问题

问题:运行get_pi_ij()时出现错误:

Error in as.vector(x, mode) : cannot coerce type 'closure' to vector of type 'any'

Called from: as.vector(data)

这个函数的第一步是将生成的alphasbeta_prelims转换为与c匹配的矩阵,以便它们可以一起计算。这是出现问题的地方,我无法找出问题所在。如果我在前面的函数中使用<<-alphasbetas保存到全局环境中,并将它们替换为在有问题的函数中的那些,那么它就可以正常工作。因此,我认为问题可能与我在矩阵创建中调用函数的方式有关。

get_pi_ij <- function() {
  alphas <-
    matrix(get_alpha(),
           nrow = length(get_alpha()),
           ncol = length(get_alpha()),
           byrow = FALSE)
  betas <-
    matrix(get_beta_prelim(),
           nrow = length(get_beta_prelim()),
           ncol = length(get_beta_prelim()),
           byrow = TRUE) 
  pi_ij <- exp(alphas + betas + gamma * c)
  return(pi_ij)
}
get_pi_ij()

我添加了完整的代码,因为它不太长,前面的部分只是定义。这样更容易测试。

一切都正常工作,如预期那样

Problem: running `get_pi_ij()` gives the error: 

`Error in as.vector(x, mode) : cannot coerce type &#39;closure&#39; to vector of type &#39;any&#39;`

`Called from: as.vector(data)`

The first thing this function does is to make the resulting `alphas` and `beta_prelims` into matrixes that match `c` so that they can be calculated together. This is where something goes wrong, and I have not been able to figure out what. If I use `&lt;&lt;-` to save the `alphas` and `betas` to the global environment in the prior functions for alphas and betas and replace that with those in the faulty function, it works. So I assume it has to do with how I call the functions inside the matrix creation. 

    get_pi_ij &lt;- function() {
      alphas &lt;-
        matrix(get_alpha(),
               nrow = length(get_alpha()),
               ncol = length(get_alpha()),
               byrow = FALSE)
      betas &lt;-
        matrix(get_beta_prelim,
               nrow = length(get_beta_prelim()),
               ncol = length(get_beta_prelim()),
               byrow = TRUE) 
      pi_ij &lt;- exp(alphas + betas + gamma * c)
      return(pi_ij)
    }
    get_pi_ij()

I added the full code cause it&#39;s not too long and the first parts are just definitions. Makes it easier to test it.
