Base functions are a set of functions in the R programming language that are included in the base package, which is automatically installed and loaded when the R problem executes. These functions provide a wide range of functionality, including mathematical operations, statistical functions, data manipulation, and input/output operations.
In this article, I will explain some R base functions from the R Programming Language.
R Mathematical Functions
R Base Package has a wide range of built-in mathematical functions that can be used to perform various types of mathematical operations, such as arithmetic, algebraic, trigonometric, and statistical functions.
The R Arithmetic operations are
%% and below are some algebraic functions.
|R Mathematical Functions||Description|
|abs()||Calculate the absolute value of a numeric vector.|
|sqrt()||Calculate the square root of a numeric vector.|
|round()||Calculate the round of a numeric vector.|
|ceiling()||Round numbers up to the nearest integer.|
|floor()||Round numeric values to the nearest integer.|
|sign()||Returns -1 for negative values, |
Returns 1 for positive values,
And 0 for zero.
|exp()||Calculate the exponential value of a numeric vector.|
|log(), log10()||Calculate the natural logarithm of a numeric vector.|
These are just a few examples, and there are many more mathematical functions available in R. You can find a complete list of mathematical functions in the R documentation or by typing
help(math) in the R console.
R Statistical functions
R also has a wide range of built-in statistical functions that can be used to perform various types of statistical analyses, such as computing descriptive statistics, testing hypotheses, and fitting statistical models.
Besides R base functions, you can also use specialized packages in R, such as the
stats package, to access additional statistical functions.
Here are some examples of common statistical functions in R.

help(stats) in the R console.
R Input / Output Functions
|R Input/Output Functions||Description|
|print(), sprintf(), print()|
In this article, you have learned different R base package functions. Functions from the R base package are automatically installed and available to use by default. These functions provide a wide range of functionality, including mathematical operations, statistical functions, data manipulation, and input/output operation
