What Is R Programming?

R programming language is an open-source programming language that is used to create the best software environment to do statistical computing and prepare graphics. This statistical language is used by statisticians, data analysts, and data miners to mine data and does statistical data analysis. The popularity of this language can be seen when the researchers are conducting polls, surveys, and other literary works. 

The excellent part of R Programming is that it saves time and helps deliver accurate results. This is also efficient in handling data and storage facilities. R Programming language is compatible to use with C, C++, Java, FORTRAN, and .Net. This interpreted language would not need any kind of compiler to write a program from the code that is already used before. R Programming is available with General Public License. It can run on almost all operating systems including Linux, UNIX, Windows, Mac, and others operating systems. The best thing is that it allows integration with other statistical software like SAS and SPSS. This plays a critical role in carrying out clinical trials, research works, and medicine.

Matrices: Matrices are the R objects in which the elements are arranged in a two-dimensional rectangular layout. It has many data types. We will produce matrices with characters or logical values that are not used widely. 

Vectors and lists: Vectors are homogenous data structures with elements of similar data types like integer, character, logical, and numeric. There are heterogeneous data structures that have mixed types of data. 

Data Frames: A data frame is a kind of table or two-dimensional array structure that has columns with 1 variable value and rows that have values from each of the columns. 

Factors: Factors are the data structures in R that would express the significance of each level and are relevant for arranging variables categorically. 

R packages: The package that is R will have various library functions such as select (), filter (), arrange (), and summarize (). Some of the packages of R include Dplyr, superml, tree, MASS, ggplot2, and so on. 

ML Algorithms in R Programming

There are six different types of machine learning algorithms that are widely used in the R programming language:

Linear Regression

Im () package that in linear regression model would be widely used for training the data in R programming. It also offers a linear relationship between x, y, and various features.

Logistic regression

Glm () is a kind of stats package that is used for training the logistic regression in R. It has a linear decision boundary that would help you to classify various data points.

Naive Bayes

Naive_bayes () is a package that is available under naive Bayes that is widely used for training the Naive Bayes model available in R. It is a kind of algorithm that is based completely on the Prior as well as Posterior probabilities. 

SVM

SVM () is a package that is available under the e1071 package which allows you to train the support vector machine model in R. Regression as well as classification will be used for estimating the density. 

Decision tree

Tree () is available in trees package that is used to train the decision tree available in R. Similar to SVM, both regression and classification would be done through binary recursive partitioning. 

KNN

kNN () is a DMwR package used to train the k-nearest neighbor model in R. Data normalization can also be done prior to using the training model to train the data. 

Clustering

Kmeans () is the stats package that would let you do k-means clustering on the data matrix that is available in R. This is the unsupervised algorithm that lets you segment and group the data that is labeled.
