Fundamentals of R
This topic covers some of the concepts that are unique to R like the creation of vector. The vector is an integral part of the function that accepts inputs and performs on it. The use of box brackets is widespread in R. The other programming languages use circular and flower brackets more than the other types of brackets, whereas R uses box brackets the more.
Core principles of programming
The various core principles in programming like the usage of loops, logical statements, variables, and operators are taught in this topic. This has to be understood well before one jumps into the concepts that are unique to R. The packages in R are the extension of the functions that are in use in the other languages.
Matrices in R
The matrices are an important concept in Statistics. The data in statistics are obtained in the form of rows and columns only as they are the values of the different parameters that are obtained as a part of conducting surveys or the historical data like the histogram. The matrices can have any number of rows and columns.
The limited number of rows and columns can be operated by manual calculations. A little bigger number in the number of rows and columns can be calculated using the scientific calculator. Still, the time consumed was large only. Thus, the R has this specialized operator functions on Matrices that performs operations quick.
There are some functions in R that helps even to name the dimensions of the matrix. The rows can be given a name and the columns as well. The answer that has been obtained can be visualized using plots. The plotting is another good feature in R.
Data Frames in R
When Speaking of Data Sciences and Data Analytics using R, this concept comes into action. So far, one has read about the functions and the packages in R that complement the statistical calculation of data. The concept of Data Frames explains how R plays a vital role in Data Sciences and Data Analytics.
The Data Frames are used to import the data that has been in any forms of extension files. The $ sign is the main aspect of the functions of Data Frames. The data thus obtained as input is scattered and it is not in a state that can be analyzed.
One has to perform operations like filtering, sorting, etc., the vector function is used to obtain the input. There are functions like trim to perform operations to provide neat data that can be plotted. The merging of data is also possible.
Visualization using GGPlot2
The GGPlot2 is an advanced visualizing tool that is used in R language. The GGPlot2 is used to transform statistical data using some advanced and new concepts like Facets, Co-ordinates, Layer Plotting, etc., this kind of visualization is used these days to provide the movie ratings.
A mass survey or polling that is conducted will have data inputs in the form of a histogram and other graphical representations. The values that are obtained in the form of graphs are mapped and transformed that they can be plotted and visualized. The GGPlot2 is an advanced tool that provides excellent visualization.
Solutions to Homework

R and Statistics
Statistics is one of the oldest forms of sciences. The statistics have gained a lot of momentum, especially after the globalization and liberalization era. The quantity and the variety of jobs have increased. The number of job seekers has increased. The different types of jobs have come into the market. When there is a huge, sudden influx of jobs, there arises a need to create a database to store all the data to analyze the current situation and to predict the prospects.
The Statistical analysis department of every firm, every country is infested with the task of working on statistical data and derive useful insights out of it. This was done manually earlier usually calculators to perform calculations. Later came in the use of technology, the Data Base Management Systems, Spreadsheets came into action. When the data size grew, the manual calculations and the simple tech tools were no longer able to manage the data and provide accurate results. This gave the need for the development of languages like R.
Now, in this century where state data is ruling the world, R comes to the rescue.
Methods by which R solves Statistical problems:
There are many inbuilt functions in the R packages. The R package has the functions that can be used to solve the statistical problems.
