在 R 编程中将对象转换为向量 - as.vector()函数
R 语言中的as.vector()
函数用于将对象转换为向量。
Syntax: as.vector(x)
Parameters:
x: Object to be converted
示例 1:
# R program to convert an object to vector
# Creating an array
x <- array(c(2, 3, 4, 7, 2, 5), c(3, 2))
x
# Calling as.vector() Function
as.vector(x)
输出:
[, 1] [, 2]
[1, ] 2 7
[2, ] 3 2
[3, ] 4 5
[1] 2 3 4 7 2 5
示例 2:
# R program to convert an object to vector
# Creating a matrix
x <- matrix(c(1:9), 3, 3)
x
# Calling as.vector() Function
as.vector(x)
输出:
[, 1] [, 2] [, 3]
[1, ] 1 4 7
[2, ] 2 5 8
[3, ] 3 6 9
[1] 1 2 3 4 5 6 7 8 9
