About
R Data Science
Python is one of the most leveraged high-level programming languages with several capabilities. Owing to the increase in data accumulated and demand in analytics, Python has been considered one of the Data Science is most sought-after factors in the present-day scenario. In the wake of the increasing amount of data accumulated every day, one requires a sophisticated methodology – Data Science - to arrive at sane results from insanely humongous data. Data Science can be applied to data using any one of the tools available, which includes R Programming.
R Programming is one of the most widely used analytics tools for performing Data Analysis apart from SAS and Python. R has vast capabilities and has rich statistical and reporting functionalities. Like other programming languages, R Programming has its own set of syntaxes, variables, and tool-specific capabilities, which will be covered in training.

6. Built-in Functions
In this section, we will be discussing several Built-in Functions in R Programming, such as Sum, Min, Max, Count, Average, Sequence, Repetition, Range, etc.
7. User-defined Functions
This section will discuss how to write user-defined functions, functions with parameters, parts with default values, call functions by position and name, lazy evaluation, etc.
8. Vector, Lists, Matrices
This section will discuss the creation of vectors, lists, and matrices. Furthermore, we will be deep diving into these concepts, such as sub-setting using index position or names and performing arithmetic operations.
9. Data Frames
In this section, we will be discussing data frames in detail. We will be covering topics such as data frame creation, structuring data frames, a summary of data frames, how to apply functions, filters, aggregation, joins, and many more.
10. Regular Expressions
In this section, we will be discussing what a regular expression, available regular expression patterns are, and apply regular expression patterns using built-in functions, such as Grep, Grepl, Regexpr, Gregexpr, Regexec.
11. Data
In this section, we will discuss how to read and write CSV files, Excel Files, JSON files, text files, databases, Rest API, XML files, SAS, SPSS, STATA Data Sets, and Web Scrapping.
12. R Packages
This section will discuss what R Packages are, various available R Packages such as SQLDF, PLYR, DPLYR, Data Tables, and how to install R packages.
13. Charts and Graphs
In this section, we will be discussing how to produce Bar Charts, Pie Charts, Boxplots, Histograms, Line Graphs, Scatterplots, Google Visualization, and ggPlot2.
14. R Statistics
In this section, we will be discussing various statistical functions such as mean, median, mode, regression, distribution, etc.
15. Introduction to Data Science
In this section, candidates will be taught what data science is, how to get insights from the data, understand machine learning, how it works, and the role of a data scientist. Ideally, candidates will be getting a big picture about data science, machine learning and how to apply the machine learning concepts in data sets.
16. Data Pre-processing
Before applying Machine Learning algorithms to a data set, it is mandatory to perform data cleansing, including fixing missing values, outliers, categorical data manipulation, and feature scaling. Furthermore, candidates will acquire knowledge and know-how in splitting data into train and tests.
17. Regression
In this section, candidates will learn what regression, when and where the regression algorithms can be applied is, and various regression algorithms such as simple linear regression, multiple regression, support vector regression, polynomial regression, random forest and decision tree. Candidates will learn how to choose predictor and dependent variables and know how to create a machine learning model on a data set. Furthermore, candidates will learn to evaluate machine learning models using machine learning error metrics.
18. Classification
In this section, candidates will learn what classification is, when and where the classification algorithms can be applied, various classification algorithms such as logistic regression, support vector machine classification, Naïve Bayes classification, and K-Nearest Neighbours (K-NN) algorithm, random forest and decision tree. Candidates will learn how to choose predictor and dependent variables and know how to create a machine learning model on a data set. Furthermore, candidates will learn to evaluate machine learning models using machine learning error metrics.
19. Clustering
In this section, candidates will learn what clustering, when and where the clustering algorithms can be applied is, and various clustering algorithms such as K-means Clustering and Hierarchical Clustering. Candidates will learn how to choose cluster size. Furthermore, candidates will learn to evaluate machine learning models using machine learning error metrics.
20. Associative Rule Learning
In this section, candidates will learn how to build a market basket machine learning model. Furthermore, candidates will learn to evaluate machine learning models using machine learning error metrics.
21. Reinforcement Learning
This section will teach candidates how to build a machine learning model for scenarios with minimal data sets.
22. Natural Language Processing
In this section, candidates will learn to gather features from the text files and create a sentiment analysis model.
23. Dimensionality Reduction
In this section, candidates will learn to choose how to choose a suitable feature (variable) while building a machine learning model.
24. Model Selection
This section will teach candidates how to evaluate machine learning models using machine learning error metrics such as K-fold cross-validation and Grid Search techniques.
25. Project
Once they complete the course, candidates will be provided with a project that they must complete applying the knowledge gathered during the training.
