如何在 R 中组合两个向量？
在本文中，我们将学习如何结合两个 R 编程语言中的向量。我们可以使用函数c()本身组合两个或多个向量。在使用函数c() 时，所有参数都被强制转换为一个通用类型，即返回值的类型。
Syntax: c(…)
Parameters:
- …: arguments to be combined
Returns: A vector
脚步 -
- 创建要组合的向量
- 使用 c() 组合它们
- 显示组合结果
示例 1：相同数据类型的向量将给出输入数据类型的向量作为结果。
R
a <- c(1, 2, 8)
b <- c(5, 8, 9, 10)
c <- c(a,b)
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")
a <- c("geek","for","geek")
b <- c("hello","coder")
c <- c(a,b)
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")
a <- c(TRUE, FALSE, NA)
b <- c(TRUE, FALSE)
c <- c(a,b)
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")R
a <- c(1, 2, 8)
b <- c("hello","coder")
c <- c(a,b)
# a vector of type double and b vector of type
# character result c vector of type character
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")
a <- c("geek","for","geek")
b <- c(TRUE, FALSE)
# a vector of type character and b vector of type logical
# result c vector of type character
c <- c(a,b)
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")
a <- c(1, 2, 8)
b <- c(TRUE, FALSE)
c <- c(a,b)
# a vector of type double and b vector of type
# logical result c vector of type double
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")输出：
[1] 1 2 8 5 8 9 10
typeof a double typeof b double typeof c double
[1] “geek” “for” “geek” “hello” “coder”
typeof a character typeof b character typeof c character
[1] TRUE FALSE NA TRUE FALSE
typeof a logical typeof b logical typeof c logical
组合 double 和字符类型的向量时， 字符和 logical ， double 和 logical c()函数返回字符、 字符、 double 类型的向量。
示例 2：
电阻
a <- c(1, 2, 8)
b <- c("hello","coder")
c <- c(a,b)
# a vector of type double and b vector of type
# character result c vector of type character
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")
a <- c("geek","for","geek")
b <- c(TRUE, FALSE)
# a vector of type character and b vector of type logical
# result c vector of type character
c <- c(a,b)
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")
a <- c(1, 2, 8)
b <- c(TRUE, FALSE)
c <- c(a,b)
# a vector of type double and b vector of type
# logical result c vector of type double
c
cat("typeof a", typeof(a), " typeof b", typeof(b),
"typeof c",typeof(c) , "\n")
输出：
[1] “1” “2” “8” “hello” “coder”
typeof a double typeof b character typeof c character
[1] “geek” “for” “geek” “TRUE” “FALSE”
typeof a character typeof b logical typeof c character
[1] 1 2 8 1 0
typeof a double typeof b logical typeof c double
