tableDate {reporttools}R Documentation

Display descriptive statistics for date variables

Description

Many data analyses start with a display of descriptive statistics of important variables. This function takes a list of date variables and a possible grouping variable (such as e.g. treatment) and provides a Latex table of descriptive statistics separately per group and jointly for all observations, per variable.

Usage

tableDate(vars, nams, group = NA, subset = NA, disp.cols = c("n", 
    "min", "q1", "median", "mean", "q3", "max", "na"), 
     col.tit = NA, print.pval = TRUE, cap = "", lab = "")

Arguments

vars A list of date variables.
nams A vector of strings, containing the names corresponding to the variables in vars. These are the names that appear in the Latex table.
group Grouping variable, may be omitted.
subset Only consider a subset of observations.
disp.cols Specify which descriptive statistics should be displayed in the table.
col.tit Specify titles of columns.
print.pval If print.pval == TRUE, p-values of a Mann-Whitney or Kruskal-Wallis test for a difference between groups are provided.
cap The caption of the resulting Latex table.
lab The label of the resulting Latex table.

Value

Outputs the Latex table.

Examples

set.seed(1977)
diagnosis <- as.Date(round(runif(10, min = 35000, max = 40000)), 
    origin = "1899-12-30")
death <- as.Date(round(runif(10, min = 35000, max = 40000)), 
    origin = "1899-12-30")
vars <- list(diagnosis, death)
nams <- c("Diagnosis", "Death")
group <- sample(c(rep("A", 50), rep("B", 50)))
subset <- c(1:70, 91:100)
tableDate(vars, nams, group, subset, disp.cols = c("n", 
    "min", "q1", "median", "mean", "q3", "max", "na"), 
    col.tit = NA, print.pval = TRUE, cap = 
    "Table of date variables.", lab = "tab: descr stat date")
