在R中使用table1使用缩写代码指定自定义渲染器

Question

Hello I don't have many experience with R but I need help using abbreviated code to specify a custom renderer for the "table1" package in R. I would like to not display the default stats(FREQ,PCT) variable for categorical data and only display the frequency and omit the percent. The code in R Documentations show how to customize this for continuous variables and show some custom statistics for different variables.

This is just for the convenience of displaying a frequency table with the built html formatting of package 1. I do know how to get this information otherwise. I am interested learning how to use more this package in R.

rndr <- function(x, name, ...)
  {(what <- switch(name,
        c_race = "FREQ",
    parse.abbrev.render.code(c("", what))(x))
}


table1::table1(~c_race|c_ethnicity*c_gender, data = childlearn_demo, 
   render=rndr, overall="Total",topclass="Rtable1-zebra")

Answer 1

The purpose of "abbreviated code" is to allow flexibility without needing to write your own function. Thus, you can get the desired result by simply using render.categorical="Freq" , ie:

table1::table1(~ c_race|c_ethnicity*c_gender, data = childlearn_demo,
   overall="Total",topclass="Rtable1-zebra", render.categorical="Freq")

(note: I am the table1 package author)
