  1. What is data import in R language?

In the console the user will type the Rcmdr which is the command of the R commander GUI. The data can be imported in three ways, enter the name of the data set in the dialog box then select the dataset in the dialogue box, the editor of the R commander is used to enter the data and it is used in case of large data, plain text file (ASCII) are used to import the data from the URL, from the statistical package or from the clipboard.

  1. What are the ways to communicate the outputs of the data analysis in R language?

To do the research Knitr single document is used, it combines the data, code and analysis, it helps to check the findings and turn them in to conversations.

R Programming Training is conducted with industry experts and holistic environment to enhance the learning attitude of the students.

  1. List out the difference between library() and require() functions in R language?

If the package is not loaded then the library () function gives an error message and whether it is already loaded or not it loads the packages. Whenever a particular package is not found then require () function shows a warning message. It checks the previous loads and loads the function if it is not loaded. Both the types of function will not reload a package which is already loaded and this is designed to avoid the errors.

  • Analyst managers
  • Business analyst
  • R data scientist

As of now, R Programming has an encouraging future in the competitive world.

It is considered to be widely used by leading corporates such as Airbnb, Google and many other for the analysis of data by the data scientists. Its deployment can be witnessed in the field of statistical computing, scientific research along with data analytics.

R programming is well-known language that is made used by marketers and researchers for the cleaning, visualizing, retrieving along with the analysis of the data. Its popularity is due to the strong syntax along with simple interface. Robert Gentleman and Ross Ihaka formulated this language who's first letter is kept as the language's name.

Overview of R

This language enables the usage of functions along with looping and branching. The procedure for integration happens that are written .Net, C, Python or Fortran languages. It is possible to operate over Windows, Linux and Mac.

Progression of R

As every other programming language prevailing around the world, R programming has also undergone numerous changes. It came into existence in the year 1993 and during the mid of 1997 a team called "R Core Team" modified the source code of R language.

Characteristics of R

  • As this language consists of conditionals, user defined functions, loops, it is considered to be complex free.
  • It is good at both storage and data handling.
  • For making the process of data analysis filled with graphical facilities along with presenting it over computer or even on papers.
  • This language is best in performing operation such as arrays, vector and also matrices.

Data Types

There are variety of data types present in the R language such as wide character, double floating point, integer, Boolean, floating point and many other. In general, it is very crucial to store data for its usage in future. In other words, it is necessary to free up some space when any variable is created.

For every process, operating system assigns memory as per the data type used. When R programming is compared with other languages such as Java and C, there is presence of declared variables in other programming languages.  The most commonly used R-objects are:

  • Matrices
  • Factors
  • Vectors
  • Arrays
  • Lists
  • Data frames


This is deployed for providing the user with storage in which programs can be manipulated. It is able to store the atomic vector, combination of Robjects along with group of atomic vectors. A proper variable includes letters, underline characters, dot or number.


It is considered to be compiler in order to accomplish certain logical as well as mathematical manipulations.

Types of operators

We have the following types of operators in R programming −

  • Miscellaneous Operators- %in%, %*%
  • Logical Operators- &, |, !
  • Assignment Operators- <−, <<−
  • Arithmetic Operators- +,-, *, /, %%, %/%, ^
  • Relational Operators- >, <, ==, <=, >=, !=

R-Decision making

In this the programmer's instruction play a vital role for both evaluation and testing of them. This happens with any statement that is executed in any program.

R- Loops

At times, it is necessary to run several code for many times. In such case, the execution of statements happen in an orderly manner where execution of first statement is given priority.


It is considered to be nothing more than set of statements that are arranged together in order to perform any particular task.  In this, function acts as an object in the interpretation in order to control the function.

Function components

The components of a function consist of:

Arguments- This is considered to be the placeholder. Arguments are optional and this may have no arguments present in it.

Return value- It acts as last expression for the evaluation.

Function name- This is the real name of function.

Function body- It includes cluster of statements, which defines the action of the function.


In R programming the value written under single or double quotes acts as string. Even though the user creates it with single quote, in R programming every string is stored in double quotes.


Vector is considered to be the basic data objects which are categorized into six- integer, character, double, logical, raw, and complex.


This consist of various elements such as string, number and vector within it.


These are the objects that arrange elements into 2-D rectangular layout. Matrices that consist of numeric elements are used in order to perform mathematical calculations.


They are deployed for the storage of more than 2-D objects.


This data object is deployed for the categorization of data along with its storage that can be either integer or string.

R-Data frames

This is 2-D array  that consist of one variable along with set of values.

Below are the features of a data frame.

  • names of the row must be unique.
  • data stored in data frame may be numeric,  factor or character type.
  • column names should not be empty.
  • Every column must have same count of data items.


It is a set of functions, sampled data along with compiled data that are stored in a directory. It is possible to add on more packages when necessary in the future.

R-data reshaping

It is the way of changing the organization of data within column and row. The process is accomplished by fetching the information as data frame. R programming includes various split functions along with merging and interchanging of rows and columns in any data frame.

R-CSV files

It is possible to gather information from the files that are stored outside R environment along with writing of data into files such as csv, xml and many more that can be stocked along with accessing by operating system. R programming will be able to read the files that are under the directory that the user is currently working into.


This spreadsheet is widely in usage by many of the user's that helps in storing various files such as .xlsx and even .xls format.

With the help of R the user is able to write anything into the excel file.
