Split a Data Frame Based on a Chosen Variable

This function splits a data frame into a list of smaller data frames based on a specified variable (var) and its associated hierarchical variable (hrc_var). The function handles cases where hrc_var contains character values or is missing, ensuring that independent and hierarchical groupings are managed appropriately.

Usage

split_dataframe(tab, var, hrc_var)

Arguments

tab

A data frame to be split.

var

The variable to base the split on.

hrc_var

The hierarchical variable associated with var. If hrc_var is present, the data frame will first be split by its values; otherwise, it will be split directly by var.

Value

A list of data frames (list_diff), where each element corresponds to a grouping determined by var and/or hrc_var.

Examples

if (FALSE) { # \dontrun{
# Example data
tab <- data.frame(
  id = 1:6,
  var = c("A", "A", "B", "B", "C", "C"),
  hrc_var = c(NA, "H1", "H1", "H2", NA, NA),
  value = c(10, 20, 30, 40, 50, 60)
)

# Split by 'var' and 'hrc_var'
list_diff <- split_dataframe(tab, "var", "hrc_var")

# View the structure of the result
str(list_diff)
} # }
