表 1 r function

Question

I'm using the r function table1() to get descriptive statistics by group

table1(~ factor(sex) + age + factor(ulcer) + thickness | status, data=melanoma2)

see example here

for categorical variables, I want the percentage with two digits after the decimal: x.xx% and add for continuous variables the N,Q1,Q3 Is that possible?

Thanks in advance!

Answer 1

This is the answer for question 2: "How to add for continuous variables the N,Q1,Q3 Is that possible?"

You could add render.continuous.. to your code:

table1(~ factor(sex) + age + factor(ulcer) + thickness | status, 
       data=melanoma2, render.continuous=c(.="N", .="Q1", .="Q3",.="Mean", .="SD", .="Median [Min, Max]"))
