Inbuilt function in r
The functions which are already created or defined in the programming framework are known as a built-in function. R has a rich set of functions that can be used to perform almost every task for the user. These built-in functions are divided into the following categories based on their functionality. See more R provides the various mathematical functions to perform the mathematical calculation. These mathematical functions are very helpful to find absolute value, square value and much more calculations. In R, there are the … See more R provides various string functions to perform tasks. These string functions allow us to extract sub string from string, search pattern etc. There are the following string functions in R: See more Apart from the functions mentioned above, there are some other useful functions which helps for statistical purpose. There are the following functions: See more R provides various statistical probability functions to perform statistical task. These statistical functions are very helpful to find normal density, normal quantile and many more … See more WebWith the help of R, you can implement inbuilt functions that allow you to perform linear regression easily. Using common software tools, statisticians can implement various statistical tools. We will now learn how to implement a linear regression model using R.
