Introduction

This package provides a set of utility functions that are commonly used in the ‘LuLab’.

Data checks

data("melanoma", package = "boot")
check_cha("status", melanoma)
#> .
#>    1    2    3 
#> 0.28 0.65 0.07

Numeric rounding

round2(c(1.25, -1.25), digits = 1)
#> [1]  1.3 -1.3

Table 1

Table1() creates a stratified summary table and writes Table1.xlsx to the specified directory.

melanoma2 <- melanoma
melanoma2$status <- factor(
  melanoma2$status,
  levels = c(2, 1, 3),
  labels = c("Alive", "Melanoma death", "Non-melanoma death")
)

head(Table1(
  df = melanoma2,
  ycol = "status",
  xcol = c("time", "age", "sex"),
  result_dir = tempdir(),
  verbose = FALSE
))
