table1 {tableeasy}

Table 1

Description

Create an object summarizing all baseline variables ( both continuous and categorical ). The function is improved on the basis of tableone::CreateTableOne to become more convenient to use.

Usage

table1(
  var,
  strata,
  data,
  normal = c("age", "bmi", "sbp", "dbp"),
  catDigits = 1,
  contDigits = 1,
  pDigits = 3,
  showAllLevels = FALSE
)

Arguments

var

A vector of strings. Variables to be summarized given as a character vector.

strata

A vector of strings. Stratifying (grouping) variable name(s) given as a character vector.

data

A data frame in which these variables exist.

normal

A vector of strings, default = c("age", "bmi", "sbp", "dbp"). Show the mean and standard deviation of some variables.

catDigits

An integer, Number of decimal places in the table of continuous variables.

contDigits

An integer, Number of decimal places in the table of categorical variables.

pDigits

An integer, Number of decimal places in the table of p values.

showAllLevels

Bool, default = FALSE. If TRUE, the table contains all levels of categorical variables.

Value

An object describing baseline characteristics.

Examples

## Load Mayo Clinic Primary Biliary Cirrhosis Data
library(survival)
library(tableeasy)
data(pbc)
## Check variables
head(pbc)
## Make categorical variables factors
varsToFactor <- c('status','trt','ascites','hepato','spiders','edema','stage','sex')
pbc[varsToFactor] <- lapply(pbc[varsToFactor], factor)
##Table 1
table1(var=c('age','albumin','alk.phos','ast','edema','ascites','bili','chol'),strata='trt',pbc)
