R - gamma() Function
The R gamma() function returns gamma function of the argument. The gamma function of x is defined as:
Syntax
gamma(x)
Parameters
x |
Required. Specify column to compute on. |
Return Value
Returns gamma function of the argument.
Example:
The example below shows the usage of gamma() function.
#operating on single element atomic vector print(gamma(0.1)) print(gamma(0.5)) print(gamma(1.5)) cat("\nOperating on vector\n") #operating on vector v <- c(4.1, 5.1, 6.1) print(gamma(v)) cat("\nOperating on matrix\n") #operating on matrix m <- matrix(c(1.5, 2.5, 3.5, 4.5, 5.5, NaN), nrow=2) print(gamma(m)) cat("\nOperating on first column of matrix\n") #operating on first column of matrix print(gamma(m[,1]))
The output of the above code will be:
[1] 9.513508 [1] 1.772454 [1] 0.8862269 Operating on vector [1] 6.812623 27.931754 142.451944 Operating on matrix [,1] [,2] [,3] [1,] 0.8862269 3.323351 52.34278 [2,] 1.3293404 11.631728 NaN Operating on first column of matrix [1] 0.8862269 1.3293404
