Format Baseline Characteristics Analysis

Format Baseline Characteristics Analysis

Usage

format_base_char(
  outdata,
  display_col = c("n", "prop", "total"),
  digits_prop = 1,
  display_stat = c("mean", "sd", "se", "median", "q1 to q3", "range")
)

Arguments

outdata

A metadata object created by prepare_sl_summary().

display_col

Column wants to display on the table. The term could be selected from c("n", "prop", "total").

digits_prop

Number of digits for proportion columns.

display_stat

A vector of statistics term name. The term name could be selected from c("mean", "sd", "se", "median", "q1 to q3", "range", "q1", "q3", "min", "max").

Value

A list of analysis raw datasets.
