How to calculate the square root of a number in R
The sqrt() function in R is used to calculate the square root of a non-negative number.
Figure 1 shows the mathematical representation of the sqrt() function.
Syntax
sqrt(number)
Parameter
sqrt() requires a non-negative number as a parameter.
Return value
sqrt() returns the square root of the number sent as a parameter.
If a negative number is sent as a parameter, then
sqrt()returnsNaN, along with awarningmessage.
Example
#Perfect square roota <- sqrt(4);print(paste0("sqrt(4): ", a))b <- sqrt(0);print(paste0("sqrt(0): ", b))#simple numberc <- sqrt(5);print(paste0("sqrt(5): ", c))d <- sqrt(4.5);print(paste0("sqrt(4.5): ", d))#negative numbere <- sqrt(-2);print(paste0("sqrt(-2): ", e))
