cbind函数在R语言中的使用

cbind(x1, x2, ...)

x <- c(1, 2, 3)
y <- c(4, 5, 6)

result <- cbind(x, y)
print(result)

     x y
[1,] 1 4
[2,] 2 5
[3,] 3 6

m1 <- matrix(1:6, nrow=2)
m2 <- matrix(7:12, nrow=2)

result <- cbind(m1, m2)
print(result)

     [,1] [,2] [,3] [,4] [,5] [,6]
[1,]    1    3    5    7    9   11
[2,]    2    4    6    8   10   12

df1 <- data.frame(name=c("Alice", "Bob", "Cathy"),
                  age=c(25, 30, 35))
df2 <- data.frame(city=c("New York", "Los Angeles", "Chicago"),
                  state=c("NY", "CA", "IL"))

result <- cbind(df1, df2)
print(result)

   name age       city state
1 Alice  25   New York    NY
2   Bob  30 Los Angeles    CA
3 Cathy  35    Chicago    IL
