如何将R输出的行矩阵更改为列矩阵

Question

我有这样的输出

[1]  1.5328880  0.7921354  2.4249702  1.1959438  6.0646937  1.8762401  0.7583533  0.4008204  2.6112780  0.9418852  0.7743362  1.2799742  0.9131632  2.5485733

我想将其转换为列格式

Answer 1

好像您有矢量

x <- 1:10
x
#[1]  1  2  3  4  5  6  7  8  9 10

将matrix与ncol = 1一起使用

matrix(x, ncol = 1)

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

或者如果您希望将其用作数据框

as.data.frame(matrix(x, ncol = 1))

---

您还可以使用双重转置将向量转换为列矩阵

t(t(x))

t(x)将其转换为单行矩阵，而t(t(x))将其转换为单列矩阵。

Answer 2

我们可以使用dim在vector中添加dim属性。 matrix是具有vector属性的dim

 dim(x) <- c(length(x), 1)

---

或使用dim<-

`dim<-`(x, c(length(x), 1))
#      [,1]
# [1,]    1
# [2,]    2
# [3,]    3
# [4,]    4
# [5,]    5
# [6,]    6
# [7,]    7
# [8,]    8
# [9,]    9
#[10,]   10

数据

x <- 1:10
