sQuote() Function in R with Example

sQuote() Function in R with Example

Text in R is represented by character vectors. The text often is referred to as a string in computer programming. A character vector is a vector consisting of characters. To assign a value to a character vector, use the <- (left arrow) operator. To find the length of the character vector, use the length() function. … Read more

rnorm() Function in R: Generate Random Numbers in R

rnorm() Function in R - Generate Random Numbers in R

The rnorm() function generates a random number using a normal(bell curve) distribution. The rnorm() function simulates random variates having a specified normal distribution. What is Normal Distribution in R The normal distribution is the collection of random data from independent sources is distributed normally. We get the bell shape curve by plotting a graph with … Read more

toString() Function in R with Example

toString() Function in R with Example

The toString() function first covers its argument into a character vector and then concatenates the result’s elements if the length is greater than 1. In R, a string is a vector of characters, and all scalars are one-dimensional vectors. In R, there is no built-in string data type. Instead, it is called character, and you … Read more
