1. R Programming

2. Definition
• R is an open source programming language and
software environment for statistical computing
and graphics that is supported by
the R Foundation for Statistical Computing.
• The R language is widely used among statisticians
and data miners for developing statistical software
and data analysis.

3. R Reserved Words
• Reserved words in R programming are a set of
words that have special meaning and cannot be
used as an identifier (variable name, function
name etc.).
• Reserved Words in R
if else repeat while function
for in next break TRUE
FALSE NULL Inf NaN NA
NA_integer_ NA_real_
NA_complex
_
NA_characte
r_
...

4. R Variables and Constants
Variables in R
Variables are used to store data, whose value
can be changed according to our need. Unique
name given to variable (function and objects as
well) is identifier.
Constants in R
Constants, as the name suggests, are entities
whose value cannot be altered. Basic types of
constant are numeric constants and character
constants.

5. Rules for Writing Identifiers in R
Identifiers can be a combination of letters,
digits, period (.) and underscore (_).
It must start with a letter or a period. If it
starts with a period, it cannot be followed by a
digit.
Reserved words in R cannot be used as
identifiers.

6. R Operator Precedence and
Associativity
Operator Precedence
When multiple operators are used in a single
expression, we need to know the precedence of
these operators to figure out the sequence of
operation that will take place.
Operator Associativity
It is possible to have multiple operators of
same precedence in an expression. In such case the
order of execution is determined through
associativity.
