tableDate {reporttools} | R Documentation |
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.
tableDate(vars, nams, group = NA, subset = NA, stats = c("n", "min", "q1", "median", "mean", "q3", "max", "na"), col.tit = NA, print.pval = TRUE, cap = "", lab = "", disp.cols = NA)
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. |
stats |
Specify which descriptive statistics should be displayed in the table, by either directly providing one or more of the default character strings (in arbitrary order). |
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. |
disp.cols |
Only included for backward compatibility. Needs to be a vector of (some of) the default
statistics character strings if not equal to NA . From package version 1.0.2 use of stats is recommended. |
Outputs the LaTeX table.
