Calculate Square root of a number in R Language - sqrt() Function Last Updated : 28 Nov, 2023 Comments Improve Suggest changes Like Article Like Report Square Root of a number is the value that yields the original number when multiplied by itself. If "x" is a number, its square root is written in mathematical notation as √x. we can calculate the square root in R using the sqrt() function. In the R Programming Language, we have an inbuilt function known as the sqrt() Function to calculate the square root in R. sqrt() function in RTo find a number's square root in R, use the sqrt() function. The integer you wish to find the square root of is the only argument required.The function yields the supplied number's positive square root.Syntax: sqrt(x) Parameter: x: Any numerical value greater than 0 Calculate Square root using sqrt() Function R # R code to calculate square root of a number x1 <- 16 x2 <- 18 # Using sqrt() Function sqrt(x1) sqrt(x2) Output: [1] 4[1] 4.242641Calculate Square root of a decimal number using sqrt() Function R # R code to calculate square root of a number x1 <- 8.34526 x2 <- -18 # Using sqrt() Function sqrt(x1) sqrt(x2) Output: [1] 2.888816[1] NaNWarning message:In sqrt(x2) : NaNs produced Here, in the above code, NaN is produced because we passed a negative value in the sqrt() function. Calculate Square Roots of Multiple Numbers in a Vector R # Calculate square roots of multiple numbers in a vector numbers <- c(9, 25, 49, 64) results <- sqrt(numbers) print(results) Output: [1] 3 5 7 8we calculate the square roots of multiple numbers stored in a vector. The sqrt() function is applied to each element in the vector, and the results are stored in another vector called results.
