What is factor in R?
Factors are vectors with labels. This is different than character vectors or even numeric ones because they’re what R folks call “self describing”, allowing R’s functions to automatically make more sense of them than they would of the other types. They’re built with the factor function which needs to be fed a vector as an argument:

What is the main implementation of R?
The main R implementation is written in R, C, and Fortran, and there are several other implementations aimed at improving speed or increasing extensibility. A closely related implementation is pqR (pretty quick R) by Radford M. Neal with improved memory management and support for automatic multithreading. Renjin and FastR are Java implementations of R for use in a Java Virtual Machine. CXXR, rho, and Riposte are implementations of R in C++. Renjin, Riposte, and pqR attempt to improve performance by using multiple processor cores and some form of deferred evaluation. Most of these alternative implementations are experimental and incomplete, with relatively few users, compared to the main implementation maintained by the R Development Core Team.
What are the capabilities of R?
The capabilities of R are extended through user-created packages, which allow specialised statistical techniques, graphical devices, import/export capabilities, reporting tools ( RMarkdown, knitr, Sweave ), etc. The large number of packages available for R, and the ease of installing and using them, has been cited as a major factor in driving the widespread adoption of the language in data science. The R packaging system is also used by researchers to create compendia to organise research data, code and report files in a systematic way for sharing and public archiving.
What is a scalar in R?
Instead, a scalar is represented as a vector with length one. Many features of R derive from Scheme. R uses S-expressions to represent both data and code. Functions are first-class and can be manipulated in the same way as data objects, facilitating meta-programming, and allow multiple dispatch.

What is computation in R?
Computation in R consists of sequentially evaluatingstatements. Statements, such asx<-1:10ormean(y), can be separated by either a semi-colon or a new line. Whenever the evaluatoris presented with a syntactically complete statement that statement is evaluated and thevaluereturned. The result of evaluating a statement can be referred to as the value of the statement1The value can always be assigned to a symbol.Both semicolons and new lines can be used to separate statements. A semicolon alwaysindicates the end of a statement while a new linemayindicate the end of a statement. If thecurrent statement is not syntactically complete new lines are simply ignored by the evaluator.If the session is interactive the prompt changes from ‘>’ to ‘+’.
What is dimattribute in R?
Thedimattribute is used to implement arrays. The content of the array is stored in a vectorin column-major order and the dimattribute is a vector of integers specifying the respectiveextents of the array. R ensures that the length of the vector is the product of the lengths of thedimensions. The length of one or more dimensions may be zero.
What are the components of a function in R?
In R functions are objects and can be manipulated in much the same way as any other object.Functions (or more precisely, function closures) have three basic components: a formal argumentlist, a body and an environment. The argument list is a comma-separated list of arguments.An argument can be a symbol, or a ‘symbol=default’ construct, or the special argument....The second form of argument is used to specify a default value for an argument. This valuewill be used if the function is called without any value specified for that argument. The...argument is special and can contain any number of arguments. It is generally used if the numberof arguments is unknown or in cases where the arguments will be passed on to another function.The body is a parsed R statement. It is usually a collection of statements in braces but itcan be a single statement, a symbol or even a constant.
What are the three types of objects in R?
There are three types of objects that constitute the R language. They arecalls,expressions,andnames. Since R has objects of type"expression"we will try to avoid the use of the wordexpression in other contexts. In particular syntactically correct expressions will be referred toasstatements.
Is R good for data analysis?
While R can be very useful as a data analysis tool most users very quickly find themselveswanting to write their own functions. This is one of the real advantages of R. Users can programit and they can, if they want to, change the system level functions to functions that they findmore appropriate.

R is an open-source implementation of the S programming language combined with lexical scoping semantics from Scheme, which allow objects to be defined in predetermined blocks rather than the entirety of the code. S was created by Rick Becker, John Chambers, Doug Dunn, Jean McRae, and Judy Schilling at Bell Labs around 1976. Designed for statistical analysis, the language is an interpreted language whose code could be directly run without a compiler. Many programs writte…
Implementations
R's data structures include vectors, arrays, lists, and data frames. Vectors are ordered collections of values and can be mapped to arrays of one or more dimensions in a column major order. That is, given an ordered collection of dimensions, one fills in values along the first dimension first, then fill in one-dimensional arrays across the second dimension, and so on. R supports array arithmetics and in this regard is like languages such as APL and MATLAB. The special case of a…

Various applications can be used to edit or run R code.
Early developers preferred to run R via the command line console, succeeded by those who prefer an IDE. IDEs for R include (in alphabetical order) Rattle GUI, R Commander, RKWard, RStudio, and Tinn-R. R is also supported in multi-purpose IDEs such as Eclipse via the StatET plugin, and Visual Studio via the R Tools for Visual Studio. Of these, RStudio is the most commonly used.
