# R program to print
# the value of an object
# Creating a vector
x <- c(1, 2, 3, 4)
# Creating a list
list1 <- list(letters[1:6])
# Calling the identity function
identity(x)
identity(list1)
R
输出
[1] 1 2 3 4
[[1]]
[1] "a" "b" "c" "d" "e" "f"
R
例2 :
# R program to print
# the value of an object
# Calling predefined data frame
x1 <- BOD
# Creating a matrix
mat <- matrix(c(1:9), 3, 3, byrow = T)
# Calling the identity() Function
identity(x1)
identity(mat)
