Fill with aggregate by group

Description

Usage

  df,
  group,
  columns,
  overwrite_col = FALSE,
  statistic = mean,
  fill_empty_group = FALSE
)

Arguments

df	tibble to use
group	string or vector of strings: columns to group by
columns	string or vector of strings: columns to impute
overwrite_col	boolean: whether to overwrite column. If FALSE, a new column with suffix _imputed will be created
statistic	function: summary statistic to use (mean, median, min etc.). For now requires a function with na.rm argument
fill_empty_group	boolean: If TRUE, fills groups that only contain NA with summary statistic of entire column
