Correct OPTION is (c) DEFAULT status

To elaborate: The Defaultstatus is the tainted property of the WINDOW object. The defaultStatus property sets or returns the default text in the status BAR at the bottom of the browser (the text will be displayed when the page LOADS).

The correct option is (d) pmb()

The explanation: Since R RUNS on so many DIFFERENT operating systems, and supports so many different GRAPHICS formats, it’s not surprising that there are a variety of ways of saving your plots, DEPENDING on what operating system you are using, what you plan to do with the graph, and whether you’re connecting locally or remotely.

The CORRECT answer is (B) win.metafile()

For explanation I would SAY: Metafile is a piece of GRAPHICAL information stored in a format that can be exchanged between different systems or software. The method win.metafile([filename]) is used to save chart as a Window metafile.

Correct choice is (b) DISPLAYS charts

To explain I would say: The most USED plotting function in R programming is the plot() function. It is a generic function, meaning, it has MANY methods which are called according to the TYPE of object passed to plot(). The plot() function will DISPLAY a different type of chart depending on the arguments that you pass into it.

Correct answer is (B) 3

Best EXPLANATION: The replaceState() updates the most recent entry on the HISTORY stack to have the specified DATA, title, and, if provided, URL. window.history.replaceState(stateObj, title, url) : This is just like window.history.pushState, except that the current browser state is removed from the history, so you cannot HIT “back” to return to it.

Correct option is (C) S

Easy explanation: R is an implementation of the S programming language combined with lexical scoping semantics, inspired by Scheme. [15] S was created by JOHN CHAMBERS in 1976, while at Bell LABS. R and S are loosely-typed languages and it supports all of the scalar data types you WOULD expect: string, numbers, and booleans.

Right option is (b) To get the first view

Explanation: fvonly is an optional PARAMETER which is set to 1 to skip the REPEAT View test. If you set fvonly to 1, you get results only for the first view and do not run the repeat view test.

The correct choice is (B) Data FRAMES

The BEST explanation: Data frames are multidimensional lists that can contain MULTIPLE data TYPES.

Correct option is (b) Socket.CLOSE()

The explanation: The Socket.close() is used to close the WebSocket. The Close method CLOSES the REMOTE host connection and releases all managed and unmanaged resources associated with the Socket. WebSocket is a computer communications protocol, PROVIDING full-duplex communication channels over a SINGLE TCP connection.

The correct answer is (c) P

The best I can explain: Both R and S are STATISTICAL languages. The R LANGUAGE is widely USED among STATISTICIANS and data miners for developing statistical software and data ANALYSIS.

Correct CHOICE is (b) Window

The best EXPLANATION: The window object represents an OPEN window in a browser. The HISTORY object belongs to the Window object.

Correct choice is (d) Large

Explanation: R and its libraries implement a wide variety of statistical and graphical techniques, including linear and nonlinear modelling, classical statistical TESTS, time-series analysis, CLASSIFICATION, clustering, and others. As a language, R is SMALL, self-contained and extensible.

Correct CHOICE is (C) HTTP

Easiest explanation: A stateless protocol does not require the server to retain information or STATUS about each user for the duration of multiple REQUESTS. HTTP is a stateless protocol, which means that the connection between the browser and the server is lost once the TRANSACTION ends.

The CORRECT answer is (B) .R

The best I can explain: R is a programming language designed for statistical computing and graphics purposes. R is a file extension for a script written in R.

Right choice is (c) Comma separated block list

To elaborate: A ParameterBlock encapsulates all the information about sources and PARAMETERS (OBJECTS) required by a RenderableImageOp, or other classes that PROCESS images. This parameter allows you to SET a comma separated list of block options.

The correct CHOICE is (a) They get a command sequence to INSTALL the particular Linux FLAVOR

Best explanation: Instead of a compiled INSTALLER, Linux users get the command sequence to install for their particular Linux flavor.

Correct answer is (d) All of the mentioned

Easy explanation: The R language is widely used among statisticians and DATA miners for developing statistical software and data ANALYSIS. GENERALLY, R can be used to suck in data, parse it, PROCESS it, and then visualize it for reporting purposes.

Right answer is (C) symbols()

Easy explanation: symbols() function DRAWS symbols on a plot. One of six symbols; circles, squares, rectangles, stars, thermometers, and BOXPLOTS, can be plotted at a specified SET of X and y coordinates. The method symbols() is used to create a bubble chart natively in R.

The CORRECT option is (a) C()

EASIEST EXPLANATION: The c() is a GENERIC function which combines its arguments. It is used to add the vectors.

Correct option is (C) ?

The BEST explanation: The help() function and ? help operator in R provides access to the documentation pages for R functions, data sets, and other objects, both for packages in the standard R DISTRIBUTION and for contributed packages. At any time, you can TYPE ? (keyword) to open the help WINDOW for a particular subject.

The correct answer is (a) Adobe ILLUSTRATOR

To explain: Adobe Illustrator is used to produce professionally LOOKING at statistical graphics. From R, the chart is imported into the Adobe Illustrator, or any other such program, where it can CLEAN up things like font consistency and MAKE sure axis labels with long NAMES are visible.

Right choice is (a) URL

For explanation: The history OBJECT contains the URLS visited by the user. By using history object, you can load previous, forward or any particular PAGE using VARIOUS methods.

Right option is (c) barplot()

To explain: A bar chart REPRESENTS data in RECTANGULAR bars with LENGTH of the bar PROPORTIONAL to the value of the variable. R uses the function barplot() to create bar charts.

The CORRECT answer is (a) 3

To EXPLAIN: There are three methods belonging to the History OBJECT NAMELY :

back()

forward()

go()

back() loads the PREVIOUS URL, forward loads the next URL and go() loads a specific URL in the history list.

Correct option is (a) R Console

To explain I WOULD say: Interactive DATA analysis usually occurs on the R console that executes COMMANDS as you type them. R Console is a command-line environment for running ad hoc R commands.

Right choice is (d) All kinds

The explanation is: The R language is WIDELY used among statisticians and data miners for DEVELOPING statistical software and data analysis. All kinds of data can be run in R.

The correct CHOICE is (b) protocol property

Explanation: A WebSocket is a standard bidirectional TCP socket between the client and the SERVER. The socket starts out as an HTTP connection and then “UPGRADES” to a TCP socket after an HTTP handshake. Once the connection is established, the client can determine which subprotocol is in use by CHECKING the protocol property of the socket.

Right OPTION is (a) img

The best explanation: NETSCAPE is a brand name associated with the DEVELOPMENT of the Netscape web browser. The img ELEMENT can handle mouse events in Netscape.

Correct option is (a) Help window

For explanation: ? is GENERALLY used to open the help window at any time. The help() function and ? help operator in R provides access to the documentation PAGES for R FUNCTIONS, data SETS, and other objects, both for packages in the standard R distribution and for CONTRIBUTED packages.

The correct choice is (d) Both Format and Collect

The explanation: Glue language refers to a programming language that is designed SPECIFICALLY to write and manage program and code, which CONNECTS TOGETHER different software components. A glue language is GENERALLY used to collect and format the data.

The correct OPTION is (a) PUSHSTATE()

Explanation: The pushState() method adds a particular state to the browsing history. It pushes the GIVEN data onto the session history stack with the specified TITLE and, if provided, URL.

Correct OPTION is (b) Handshake connection

The explanation: The WebSocket object PROVIDES the API for creating and managing a WebSocket connection to a server, as well as for sending and receiving data on the connection. The readonly attribute readyState represents the state of the connection. It can have the following values:

A value of 0 indicates that the connection has not yet been established.

A value of 1 indicates that the connection is established and communication is possible.

A value of 2 indicates that the connection is going through the CLOSING handshake.

A value of 3 indicates that the connection has been closed or could not be opened.

Correct choice is (d) Loads the next URL in the history list

To elaborate: The FORWARD() method is found in the history OBJECT. The forward() method loads the next URL in the history list.

The correct choice is (a) Glue language

To elaborate: A glue language is generally USED to collect the data, that is written out as a comma-separated file, and read it into R. It ENABLES INTERCONNECTING, support and the integration of software programs and COMPONENTS created using different programming languages and platforms.

Correct option is (C) SOCKET.send(DATA)

To explain I would say: The Socket.send(data) method transmits data USING the connection. This Socket method sends data to CONNECTED socket.

The correct OPTION is (a) SERVER’s RESPONSE

The best explanation: The file_get_contents() is a PHP’s native function used to hit the URL and READ the server’s response into

a variable $wpt_response:

Correct ANSWER is (d) 9

For explanation I would say: Plot() is a generic function, meaning, it has many methods which are CALLED according to the type of object passed to plot(). The method plot() accepts a TOTAL of 9 parameters.
