R 矩陣的分位數 - 錯誤 output

Question

我可能在這里犯了一些簡單的錯誤，但我有一個矩陣，我想產生整個矩陣的分位數。 我試過這個：

quantile(unlist(ricepm), probs = c(.25, .5, .75))

但這給了我錯誤的 output（全為 1）

25% 50% 75% 
  1   1   1 

我的數據的dput(head(ricepm[, c(5, 5)]))樣本

structure(
    list(
        Antigua.and.Barbuda = 
            structure(c(1L, 1L, 1L, 1L, 1L, 24L), 
                .Label =

如果您只想將矩陣Z的所有值放入向量中並從中獲取分位數，您可以執行以下操作：

# Put values inside vector
Z_vec = as.vector(Z)

# Compute quantiles
 quantile(Z_vec, probs = c(.25, .5, .75))
