Create a dt object

dt_create(
  data,
  group = NULL,
  stat_num = "median",
  digits = 2,
  spec_var = NULL,
  keep_missing = F,
  compare = T,
  overall = F
)

`data`	A data frame which contains only factor or numeric variables.
`group`	A variable name as characters or symbol which define groups.
`stat_num`	Characters. Specify the statistic to describe numeric variables, "median" (default) provides median, first and third quartiles, "mean" provides mean and standard deviation.
`digits`	Integer. Specify the number of digits to display.
`spec_var`	List. A named list of the variables for which you want specify row name, number of digits to display or just ordering the rows. Each variable-named element need to be a named list (with name and digit elements) or NULL. If provides here, the specific digit argument overwrite the general digits argument. The order of the variable-named element define the order of rows in the table.
`keep_missing`	Logical. If FALSE (default) observations which have a missing value for the grouping variable are exclude from the dataset. Otherwise an extra group named "Missing data" will be add to the table to describe this observations.
`compare`	Logical. If TRUE (default) a statistical comparison is added to the table.
`overall`	Logical. If TRUE an extra column with the statistics of the entire dataset will be added to the table.
