这是我的数据框：

df <- structure(list(Species = c("AUS", "AUS", "AUS", "AUS", "AUS", 
"AUS", "AUS", "AUS", "AUS", "AUS", "AUS", "AUS", "AUS", "AUS",

)), .Names = c("Species", "Specimen", "Tooth", "cod"), row.names = c(NA, 
80L), class = "data.frame")

我如何获得这样的表： enter image description here

我希望首先按物种重新排序，然后按牙齿分组，计算每个物种/牙齿有多少颗牙齿，列出标本（用逗号分隔），以及列出代码（鳕鱼）。

kableExtra-0.9.0需要valign="top"； -0.8.0尚未进行垂直对齐。

library(dplyr)
library(knitr)
library(kableExtra)

group_by(df, Species, Tooth) %>%
  summarize(
    n=n(),
    Specimen=paste(Specimen, collapse=", "),
    cod=paste(cod, collapse=", ")
  ) %>%
  kable(format="html", align="c") %>%
  kable_styling(full_width = FALSE) %>%
  column_spec(1, bold = TRUE) %>%
  collapse_rows(columns = 1, valign = "top")
