans. The data generated by the other programs need to be processed by R as a … Read more
The R factor is a data structure that is used for the purpose of the field which takes only a predefined finite number of values. R factors take a limited number of different values. To store data on multiple levels and categorize the data is done by these objects. Strings and integers can be stored … Read more
