Question

我是R的面向对象设置的新手，所以轻松一点：）

我正在使用msm library，尤其是pmatrix function。此函数正确运行并在调用时打印矩阵：

t = pmatrix.msm(x=fb.msm.tech)。

print(t)

            State 1      State 2   State 3    State 4    State 5
State 1 0.215414273 0.0177223229 0.6120709 0.08127077 0.07352177
State 2 0.033494683 0.6421517256 0.2223060 0.02454739 0.07750024
State 3 0.007500551 0.0001843707 0.7530770 0.15781630 0.08142178
State 4 0.008522211 0.0002170102 0.2993561 0.57798320 0.11392148
State 5 0.000000000 0.0000000000 0.0000000 0.00000000 1.00000000

t是类msm.est的对象，但我想将其转换为data.frame（或矩阵）。我该怎么做？这会导致错误：

> data.frame(t)
Error in as.data.frame.default(x[[i]], optional = TRUE) : 
  cannot coerce class ‘"msm.est"’ to a data.frame

以下是有关t的一些属性；让我知道您是否需要更多信息：

> typeof(t)
[1] "double"

> str(t)
Error in unclass(x)[i, j] : subscript out of bounds

> class(t)
[1] "msm.est"

> methods(class=class(t))
[1] [     print
see '?methods' for accessing help and source code

Answer 1

msm.est对象基本上只是具有特殊类的矩阵。您可以删除该类以获得矩阵，然后使用data.frame()将矩阵转换为data.frame。

data.frame(unclass(t))

R-“无法将类别“” msm.est“”强制转换为data.frame“
