可以通过计数之后再除以总数，从中得到频率 我的回答可能不切 如果还需要交流，可以贴出具体函数，祝好

set.seed(2021)
x =  round(rnorm(100, 100, 2))
tx = table(x)
ptx = prop.table(tx)
ptx100 = ptx * 100
# ptx100 = formattable::percent(ptx)
cbind(tx,ptx,ptx100)
# data.frame(tx,ptx,ptx100)

data(mtcars)
factor(mtcars$cyl) # factor in R
table(mtcars$cyl) # table in r
plyr::count(mtcars, 'cyl') # dplyr frequency table
epiDisplay::tab1(mtcars$cyl,sort.group="decreasing",cum.percent=T)

prop.table()就可以啦
