用R标记法进行交叉制表

Question

我很难为一个简单好看的交叉表创建一个简单的交叉表。PDF编织的R标记 文档。我有一个数据集，和这个例子类似。

library(tidyverse)
fakeData <- tibble(id = c(1,2,3,4,5,6,7,8,9,10),
                   bmi = c("normal", "overweighted", "underweighted", "normal", "normal", "overweighted",
                           "normal", "overweighted", "underweighted","normal"),
                   gender = c("M", "F", "M", "M", "F", "F", "M", "F", "F", "F"))

我想得到一个像这样的输出。

有谁有什么诀窍，有什么好的软件包可以做到这一点？非常感谢

我想 janitor-包可以帮你解决这个问题......

注意："总计 "列中的百分比与你所期望的输出不一致......这是因为你在输出中混合了纵列和横列的百分比计算......。那是因为你在输出中混合了顺行和逆行的百分比计算。这真的是你想要的吗？

library( janitor )

fakeTable <- fakeData %>% 
  tabyl( gender, bmi ) %>% 
  adorn_totals( where = c("row", "col") ) %>%
  adorn_percentages("row") %>%
  adorn_pct_formatting() %>%
  adorn_ns( position = "front" ) %>%
  adorn_title("combined")

# gender/bmi    normal overweighted underweighted       Total
#          F 2 (33.3%)    3 (50.0%)     1 (16.7%)  6 (100.0%)
#          M 3 (75.0%)    0  (0.0%)     1 (25.0%)  4 (100.0%)
#      Total 5 (50.0%)    3 (30.0%)     2 (20.0%) 10 (100.0%)

编织

library(knitr)
library(kableExtra)
fakeTable %>%
  kable() %>%
  kable_styling(bootstrap_options = c("condensed", "striped", "bordered"))
